The vulnerability arises from insufficient sanitization and output escaping of user\u2011supplied attributes that are recorded by the plugin whenever the logging feature is enabled. When a logged\u2011in user opens the log page, the injected code runs in the victim\u2019s browser, potentially dropping malicious scripts or compromising session data. The primary weakness is a classic client\u2011side injection (CWE\u201179).", "risk_and_exploitability": "The CVSS score of 6.1 reflects medium severity, indicating that while the vulnerability is not immediately catastrophic, it can lead to significant compromise if exploited in a session\u2011tainting context. The EPSS score is not available, and the issue is not listed in the CISA KEV catalog, suggesting limited public exploitation yet. The attack is inferred to be an unauthenticated request to the wwa_auth AJAX endpoint, which makes it easily exploitable by any visitor able to load the log page after the payload is stored."}}}}, "created": "2026-03-23T09:50:44.072687+00:00", "updated": "2026-03-25T14:42:17.366558+00:00", "vendors": ["axton", "axton$PRODUCT$wp-webauthn", "wordpress", "wordpress$PRODUCT$wordpress"]}
