| Title | KodExplorer 4.52 Authorization Bypass |
|---|
| Description | KodExplorer v4.52 contains a post-authentication authorization bypass in systemRole/get that allows a low-privilege user to modify global group permission templates. By abusing the group_role parameter, an attacker can overwrite the built-in read-only template and add write permissions such as write:add. Once the template is changed, ordinary users assigned to public groups with read-only membership are immediately granted write access and can create files in shared locations. This results in a real privilege escalation and global ACL corruption rather than a simple interface flaw.
