# MrDoc: registered users can reorder and hide other users' documents

Link for people: https://infrastack.ai/live/CVE-2026-125375 (this .md is for agents)

MrDoc, a self-hosted documentation wiki, does not check ownership in its document sorting handlers. A registered user can supply arbitrary document IDs to move other users' documents or set them to draft or removed, hiding published content.

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

## How to check

- Check whether the MrDoc version in use is `1.1.1` or earlier, as the sources say the flaw runs through `1.1.1`.
- Look for the `project_doc_sort` and `manage_project_doc_sort` handlers in the MrDoc source code.

## Documents

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/mrdoc-through-1.1.1-missing-authorization-via-project-document-sort-handlers
- [fix] Patch: github.com https://github.com/zmister2016/MrDoc/commit/e2c26d7858289601dde331b205b82ea5e2d2dad1

## From the sources

MrDoc through 1.1.1 contains a missing authorization vulnerability in the project_doc_sort and manage_project_doc_sort handlers that allows registered users to modify other users' documents by supplying arbitrary document IDs in sort_data. Attackers owning any project can reparent and reorder documents by sequential ID and set their status to draft or removed, hiding published documents.
