Summary
ChronoFrame through 1.0.0 contains a missing authentication vulnerability (CWE-306) in the server/api/wizard/ handlers, so unauthenticated attackers can reconfigure instances that are already set up. A POST to /api/wizard/storage activates an attacker-controlled S3 or OpenList provider, redirecting uploads and storage reads, and overwrites site and map settings. The CVSS 4.0 base score is 8.8 (HIGH), and the CNA is GitHub. CISA rates exploitation as PoC, automatable yes, technical impact partial, and no fixed version is listed.
