GHSA-6F75-X745-XCPR

Vulnerability from github – Published: 2026-06-23 22:24 – Updated: 2026-06-23 22:24
VLAI
Summary
Snipe-IT: Bulk editing users allowed `ldap_import` and `activated_in` bulk editing users
Details

Impact

The vulnerability allows a non-admin user holding only the granular users.edit permission to lock every admin out of the instance by editing the activated flag (which determines whether or not a user can login) and the ldap_import flag, which determines whether or not the user can request a password reset.

Patches

Details

SurrealDB versions before 3.2.0 contain a permissions bypass vulnerability where data-modifying statements within PERMISSIONS clauses execute with enforcement disabled. Attackers with permission to perform a guarded operation can write to tables they lack permission for by embedding CREATE, UPDATE, DELETE, or UPSERT statements in the PERMISSIONS clause, causing unintended writes and data corruption.

Vulnerability from github – Published: 2020-06-30 16:05 – Updated: 2021-01-07 23:49
VLAI
Summary
Authorization bypass in express-jwt
Details

Overview

Versions before and including 5.3.3, we are not enforcing the algorithms entry to be specified in the configuration. When algorithms is not specified in the configuration, with the combination of jwks-rsa, it may lead to authorization bypass.

Am I affected?

You are affected by this vulnerability if all of the following conditions apply:

You are using express-jwt AND You do not have algorithms configured in your express-jwt configuration. AND You are using libraries such as jwks-rsa as the secret.

How to fix that?

Specify algorithms in the express-jwt configuration. The following is an example of a proper configuration

const checkJwt = jwt({
  secret: jwksRsa.expressJwtSecret({
    rateLimit: true,
    jwksRequestsPerMinute: 5,
    jwksUri: `https://${DOMAIN}/.well-known/jwks.json`
  }),
  // Validate the audience and the issuer.
  audience: process.env.AUDIENCE,
  issuer: `https://${DOMAIN}/`,
  // restrict allowed algorithms
  algorithms: ['RS256']
});

Will this update impact my users?

The fix provided in patch will not affect your users if you specified the algorithms allowed. The patch now makes algorithms a required configuration.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
