Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Perses versions before 0.54.0-rc.0 are vulnerable when they use the file system database. The project parameter on list endpoints is not validated for directory-traversal characters, so an attacker who can send requests to the server can read arbitrary YAML or JSON files on the host and reach other resources in the file database. Upgrade to 0.54.0-rc.0 or later. Using a SQL database instead of the file system database avoids the issue.
