## Affected

- docmost: from 0.70.0, fixed in 0.70.3

## Description

Docmost is open-source collaborative wiki and documentation software. An authorization bypass vulnerability in versions 0.70.0 through 0.70.2 exposes restricted child page titles and text snippets through the public search endpoint (`POST /api/search/share-search`) for publicly shared content. This flaw allows unauthenticated users to enumerate and retrieve content that should remain hidden from public share viewers, leading to a confidentiality breach. Version 0.70.3 contains a patch.

## What to do
