CVE-2026-108582 Details
Description
GenOffice through 0.11.505 contains an incorrect permissions vulnerability in its HTTP MCP server file store that allows local unprivileged users to read uploaded and generated documents. Attackers can list the world-readable genoffice-mcp-http directory under the system temporary directory to read client uploads and converted outputs, bypassing the HTTP bearer token.
A vulnerability exists in GenOffice versions through 0.11.505, specifically within the HTTP Model Context Protocol (MCP) server file store. This vulnerability allows local unprivileged users to read documents uploaded by other clients, as well as files generated by certain tools, thereby bypassing the intended HTTP authorization mechanism. The issue arises because the file store creates directories and files with insecure permissions, leaving uploaded documents accessible to any user on the same system.
Users can update to GenOffice version 0.11.506 or later, where this vulnerability has been addressed.
