KEVMEDIUM 6.1EPSS 83.8%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 13 February 2025). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

Description

In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
