Npm · Check-Peer-Dependencies · CVE-2026-15033
**Name of the Vulnerable Software and Affected Versions**
christopherthielen check-peer-dependencies versions prior to 4.3.5
**Description**
An OS command injection flaw exists in the `peerDependencies` component within the `dist/packageUtils.js` file. The issue resides in the `shelljs.exec()` function, which allows a remote attacker to execute arbitrary operating system commands.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
As a temporary workaround, restrict the use of the `shelljs.exec()` function in the `dist/packageUtils.js` file to minimize the risk of exploitation.
