Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2026-50540)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to execute arbitrary code on the host.

The vulnerability exists due to improper input validation in the kata-runtime load_config function when processing the io.katacontainers.config_path pod annotation. A remote user can supply a crafted configuration file path to execute arbitrary code on the host.

Exploitation requires the ability to set pod annotations and access to a host filesystem path containing an attacker-controlled TOML configuration file.
