{"id":"GHSA-cjgj-2fwf-4c2w","summary":"Perses's project query parameter authorization bypass exposes cross-project resources","details":"### Impact\n_What kind of vulnerability is it?_\n\nAn authenticated user who is only a viewer on project team-a requests GET /api/v1/projects/team-a/dashboards?project=finance-secret (or simply GET /api/v1/datasources?project=finance-secret) and receives the full list of the finance-secret project's dashboards and datasource specifications, despite having no role on that project. This defeats Perses' project-level tenant isolation for all project-scoped read resources.\n\n_Who is impacted?_\n\nAny authenticated user reads every project's dashboards, datasources, variables across tenants.\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\n### Workarounds\nNone","aliases":["CVE-2026-63458"],"modified":"2026-09-18T17:45:05.850557114Z","published":"2026-09-18T17:39:31Z","database_specific":{"github_reviewed_at":"2026-09-18T17:39:31Z","nvd_published_at":null,"cwe_ids":["CWE-639"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/perses/perses/security/advisories/GHSA-cjgj-2fwf-4c2w"},{"type":"WEB","url":"https://github.com/perses/perses/commit/8015fb340bdc625953e73a7a688be5b939159540"},{"type":"PACKAGE","url":"https://github.com/perses/perses"},{"type":"WEB","url":"https://github.com/perses/perses/releases/tag/v0.54.0-beta.3"}],"affected":[{"package":{"name":"github.com/perses/perses","ecosystem":"Go","purl":"pkg:golang/github.com/perses/perses"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.54.0-beta.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-cjgj-2fwf-4c2w/GHSA-cjgj-2fwf-4c2w.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
