{"cve":"CVE-2026-34198","nvd":{"published":"2026-07-07T04:17:50.847","modified":"2026-10-25T20:10:00.147","status":"Deferred","description":"Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, the TrustProxies middleware trusts all proxies ($proxies = '*'), accepting X-Forwarded-Host from any source. The TrustHosts middleware, intended to prevent host header attacks, has a circular caching dependency that prevents it from ever validating hosts. When a password reset is requested, the ResetPassword notification generates the reset URL using url(route(..., false)), which derives the host from the (spoofable) request. An unauthenticated attacker can trigger a password reset email containing a link pointing to an attacker-controlled domain, enabling token theft and account takeover. This issue is fixed in version 4.0.0-beta.471.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N","score":5.3},"cwes":["CWE-346","CWE-640"],"references":["https://github.com/coollabsio/coolify/commit/98569e4edbfc316877c9e0d27ea89fab3c49e3bd","https://github.com/coollabsio/coolify/pull/9193","https://github.com/coollabsio/coolify/releases/tag/v4.0.0-beta.471","https://github.com/coollabsio/coolify/security/advisories/GHSA-cgj8-7m5q-x5gv","https://github.com/coollabsio/coolify/security/advisories/GHSA-cgj8-7m5q-x5gv"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:34.550481224+00:00"},"epss":{"cve":"CVE-2026-34198","score":0.00201,"percentile":0.09877,"date":"2026-10-25"},"kev":null,"osv":[],"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).
