Vulnerability 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.
