{"id":"BIT-authentik-2024-47070","summary":"authentik vulnerable to password authentication bypass via X-Forwarded-For HTTP header","details":"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.","aliases":["CVE-2024-47070","GHSA-7jxf-mmg9-9hg7"],"modified":"2026-09-08T08:45:50.109801155Z","published":"2026-04-16T23:36:17.967Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:goauthentik:authentik:*:*:*:*:*:go:*:*"]},"references":[{"type":"FIX","url":"https://github.com/goauthentik/authentik/commit/78f7b04d5a62b2a9d4316282a713c2c7857dbe29"},{"type":"FIX","url":"https://github.com/goauthentik/authentik/commit/dd8f809161e738b25765797eb2a5c77a7d3fc2cf"},{"type":"ADVISORY","url":"https://github.com/goauthentik/authentik/security/advisories/GHSA-7jxf-mmg9-9hg7"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-47070"}],"affected":[{"package":{"name":"authentik","ecosystem":"Bitnami","purl":"pkg:bitnami/authentik"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2024.6.5"},{"introduced":"2024.8.0"},{"fixed":"2024.8.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/authentik/BIT-authentik-2024-47070.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
