CVE-2025-67737

An API endpoint that is intended for internal use by the SFTP software sftpgo was mistakenly exposed to the public-facing HTTP API for AzuraCast installations.

This would allow a user with specific internal knowledge of a station's operations to craft a custom HTTP request that would affect the contents of a station's database, without revealing any internal information about the station.

With a request like:

curl -s -X POST "http://localhost/api/internal/sftp-event"   -H "Content-Type: application/json"   -d '{
    "action": "pre-delete",
    "username": "admin",
    "path": "/var/azuracast/stations/test/media/test.mp3"
}'

A remote user could simulate a request from sftpgo informing the software that a file was about to be deleted from the path given. In anticipation of this, AzuraCast would delete the corresponding database record for that file. While AzuraCast would then later discover on its own that the file actually exists and recreate the media record, it would not have the same playlist associations or custom metadata as the previous instance of the media record in the database.

Some mitigating factors affecting the severity of this issue include:

• A user would need to know a valid SFTP username corresponding to the specific station in question.
• A user would need to know the internal filesystem structure of a station (or be able to brute-force or guess paths).
• Any call to this internal API endpoint does not return any information to the calling process about what files are present or aren't, so no confidential internal information is revealed by this process.

Patched versions of AzuraCast specifically check that any calls to this internal URL are being called by the internal HTTP service, which only listens for activity on localhost and is not accessible from outside the container.

The application does not perform an authorization check before performing a sensitive operation. Typical impact: unauthorized access to restricted functionality or data.

CVE-2025-67737 has a CVSS score of 3.1 (Low). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.23.2); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2025-67737? CVE-2025-67737 is a low-severity missing authorization vulnerability in azuracast/azuracast (composer), affecting versions <= 0.23.1. It is fixed in 0.23.2. The application does not perform an authorization check before performing a sensitive operation.
2. How severe is CVE-2025-67737? CVE-2025-67737 has a CVSS score of 3.1 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of azuracast/azuracast are affected by CVE-2025-67737? azuracast/azuracast (composer) versions <= 0.23.1 is affected.
4. Is there a fix for CVE-2025-67737? Yes. CVE-2025-67737 is fixed in 0.23.2. Upgrade to this version or later.
5. Is CVE-2025-67737 exploitable, and should I be worried? Whether CVE-2025-67737 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.

6. What actually determines whether CVE-2025-67737 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.
7. How do I fix CVE-2025-67737? Upgrade azuracast/azuracast to 0.23.2 or later.
