How severe is GHSA-vrw9-g62v-7fmf?

No CVSS score has been assigned to GHSA-vrw9-g62v-7fmf yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-vrw9-g62v-7fmf?

GHSA-vrw9-g62v-7fmf affects the following packages: csvtojson (npm). Ecosystems affected: npm.

How do I fix GHSA-vrw9-g62v-7fmf?

Update csvtojson to 2.0.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vrw9-g62v-7fmf is resolved across your whole dependency graph.

How do I detect GHSA-vrw9-g62v-7fmf in my npm dependencies?

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

How do I mitigate GHSA-vrw9-g62v-7fmf 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-vrw9-g62v-7fmf actively exploited in the wild?

No public exploit code has been indexed for GHSA-vrw9-g62v-7fmf 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.

What is the EPSS score for GHSA-vrw9-g62v-7fmf?

GHSA-vrw9-g62v-7fmf has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 24th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-vrw9-g62v-7fmf?

GHSA-vrw9-g62v-7fmf is classified as CWE-1321 (CWE-1321). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-vrw9-g62v-7fmf published, and has it been updated?

GHSA-vrw9-g62v-7fmf was published on September 24, 2025 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Exploitation Status

Proof-of-concept exploit code exists

CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

Description

The csvtojson package, a tool for converting CSV data to JSON with customizable parsing capabilities, contains a prototype pollution vulnerability in versions prior to 2.0.10. This issue arises due to insufficient sanitization of nested header names during the parsing process in the parser_jsonarray component. When processing CSV input containing specially crafted header fields that reference prototype chains (e.g., using proto syntax), the application may unintentionally modify properties of the base Object prototype. This vulnerability can lead to denial of service conditions or unexpected behavior in applications relying on unmodified prototype chains, particularly when untrusted CSV data is processed. The flaw does not require user interaction beyond providing a maliciously constructed CSV file.
