In versions older than 4.2 the token is not invalidated after the first successful password change, allowing a local attacker who has access to a valid token to use it again to set a new password for any account. This flaw directly undermines account integrity and is classified as CWE\u2011613, a failure to correctly invalidate a credential after use.", "risk_and_exploitability": "The CVSS score of 7.8 marks the flaw as high severity, while the EPSS score of less than 1% indicates a very low current exploitation probability and the vulnerability is not listed in the CISA KEV catalog. Nevertheless, a local attacker who can acquire a reset token can reuse it to take over an account, so the potential impact is significant if the attacker gains local or token access. The flaw can be exploited through a local attack vector that leverages the token reuse capability."}}}}, "created": "2026-02-04T12:09:18.631643+00:00", "updated": "2026-04-18T14:15:04.138212+00:00", "vendors": ["openeclass", "openeclass$PRODUCT$openeclass"]}
