CVE-2026-3454Network attack vector

Authenticated post-data disclosure via unchecked identifiers

Published May 5, 2026 · Updated May 5, 2026

IDOR in GenerateBlocks 2.2.0 and earlier allows remote authenticated users to read arbitrary post data through dynamic-tag REST requests. The dynamic-tag-replacements endpoint checks edit_posts but fails to authorize attacker-supplied post IDs before returning post metadata or author email addresses. Contributor-level access is required, and exposure is limited to data reachable through supported dynamic tags, including non-protected post metadata.
