CVE-2026-29955
High 8.8
In plain English
A high-severity code injection in the affected software. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 2.2% (higher than 82% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code.
Official description
The `/registercrd` endpoint in KubePlus 4.14 in the kubeconfiggenerator component is vulnerable to command injection. The component uses `subprocess.Popen()` with `shell=True` parameter to execute shell commands, and the user-supplied `chartName` parameter is directly concatenated into the command string without any sanitization or validation. An attacker can inject arbitrary shell commands by crafting a malicious `chartName` parameter value.
