Summary
A vulnerability was detected in publint up to 0.1.4. This impacts the function child_process.exec of the file src/node/pack.js of the component package-manager Command Handler.
The manipulation results in os command injection. Attacking locally is a requirement.
The exploit is now public and may be used. The patch is identified as adf2d9a09945fc98c85a2520a89f441d78b2dbd8.
It is advisable to implement a patch to correct this issue. The project maintainer explains: "I think it's very rare for someone to use this package with untrusted input".
This allows the attacker to execute arbitrary commands on the system where publint is running, potentially leading to unauthorized system access or data manipulation. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).
Weakness: CWE-78. Red Hat lists Red Hat Enterprise Linux 10; Red Hat Hardened Images as not affected.
