On multi-tenant deployments running the opt-in stigmem-plugin-multi-tenant, the list/count queries and _get_quarantined_fact in routes/quarantine.py lacked a tenant_id predicate and the garden lookup was not tenant-scoped, allowing a tenant administrator with only a plain tenant write capability to list, read, and admit or reject quarantined facts belonging to other tenants via the /v1/quarantine endpoints. Default single-tenant deployments are not affected.","published":"2026-08-19T14:02:15.899Z","modified":"2026-08-23T03:42:56.273882680Z","cvss":null,"epss":{"score":0.0029,"percentile":0.21463,"asOf":"2026-09-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"stigmem-node","fixedVersion":"0.9.0a12"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76237.json"},{"type":"ADVISORY","url":"https://github.com/eidetic-labs/stigmem/security/advisories/GHSA-xhv3-q4xx-349r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76237"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/stigmem-before-0a12-cross-tenant-bola-via-quarantine"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-23T03:42:56.273882680Z"}}
