Medium (6.9) in mereithhh vanblog. EPSS 0.3% estimated probability of exploitation activity in the next 30 days.

On this page
VanBlog through 0.54.0 contains an information disclosure vulnerability that allows unauthenticated attackers to read private and hidden articles via the POST /api/public/article/:id endpoint. Attackers can submit any non-empty password for private articles lacking an effective password, or request hidden articles, since getByIdWithPassword never checks the hidden flag, exposing full article content.
