CVE-2026-93535: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in wppool Dark Mode – Improve Accessibility with AI Powered Dark Theme

CVE-2026-93535 is a stored Cross-Site Scripting vulnerability in the Dark Mode – Improve Accessibility with AI Powered Dark Theme WordPress plugin by wppool. The flaw arises from insufficient sanitization and escaping of the 'icon_light' shortcode attribute, allowing authenticated attackers with Contributor-level privileges or above to inject arbitrary web scripts. These scripts execute in the context of users who access the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions from 0 up to and including 5.3.17.

An attacker with Contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages. These scripts execute in the browsers of users who view the infected pages, potentially compromising user sessions and data confidentiality. The vulnerability does not affect availability and requires authentication with low privileges, but the impact on confidentiality and integrity is low to medium.

No official patch or fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users and consider disabling or removing the plugin if possible.
