CVE-2024-11774 is a stored cross-site scripting vulnerability in the Outdooractive Embed WordPress plugin's 'list2go' shortcode. The issue is due to improper neutralization of input during web page generation, specifically insufficient input sanitization and output escaping of user-supplied shortcode attributes. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript that executes in the context of users visiting the injected page. This vulnerability affects all versions up to 1.5 of the plugin. The CVSS 3.1 base score is 6.4 (medium), with network attack vector, low attack complexity, privileges required at the low level, no user interaction needed, and impacts confidentiality and integrity with no availability impact.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to unauthorized actions such as session hijacking or data theft. The impact affects confidentiality and integrity but does not affect availability. There are no known exploits in the wild at this time.

No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory channels for updates. Until a fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Outdooractive Embed plugin if possible to prevent exploitation.
