Perses is an open-source dashboard and visualization project for observability data. Prior to 0.54.0-rc.0, list endpoints used with the file-system database bind the request-controlled project query parameter into the resource Query structure without validating it against directory traversal characters, and the resulting project value is used to select database paths. An authenticated attacker can supply directory traversal segments to leave the intended project directory, read arbitrary YAML or JSON files accessible to the Perses process, and bypass project isolation to enumerate other file-backed resources. This issue is fixed in version 0.54.0-rc.0.
