How do I fix CVE-2024-35226?

Update smarty/smarty to 5.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-35226 is resolved across your whole dependency graph.

How do I detect CVE-2024-35226 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for smarty/smarty. 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.

How do I mitigate CVE-2024-35226 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2024-35226?

O3 pinpoints whether CVE-2024-35226 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-35226 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-35226 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

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

Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. In affected versions template authors could inject php code by choosing a malicious file name for an extends-tag. Sites that cannot fully trust template authors should update asap. All users are advised to update. There is no patch for users on the v3 branch. There are no known workarounds for this vulnerability.
