Unlike get_api_signIn, which enforces a rate limit of 10 attempts per 5 minutes via checkRateLimit(), get_api_preauthorize performs the same credential check with no throttling for any client, allowing unlimited remote password guessing against arbitrary accounts, including admin. The endpoint also acts as a credential oracle: it returns the message \"Invalid credentials\" for both correct and incorrect passwords, while the users_id field in the response body discloses the authenticated identity (users_id:1 on success, users_id:0 on failure), and a correct password establishes a session cookie that remains usable for authenticated API requests. Together these issues permit unauthenticated brute-force account takeover.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":40.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
