Protected post excerpts disclosed through Open Graph tags
Published Apr 1, 2024 · Updated Mar 20, 2025
Information disclosure in NerdPress Hubbub Lite before 1.33.1 allows remote attackers to read excerpts from password-protected posts. The Open Graph generator emits protected post content into the public og:description meta tag without first verifying the viewer's password authorization. The flaw is reachable without authentication when Open Graph meta tags are enabled, and the exposed data is limited to short post excerpts.
