{"cve":"CVE-2024-47070","nvd":{"published":"2024-09-27T16:15:05.413","modified":"2026-06-17T07:56:29.453","status":"Analyzed","description":"authentik is an open-source identity provider. A vulnerability that exists in versions prior to 2024.8.3 and 2024.6.5 allows bypassing password login by adding X-Forwarded-For header with an unparsable IP address, e.g. `a`. This results in a possibility of logging into any account with a known login or email address. The vulnerability requires the authentik instance to trust X-Forwarded-For header provided by the attacker, thus it is not reproducible from external hosts on a properly configured environment.  The issue occurs due to the password stage having a policy bound to it, which skips the password stage if the Identification stage is setup to also contain a password stage. Due to the invalid X-Forwarded-For header, which does not get validated to be an IP Address early enough, the exception happens later and the policy fails. The default blueprint doesn't correctly set `failure_result` to `True` on the policy binding meaning that due to this exception the policy returns false and the password stage is skipped. Versions 2024.8.3 and 2024.6.5 fix this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","score":9.0},"cwes":["CWE-287"],"references":["https://github.com/goauthentik/authentik/commit/78f7b04d5a62b2a9d4316282a713c2c7857dbe29","https://github.com/goauthentik/authentik/commit/dd8f809161e738b25765797eb2a5c77a7d3fc2cf","https://github.com/goauthentik/authentik/security/advisories/GHSA-7jxf-mmg9-9hg7"],"products":["goauthentik:authentik"],"source":"nvd","synced_at":"2026-10-19T21:55:31.737901711+00:00"},"epss":{"cve":"CVE-2024-47070","score":0.00563,"percentile":0.46835,"date":"2026-11-01"},"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).
