CVE-2024-45297Network attack vector

Hidden-topic disclosure via unauthorized tag filtering

Published Oct 7, 2024 · Updated Oct 8, 2024

Improper privilege management in Discourse before stable 3.3.2 and beta 3.4.0.beta2 allows remote attackers to view hidden-tag topics. Topic-list filtering accepts a known hidden-tag label without enforcing the tag's visibility restriction; the vendor has not disclosed the responsible code locus. Exploitation requires knowledge of the tag label and a site containing topics under that restriction, and the reported consequence is read-only disclosure.
