How do I detect CVE-2025-48948 in my Go dependencies?

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.

How do I mitigate CVE-2025-48948 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2025-48948 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-48948 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-48948?

CVE-2025-48948 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 44th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-48948?

CVE-2025-48948 is classified as CWE-863 (CWE-863). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2025-48948 published, and has it been updated?

CVE-2025-48948 was published on May 30, 2025 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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
Host: 192.168.199.134:4533

{"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.
