What is CVE-2026-25525?

The OpenMage LTS Dataflow module, prior to version 20.17.0, is susceptible to a path traversal vulnerability due to a weak blacklist filter used for input sanitization. Attackers, particularly authenticated administrators, can exploit this vulnerability by crafting specific input patterns such as ..././ or ....//, effectively bypassing the filter. This allows unauthorized access to arbitrary files on the server, posing a significant risk to the integrity of the system. It is crucial for users operating on affected versions to upgrade to 20.17.0 or later to ensure their systems are secured against this exploit.

Affected Version(s)
