The Meow Gallery WordPress plugin before 5.5.5 does not perform a proper capability check or restrict results to the requesting user's own posts before returning post data, allowing authenticated users with Author-level access and above to disclose the titles, authors, dates and statuses of other users' draft and private posts.
AnalysisAI
Information disclosure in the Meow Gallery WordPress plugin before 5.5.5 lets authenticated users holding Author-level access or higher pull back metadata - titles, authors, dates and publish statuses - belonging to other users' draft and private posts. The vulnerable post-data retrieval routine performs neither a proper capability check nor owner-scoping of results, so a low-trust Author account on a multi-author site can enumerate unpublished content it was never meant to see; post bodies themselves are not exposed and there is no write, modify or denial-of-service impact. …
