CVE-2025-53999Network attack vector

Unauthenticated unauthorized actions

Published Aug 20, 2026 · Updated Aug 20, 2026

Broken access control in ThemeGoods Altair through 5.2.2 allows remote attackers to perform unauthorized actions via unspecified vectors. Patchstack and NVD do not identify the affected endpoint, function, or missing check, so the named locus and faulty operation remain undisclosed in public records. Exposure is limited to internet-reachable WordPress sites running the commercial theme without authentication, but the published record does not show whether exploitation reaches option changes, privilege escalation, or only narrower state changes.
