CVE-2022-40764 has a CVSS score of 7.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2022-40764?

CVE-2022-40764 affects the following packages: snyk (npm), snyk-go-plugin (npm). Ecosystems affected: npm.

How do I fix CVE-2022-40764?

Update snyk to 1.996.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-40764 is resolved across your whole dependency graph.

How do I detect CVE-2022-40764 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for snyk. 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-2022-40764 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-2022-40764?

O3 pinpoints whether CVE-2022-40764 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-2022-40764 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2022-40764, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2022-40764?

CVE-2022-40764 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 40th 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.

When was CVE-2022-40764 published, and has it been updated?

CVE-2022-40764 was published on October 3, 2022 and was last updated on April 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.

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

Description

Snyk CLI before 1.996.0 allows arbitrary command execution, affecting Snyk IDE plugins and the snyk npm package. Exploitation could follow from the common practice of viewing untrusted files in the Visual Studio Code editor, for example. The original demonstration was with shell metacharacters in the vendor.json ignore field, affecting snyk-go-plugin before 1.19.1. This affects, for example, the Snyk TeamCity plugin (which does not update automatically) before 20220930.142957.
