{"id":"CVE-2026-63458","summary":"Perses project query parameter authorization bypass exposes cross-project resources","details":"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.","aliases":["GHSA-cjgj-2fwf-4c2w"],"modified":"2026-09-19T11:30:27.173793517Z","published":"2026-09-18T17:32:54.847Z","related":["openSUSE-SU-2026:11413-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63458.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63458.json"},{"type":"FIX","url":"https://github.com/perses/perses/commit/8015fb340bdc625953e73a7a688be5b939159540"},{"type":"WEB","url":"https://github.com/perses/perses/releases/tag/v0.54.0-beta.3"},{"type":"ADVISORY","url":"https://github.com/perses/perses/security/advisories/GHSA-cjgj-2fwf-4c2w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63458"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/perses/perses","events":[{"introduced":"0"},{"fixed":"823d025f35d555fe7fed03d765b6412a2db8f45b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.54.0-beta.3"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.54.0-beta.2","v0.53.0-rc.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63458.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"}]}
