By sending a specially crafted host header in the forgot password request, it is possible to send password reset links to users which, once clicked, lead to an attacker-controlled server and thus leak the password reset token. This may allow an attacker to reset other users' passwords and take over their accounts.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-74"],"references":["https://github.com/dub-flow/vulnerability-research/tree/main/CVE-2023-39655","https://www.npmjs.com/package/%40perfood/couch-auth","https://github.com/dub-flow/vulnerability-research/tree/main/CVE-2023-39655","https://www.npmjs.com/package/%40perfood/couch-auth"],"products":["perfood:couchauth"],"source":"nvd","synced_at":"2026-10-19T21:43:38.875533635+00:00"},"epss":{"cve":"CVE-2023-39655","score":0.00525,"percentile":0.44556,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-fqh6-6h6c-366m","url":"https://osv.dev/vulnerability/GHSA-fqh6-6h6c-366m","summary":"CouchAuth host header injection vulnerability leaks the password reset token","modified":"2024-01-03T22:41:43.878553Z","packages":[{"ecosystem":"npm","name":"@perfood/couch-auth","purl":"pkg:npm/%40perfood/couch-auth","ranges":["<=0.20.0"],"fixed":[]}]}],"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).
