CVE-2024-13700 is a stored cross-site scripting vulnerability in the Embed Swagger UI plugin for WordPress, affecting all versions up to 1.0.0. The issue stems from improper neutralization of input (CWE-79) in the plugin's 'wpsgui' shortcode, where user-supplied attributes are not properly sanitized or escaped before being output in web pages. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of users visiting the compromised pages. The vulnerability has a CVSS 3.1 base score of 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, required privileges, no user interaction, and partial impact on confidentiality and integrity without availability impact.

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

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Embed Swagger UI plugin if possible to prevent exploitation.
