Doc Text:
A flaw was found in Perses, an open-source dashboard and visualization project. An authenticated attacker can exploit a vulnerability in list endpoints that use the file-system database. By manipulating the `project` query parameter with directory traversal characters, an attacker can read arbitrary YAML or JSON files accessible to the Perses process. This bypasses project isolation and allows for the enumeration of other file-backed resources, leading to information disclosure.

Description OSIDB Bzimport 2026-09-22 20:53:29 UTC 
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.
