Unauthenticated submitter data disclosure via REST authorization failure
Published Oct 3, 2026 · Updated Oct 3, 2026
Information disclosure in Wpmet MetForm before 4.3.1 allows remote attackers to read form submitter data through its REST API. The form-entry REST API returns submission information without adequately restricting access to authorized requesters. An unauthenticated network request can expose saved submitter information; the reviewed public advisories do not identify the exact route or returned fields.
