In version 2.11.3 and earlier, three configuration-dependent weaknesses affect the handler and placeholder layer. In modules/caddyhttp/rewrite/rewrite.go, Rewrite.Rewrite() can pass attacker-controlled replacement bytes through buildQueryString for a second placeholder expansion when a rewrite URI ends with a literal question mark, allowing injected environment or request-variable placeholders to disclose data and, when the file provider is registered, allowing injected file placeholders to disclose readable files. The  issue is fixed in version 2.11.4.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","score":6.5,"severity":null}],"references":["https://github.com/caddyserver/caddy/security/advisories/GHSA-j8px-rmrx-76h9","https://github.com/caddyserver/caddy/pull/7761","https://github.com/caddyserver/caddy/commit/176b043b0104cee3f894023cd5a598ac29e404bb","https://github.com/caddyserver/caddy/releases/tag/v2.11.4"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-82474","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 17, 2026, 9:04:58 PM","dateUpdated":"Sep 18, 2026, 2:43:34 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
