Description
A path guard bypass exists in the MCP file-access handler due to the use of case-sensitive matching on Linux filesystems. This allows an attacker to read the protected
publishAccess.json file by requesting case-variant paths, such as PublishAccess.json, leading to the disclosure of sensitive publish-access configuration and metadata.Recommendations
Update to version 3.8.2 or later.
