Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Impact

Users with access to a form's settings can include malicious Twig code into fields that support Twig. These might be the Submission Title or the Success Message. This code will then be executed upon creating a submission, or rendering the text.

This is listed as low-medium severity due to requiring control panel access to edit a form's settings.

Patches

This has been fixed in Formie 2.1.6. Users should ensure they are running at least this version.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update verbb/formie to 2.1.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-35191 is resolved across your whole dependency graph.

  3. Workarounds

    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.
