CVE-2026-55445 whyour CVE debrief

Who should care

Users of Qinglong timed task management platform versions prior to 2.20.1 should update to 2.20.1 or later to prevent unauthorized administrator credential resets. Affected operators, platform administrators, vulnerability management teams, and security teams should review instance configurations and monitor for potential exploitation attempts.

Technical summary

The init guard middleware in Qinglong's back/loaders/express.ts checks /api/user/init but not /open/user/init. The rewrite('/open/*', '/api/$1') rule rewrites whitelisted /open/* paths after JWT authentication and guard have passed. This allows an unauthenticated attacker to send a PUT request to /open/user/init, potentially resetting administrator credentials on an initialized instance. Affected operators, platform administrators, vulnerability management teams, and security teams should review instance configurations and monitor for potential exploitation attempts to prevent unauthorized administrator credential resets. This issue allows for potential unauthorized administrator credential resets on affected instances. The CVE record was published on 2026-07-15T22:17:26.020Z and was last modified on 2026-07-16T13:52:58.290Z. The NVD entry is currently Deferred. Evidence is limited to CVE and NVD details. Defenders should verify instance configurations and monitor for unauthorized credential reset attempts.
