{"id":"CVE-2026-63458","published":"2026-09-18T18:17:10.643","lastModified":"2026-09-23T18:12:04.247","description":"Perses is an open-source dashboard and visualization project for observability data. Prior to 0.54.0-beta.3, an authenticated user with viewer access to one project can supply another project through the project query parameter on project-scoped list endpoints, including /api/v1/projects/{project}/dashboards and /api/v1/datasources. The request-controlled project value is used to select dashboards, datasources, and variables without enforcing the caller's authorization for that selected project, which breaks project-level tenant isolation and exposes complete resource specifications belonging to other projects. This issue is fixed in version 0.54.0-beta.3.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/perses/perses/commit/8015fb340bdc625953e73a7a688be5b939159540","tags":[]},{"url":"https://github.com/perses/perses/releases/tag/v0.54.0-beta.3","tags":[]},{"url":"https://github.com/perses/perses/security/advisories/GHSA-cjgj-2fwf-4c2w","tags":[]}],"exploitRefs":[{"url":"https://github.com/perses/perses/commit/8015fb340bdc625953e73a7a688be5b939159540","tags":[]},{"url":"https://github.com/perses/perses/releases/tag/v0.54.0-beta.3","tags":[]},{"url":"https://github.com/perses/perses/security/advisories/GHSA-cjgj-2fwf-4c2w","tags":[]}],"hasPoc":true,"ai":null}
