CVE-2025-69262
HIGHCVE-2025-69262 is a high-severity (CVSS 7.5) OS Command Injection vulnerability in pnpm. O3 Security confirms whether CVE-2025-69262 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
pnpmnpmDescription
pnpm is a package manager. Versions 6.25.0 through 10.26.2 have a Command Injection vulnerability when using environment variable substitution in .npmrc configuration files with tokenHelper settings. An attacker who can control environment variables during pnpm operations could achieve Remote Code Execution (RCE) in build environments. This issue is fixed in version 10.27.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pnpm. 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.
Fix
Update pnpm to 10.27.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-69262 is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether CVE-2025-69262 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-69262. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
