The SiteOrigin Widgets Bundle plugin for WordPress contains a stored XSS vulnerability in its Image Grid widget due to improper neutralization of input during web page generation (CWE-79). Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript that executes in the context of other users viewing the injected page. This vulnerability affects all versions up to 1.62.2. No patch or official fix information is provided in the available data.

An attacker with contributor-level access or higher can inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to theft of user credentials, session hijacking, or other actions performed with the victim's privileges. The vulnerability does not affect availability but impacts confidentiality and integrity of user data.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the Image Grid widget if possible. Monitor for updates from the vendor or plugin maintainers regarding patches or temporary mitigations.
