# Vvveb CMS: low-privilege authors can read other authors' draft revisions

Link for people: https://infrastack.ai/live/CVE-2026-126373 (this .md is for agents)

Vvveb 1.0.8.4 through 1.0.8.6 has an authorization bypass in the content/revisions action, which lacks an ownership check. An authenticated low-privileged author can supply a post_id, language_id and created_at timestamp to read other authors' unpublished drafts.

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

## How to check

- Check the installed Vvveb version and whether it falls in `1.0.8.4` through `1.0.8.6`
- Review access to the content/revisions action for non-admin author accounts

## From the sources

Vvveb 1.0.8.4 through 1.0.8.6 contains an authorization bypass vulnerability in the content/revisions revision action that lets low-privileged Authors read other authors' revisions. Attackers can supply a post_id, language_id, and created_at timestamp to retrieve private unpublished drafts, because the revision() action lacks the admin_id ownership restriction.
