What is CVE-2026-3350?

The Image Alt Text Manager plugin for WordPress contains a vulnerability that allows authenticated attackers with Author-level access and above to carry out Stored Cross-Site Scripting (XSS) attacks. This vulnerability arises from inadequate input sanitization and output escaping when the plugin dynamically generates image alt and title attributes using a DOM parser. As a result, attackers can inject arbitrary web scripts into pages, which will execute whenever a user visits the crafted page, potentially compromising user data and site integrity.
