The SEO Keywords WordPress plugin (seomantis) contains a reflected XSS vulnerability via the 'google_error' parameter due to improper input neutralization during web page generation. This allows unauthenticated attackers to inject arbitrary JavaScript that executes when a victim interacts with a malicious link. The vulnerability affects all plugin versions up to 1.1.3. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity, with no impact on availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected website, potentially enabling theft of user credentials, session hijacking, or other malicious actions limited to the scope of the reflected XSS. There is no indication of availability impact. The vulnerability requires user interaction and does not require authentication.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or removing the SEO Keywords plugin or implementing web application firewall (WAF) rules to block malicious payloads targeting the 'google_error' parameter. Avoid clicking on suspicious links that could trigger the vulnerability.
