# CVE-2026-125376: VanBlog through 0.54.0 Private Article Disclosure via Public Password Endpoint

Status: published. Published: 2026-11-09. Updated: 2026-11-09.

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.
