Which packages are affected by GHSA-58q2-9x27-h2jm?

GHSA-58q2-9x27-h2jm affects the following packages: solspace/craft-freeform (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-58q2-9x27-h2jm?

Update solspace/craft-freeform to 4.1.30 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-58q2-9x27-h2jm is resolved across your whole dependency graph.

How do I detect GHSA-58q2-9x27-h2jm in my Packagist dependencies?

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

How do I mitigate GHSA-58q2-9x27-h2jm if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-58q2-9x27-h2jm actively exploited in the wild?

No public exploit code has been indexed for GHSA-58q2-9x27-h2jm 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

Summary

Freeform plugin v4.1.29 uses vulnerable Axios ^1.7.7 allowing unauthenticated attackers to crash servers via malicious data: URIs causing memory exhaustion (CVE-2025-58754).

Freeform version: 4.1.29 Craft CMS version: 4.16.8

Impact

When Axios runs on Node.js and is given a URL with the data: scheme, it does not perform HTTP. Instead, its Node http adapter decodes the entire payload into memory (Buffer/Blob) and returns a synthetic 200 response. This path ignores maxContentLength / maxBodyLength (which only protect HTTP responses), so an attacker can supply a very large data: URI and cause the process to allocate unbounded memory and crash (DoS), even if the caller requested responseType: 'stream'.
