# VanBlog: unauthenticated requests read private and hidden articles

Link for people: https://infrastack.ai/live/CVE-2026-125376 (this .md is for agents)

VanBlog, a self-hosted blog, exposes private and hidden articles through its public article endpoint. An unauthenticated attacker can read full article content by submitting any non-empty password or requesting a hidden article by ID.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:VanBlog affected range not listed fixed no fixed version listed

## How to check

- Check the installed VanBlog version and compare it with the fixed release in the sources.
- Test `POST /api/public/article/:id` on a hidden or private article with any non-empty password and see whether the full content is returned.

## Documents

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/vanblog-through-0.54.0-private-article-disclosure-via-public-password-endpoint
- [fix] Patch: github.com https://github.com/Mereithhh/vanblog/commit/81b868f4d568c8accff62b9c35d0e556d1e7970d

## From the sources

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.
