CVE-2021-42749Public exploitNetwork attack vector

Unauthenticated disclosure via archive excerpt

Published Jan 7, 2022 · Updated Aug 4, 2024

Information disclosure in Beaver Themer before 2.5.1 allows remote attackers to view conditionally hidden content via post archives. Archive and post-loop rendering falls back to WordPress post_content excerpts, which retain modules hidden by Themer conditional logic when no excerpt is set. Exploitation requires a Themer archive layout and an unset excerpt; exposed data is read-only content disclosure.
