CVE-2026-1397 is a stored cross-site scripting vulnerability in the peacefulqode PQ Addons – Creative Elementor Widgets WordPress plugin, affecting all versions up to 1.0.0. The issue is due to improper neutralization of input (CWE-79) in the html_tag parameter of the PQ Section Title widget, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users viewing the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 score of 6.4, reflecting a medium severity with network attack vector, low attack complexity, and no user interaction required.

An attacker with contributor-level or higher access can exploit this vulnerability to inject malicious scripts into pages via the html_tag parameter. These scripts execute in the browsers of users who visit the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not impact availability and requires authenticated access, limiting its scope to users with some level of trust on the site.

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 removing or disabling the PQ Section Title widget if feasible. Monitor for plugin updates from peacefulqode that address this vulnerability.
