Attackers can send forged X-Forwarded-For values through appending proxies to bypass per-IP rate limits on login, one-time passcode, and password validation endpoints, enabling brute-force attacks, and to falsify IP addresses recorded in audit logs.","categories":["Unclassified"],"product":"coder","vendor":"coder","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-111934","source_modified_at":"2026-10-19T16:39:17.593Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"coder","vendor":"coder","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"2.34.7"},{"version":"2.34.7","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-111934","source_modified_at":"2026-10-19T16:39:17.593Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"coder","ecosystem":null},"version":"2.34.7","basis":"first unaffected version stated in the CVE record"}],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00123,"percentile":0.01884,"score_date":"2026-10-23"},"published_at":"2026-10-17T18:46:44.142Z","modified_at":"2026-10-19T16:39:17.593Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-111934","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T16:39:17.593Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-111934","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/coder/coder/security/advisories/GHSA-vprw-xcrv-287h","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/coder-before-2.34.7-ip-spoofing-via-x-forwarded-for-header","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-19T15:35:37.487571Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-19T16:39:17.593Z","content_hash":"ee95de3eedeffe362fe0a9a8608c8bc1210e16b92be49ed74f8f3881d641a3ce"}}
