CVE-2026-116073 Details
Description
Leon before commit 50df142 contains a path traversal vulnerability in getModelFileNameFromURL() that allows attackers to write files outside the models directory via percent-encoded separators. Attackers can trick a user into running '/download model' with a crafted URL containing encoded '../' sequences to write attacker-controlled content to arbitrary paths writable by Leon.
A path traversal vulnerability has been identified in Leon, prior to commit 50df142. The issue resides in the 'getModelFileNameFromURL' function, where percent-encoded separators are improperly handled. This flaw allows attackers to write files outside the designated models directory by encoding '../' sequences in a crafted URL. When a user executes the '/download model' command with such a URL, the application writes the file to a location controlled by the attacker, exploiting the way file paths are processed.
Users can update to the latest version of Leon, where this vulnerability has been fixed.
