Description

Versions of the package jquery-validation before 1.20.0 are vulnerable to Cross-site Scripting (XSS) in the showLabel() function, which may take input from a user-controlled placeholder value. This value will populate a message via $.validator.messages in a user localizable dictionary.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for jquery-validation, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update jquery-validation to 1.20.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rrj2-ph5q-jxw2 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
