CVE-2025-7811 is a stored cross-site scripting vulnerability in the StreamWeasels YouTube Integration plugin for WordPress, affecting all versions up to and including 1.4.0. The flaw exists because the plugin fails to properly sanitize and escape the 'data-uuid' attribute, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users who access the compromised pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and no user interaction required beyond authentication.

An attacker with contributor-level access or higher can exploit this vulnerability to inject and execute arbitrary JavaScript in the browsers of users who view the affected pages. This can lead to information disclosure or manipulation of user sessions. The vulnerability does not impact availability and requires authentication, limiting its scope. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — no official fix or patch links are currently available. Users should monitor the vendor's advisory channels for updates and apply any forthcoming patches promptly. Until a fix is released, restrict contributor-level access to trusted users only and consider removing or disabling the StreamWeasels YouTube Integration plugin if possible.
