From 2.4.0 until 2.11.3, the authorization layer and the /config traversal layer do not agree on what object the path refers to. In this case, a path authorized for one config object is accepted, but then resolves to a different config object during traversal. This happens because the authorization layer uses string prefix matching and the /config traversal layer parses array indices numerically using strconv.Atoi(). This vulnerability is fixed in 2.11.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N","score":3.8},"cwes":["CWE-187","CWE-863"],"references":["https://github.com/caddyserver/caddy/security/advisories/GHSA-x5w9-xh9r-mvfc","https://github.com/caddyserver/caddy/security/advisories/GHSA-x5w9-xh9r-mvfc"],"products":["caddyserver:caddy"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-45692","score":0.00241,"percentile":0.15124,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-x5w9-xh9r-mvfc","url":"https://osv.dev/vulnerability/GHSA-x5w9-xh9r-mvfc","summary":"Caddy: Remote Admin Authorization Bypass in `/config` API via Array Index Normalization","modified":"2026-07-20T14:00:26.975712219Z","packages":[{"ecosystem":"Go","name":"github.com/caddyserver/caddy/v2","purl":"pkg:golang/github.com/caddyserver/caddy/v2","ranges":[">=2.4.0 <2.11.3"],"fixed":["2.11.3"]}]},{"id":"GO-2026-5743","url":"https://osv.dev/vulnerability/GO-2026-5743","summary":"Remote Admin Authorization Bypass in \"/config\" API via Array Index Normalization in github.com/caddyserver/caddy","modified":"2026-07-07T20:30:14.960575546Z","packages":[{"ecosystem":"Go","name":"github.com/caddyserver/caddy/v2","purl":"pkg:golang/github.com/caddyserver/caddy/v2","ranges":[">=2.4.0 <2.11.3"],"fixed":["2.11.3"]}]}],"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).
