CVE-2024-11904 is a stored cross-site scripting vulnerability in the 코드엠샵 소셜톡 WordPress plugin, affecting all versions up to and including 1.2.0. The issue is due to improper neutralization of input in the 'msntt_add_plus_talk' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, and partial confidentiality and integrity impact.

An attacker with contributor-level access or higher can exploit this vulnerability to inject malicious scripts that execute in other users' browsers when they view the compromised pages. This can lead to partial confidentiality and integrity loss, such as theft of session tokens or manipulation of page content. There is no indication of availability impact. No known exploits in the wild have been reported so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit contributor-level access to trusted users only and consider disabling or removing the vulnerable shortcode if possible. Monitor for updates from the plugin vendor or WordPress security channels for an official patch.
