## Description

Audiobookshelf is a self-hosted audiobook and podcast server. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 2.32.0 of the Audiobookshelf web application that allows arbitrary JavaScript execution through malicious library metadata. Attackers with library modification privileges can execute code in victim users' browsers, potentially leading to session hijacking and data exfiltration. Version 2.32.0 contains a patch for the issue.
