Which packages are affected by GHSA-vrhm-gvg7-fpcf?

GHSA-vrhm-gvg7-fpcf affects the following packages: @sveltejs/kit (npm). Ecosystems affected: npm.

How do I fix GHSA-vrhm-gvg7-fpcf?

Update @sveltejs/kit to 2.52.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vrhm-gvg7-fpcf is resolved across your whole dependency graph.

How do I detect GHSA-vrhm-gvg7-fpcf in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @sveltejs/kit. 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 GHSA-vrhm-gvg7-fpcf 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 GHSA-vrhm-gvg7-fpcf?

O3 pinpoints whether GHSA-vrhm-gvg7-fpcf 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 GHSA-vrhm-gvg7-fpcf actively exploited in the wild?

No public exploit code has been indexed for GHSA-vrhm-gvg7-fpcf 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.

Description

Versions of @sveltejs/kit prior to 2.52.2 with remote functions enabled can be vulnerable to memory exhaustion. Malformed form data can cause the server process to crash due to excessive memory allocation, resulting in denial of service.

Only applications using both experimental.remoteFunctions and form are vulnerable.
