The Dynamic Widget Content WordPress plugin suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the widget content field in the Gutenberg editor sidebar does not properly sanitize or escape user input, allowing authenticated users with Contributor or higher privileges to inject malicious scripts. These scripts execute in the context of any user who views the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 1.3.6. No patch or fix has been documented in the provided data.

An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages via the widget content field. These scripts execute in the browsers of users who visit the affected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not impact availability and requires authentication, but it affects confidentiality and integrity to a limited extent as reflected by the CVSS vector (C:L/I:L/A:N). There are no known exploits in the wild at this time.

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 Dynamic Widget Content plugin if possible. Monitor official channels for updates or patches addressing this vulnerability.
