FKIE_CVE-2026-48072

Vulnerability from fkie_nvd - Published: 2026-09-24 19:17 - Updated: 2026-09-24 19:17
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
Docmost is open-source collaborative wiki and documentation software. Prior to 0.80.1, the public avatar and logo image endpoint accepts attacker-controlled fileName path segments and resolves them against local storage without confinement to the intended image directory. An unauthenticated attacker can traverse outside the avatar or logo directory and read local storage objects whose final basename satisfies the route's UUID check. This issue is fixed in version 0.80.1.
