CVE-2026-35174 is a critical path traversal vulnerability in the Chyrp Lite blogging engine prior to version 2026.01. It allows an administrator or a user with Change Settings permission to manipulate the uploads path to arbitrary directories. This enables unauthorized downloading of sensitive files such as configuration files containing database credentials and overwriting critical system files, potentially leading to remote code execution. The vulnerability is fixed in version 2026.01.

Chyrp Lite is an ultra-lightweight blogging engine. Prior to 2026.01, an IDOR / Mass Assignment issue exists in the Post model that allows authenticated users with post editing permissions (Edit Post, Edit Draft, Edit Own Post, Edit Own Draft) to modify posts they do not own and do not have permission to edit. By passing internal class properties such as id into the post_attributes payload, an attacker can alter the object being instantiated. As a result, further actions are performed on another user’s post rather than the attacker’s own post, effectively enabling post takeover. This vulnerability is fixed in 2026.01.
