Description
B3log Solo through 4.4.0 contains a missing authorization vulnerability in ArticleConsole that allows authenticated authors to access other authors' articles by omitting per-author ownership checks. Attackers can query the console articles status endpoint to list other authors' drafts, probe draft content via the k parameter, and use push2rhy to push others' articles to the Rhythm community.
