{"cve":"CVE-2026-63458","nvd":{"published":"2026-09-18T18:17:10.643","modified":"2026-09-23T18:12:04.247","status":"Awaiting Analysis","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.","cvss_v4":{"vector":"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","score":7.1},"cvss_v3":null,"cwes":["CWE-639"],"references":["https://github.com/perses/perses/commit/8015fb340bdc625953e73a7a688be5b939159540","https://github.com/perses/perses/releases/tag/v0.54.0-beta.3","https://github.com/perses/perses/security/advisories/GHSA-cjgj-2fwf-4c2w"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-63458","score":0.00414,"percentile":0.3567,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cjgj-2fwf-4c2w","url":"https://osv.dev/vulnerability/GHSA-cjgj-2fwf-4c2w","summary":"Perses's project query parameter authorization bypass exposes cross-project resources","modified":"2026-09-28T17:10:52.933082102Z","packages":[{"ecosystem":"Go","name":"github.com/perses/perses","purl":"pkg:golang/github.com/perses/perses","ranges":["<0.54.0-beta.3"],"fixed":["0.54.0-beta.3"]}]},{"id":"GO-2026-6518","url":"https://osv.dev/vulnerability/GO-2026-6518","summary":"Perses's project query parameter authorization bypass exposes cross-project resources in github.com/perses/perses","modified":"2026-09-28T17:00:16.146910943Z","packages":[{"ecosystem":"Go","name":"github.com/perses/perses","purl":"pkg:golang/github.com/perses/perses","ranges":["<0.54.0-beta.3"],"fixed":["0.54.0-beta.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
