CVE-2026-116537: Link Library WordPress plugin stored XSS in link_description

CVE-2026-116537 · Severity: high · CVSS 7.2 · Published 2026-11-07

The Link Library plugin for WordPress is used to display curated links on websites. An unauthenticated attacker can inject malicious scripts via the link_description field that execute in browsers of anyone viewing the page, potentially stealing credentials or defacing content. This requires the site administrator to enable a non-default setting that converts bracket syntax to HTML.

Vendors: WordPress.org.

How to fix

Disable the 'Convert [] to <> in Link Description and Notes' (use_html_tags) setting until an update is available; when this option is disabled, the bracket-to-angle-bracket conversion does not run and payloads cannot be reconstructed into executable HTML.

Technical details

Stored cross-site scripting (XSS) vulnerability in the 'link_description' parameter due to insufficient input sanitization and output escaping. When the 'Convert [] to <> in Link Description and Notes' (use_html_tags) setting is enabled, user input is converted from bracket notation to HTML angle brackets, allowing attackers to inject executable scripts. The vulnerability is network-accessible and requires no authentication, but depends on the non-default configuration option being active.
