An attacker could inject a condition that widened the filter to match every row, turning an intended single-row operation into full-table disclosure, deletion, or modification.","published":"2026-08-20T11:21:06.912Z","modified":"2026-08-22T03:58:13.679322057Z","cvss":null,"epss":{"score":0.00272,"percentile":0.19725,"asOf":"2026-08-21"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77071.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-f4f3-2g67-4vhm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77071"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/n8n-before-postgrest-filter-injection-via-supabase"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-22T03:58:13.679322057Z"}}
