Summary
Navidrome Transcoding Permission Bypass Vulnerability Report
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.
The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is CVE-2025-48948? CVE-2025-48948 is a high-severity incorrect authorization vulnerability in github.com/navidrome/navidrome (go), affecting versions <= 0.55.2. It is fixed in 0.56.0. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
- Which versions of github.com/navidrome/navidrome are affected by CVE-2025-48948? github.com/navidrome/navidrome (go) versions <= 0.55.2 is affected.
- Is there a fix for CVE-2025-48948? Yes. CVE-2025-48948 is fixed in 0.56.0. Upgrade to this version or later.
- Is CVE-2025-48948 exploitable, and should I be worried? Whether CVE-2025-48948 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-48948 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2025-48948? Upgrade
