CVE-2026-77026Network attack vector

Submission disclosure via missing access control

Published Aug 20, 2026 · Updated Aug 21, 2026

Access control bypass in Tassos Convert Forms before 5.2.5 allows remote attackers to read form submissions via the front end. The front-end Submissions view exposes the submissions list without enforcing a server-side permission check, so unauthenticated requests can retrieve stored entries. Exposure depends on a site publishing the Submissions menu type for a form; the available evidence describes read access only, not modification or deletion.
