Summary

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.

Risk Assessment

The risk includes unauthorized access to sensitive documents processed by GenOffice, potentially leading to data leakage.

Recommendation

Upgrade GenOffice to a version newer than 0.11.505 and change permissions of the temporary directory to prevent reading by unprivileged users.
