How severe is CVE-2022-24725?

CVE-2022-24725 has a CVSS score of 6.2/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2022-24725?

CVE-2022-24725 affects the following packages: shescape (npm). Ecosystems affected: npm.

How do I fix CVE-2022-24725?

Update shescape to 1.5.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-24725 is resolved across your whole dependency graph.

How do I detect CVE-2022-24725 in my npm dependencies?

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

How do I mitigate CVE-2022-24725 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2022-24725 actively exploited in the wild?

Yes. There are 2 known exploit references for CVE-2022-24725, including 2 in-the-wild exploitations 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-2022-24725?

CVE-2022-24725 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th 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 CVE-2022-24725?

CVE-2022-24725 is classified as Information Exposure (CWE-200), OS Command Injection (CWE-78). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2022-24725 published, and has it been updated?

CVE-2022-24725 was published on March 3, 2022 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

The issue allows for exposure of the home directory on Unix systems when using Bash with the escape or escapeAll functions from the shescape API with the interpolation option set to true. Other tested shells, Dash and Zsh, are not affected.

const cp = require("child_process");
const shescape = require("shescape");

const payload = "home_directory=~";
const options = { interpolation: true };
console.log(cp.execSync(`echo ${shescape.escape(payload, options)}`));
// home_directory=/home/user

Depending on how the output of shescape is used, directory traversal may be possible in the application using shescape.

Patches

The issue was patched in v1.5.1.

Workarounds

Manually escape all instances of the tilde character (~) using arg.replace(/~/g, "\\~").
