CVE-2026-8887 Details
Description
The Listen Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'listen' shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user supplied attributes (src, start, end) in the listenEmbedJS() function, which are echoed inside a single-quoted HTML attribute without escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
A stored cross-site scripting vulnerability has been identified in the Listen Shortcode plugin for WordPress, affecting versions through 1.0. The issue arises from inadequate input sanitization and output escaping of user-supplied attributes in the 'listen' shortcode. Specifically, the 'src', 'start', and 'end' attributes are processed in the listenEmbedJS() function and echoed within a single-quoted HTML attribute without proper escaping. This flaw allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which are executed when users access the compromised page.
There is no known patch available for this vulnerability. Users are advised to review the vulnerability details and consider uninstalling the affected plugin.
