CVE-2025-11570
MEDIUMCVE-2025-11570 is a medium-severity (CVSS 4.6) Cross-site Scripting (XSS) vulnerability. O3 Security confirms whether CVE-2025-11570 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Versions of the package drupal-pattern-lab/unified-twig-extensions from 0.0.0 are vulnerable to Cross-site Scripting (XSS) due to insufficient filtering of data. **Note:** This is…
Description
Versions of the package drupal-pattern-lab/unified-twig-extensions from 0.0.0 are vulnerable to Cross-site Scripting (XSS) due to insufficient filtering of data.
Note: This is exploitable only if the code is executed outside of Drupal; the function is intended to be shared between Drupal and Pattern Lab.
The package drupal-pattern-lab/unified-twig-extensions is unmaintained, the fix for this issue exists in version 1.1.1 of drupal/unified_twig_ext
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2025-11570 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2025-11570 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-11570. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
