Real — exploited in the wild

CISA confirms active exploitation. Treat scanner hits as true positives unless your specific version or config is unaffected.

CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:L/A:N

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.

    Field note · TruePositive EditorialCurated

    JQuery Cross-Site Scripting (XSS) Vulnerability — JQuery contains a persistent cross-site scripting (XSS) vulnerability. When passing maliciously formed, untrusted input enclosed in HTML tags, JQuery's DOM manipulators can execute untrusted code in the context of the user's browser. Listed in the CISA KEV catalog (added 2025-01-23) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~85%. Treat it as real and prioritize remediation over triage.

  • 0
    Remediation · TruePositive EditorialCurated

    Required action for JQuery JQuery: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. CISA set a federal remediation due date of 2025-02-13. After patching, verify the vulnerable path is no longer reachable before closing the finding.
