CVE-2026-67246

Estado: AnalizadaMedia (6.9)—

A path traversal vulnerability was found in the Wallpaper component of ADM. The vulnerability occurs because user-controlled wallpaper path input is not sufficiently validated before being used for file access. An authenticated attacker can exploit this issue to access or manipulate files outside the intended wallpaper directory, subject to user permissions and filesystem restrictions. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.
