"According to its self-reported version, the instance of Gogs running on the remote host is prior or equal to 0.13.3.
It is, therefore, affected by multiple vulnerabilities, including:

  - Improper Symbolic link handling in the PutContents API in Gogs allows Local Execution of Code. (CVE-2025-8110)

  - Due to the insufficient patch for CVE-2024-56731, it is still possible to update files in the .git directory and
    achieve remote command execution. (CVE-2025-64111)

  - An arbitrary file read/write via path traversal exists in Git hook editing. (CVE-2026-23633)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
