Prior to 6.0.0, the CMS 5 password reset flow can issue a logged-in session after a user changes a password but before the user's configured multi-factor authentication challenge is completed. An attacker with access to the user's email account can follow the reset flow and bypass the additional authentication factor. CMS 6 is not affected. This issue is fixed in version 6.0.0.","cvssScore":4.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-288"],"vendors":[],"products":[],"references":[{"url":"https://github.com/silverstripe/silverstripe-framework/commit/4b5cbd7ddf68721d8119583f0b9c04d4b4adc704","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-framework/pull/11686","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/commit/04a102b662ac2f555acc26f8d2e2d8dab3937a6a","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/pull/603","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/releases/tag/6.0.0","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/security/advisories/GHSA-68wq-phq7-p2vg","tags":[]},{"url":"https://www.silverstripe.org/download/security-releases/cve-2026-55186","tags":[]}],"exploitRefs":[{"url":"https://github.com/silverstripe/silverstripe-framework/commit/4b5cbd7ddf68721d8119583f0b9c04d4b4adc704","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-framework/pull/11686","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/commit/04a102b662ac2f555acc26f8d2e2d8dab3937a6a","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/pull/603","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/releases/tag/6.0.0","tags":[]},{"url":"https://github.com/silverstripe/silverstripe-mfa/security/advisories/GHSA-68wq-phq7-p2vg","tags":[]}],"hasPoc":true,"ai":null}
