Until patched, this is only a concern on Linux systems where virtualenv creates POSIX console script launchers in attacker-influenced directory paths \u2014 non-POSIX platforms including Windows are unaffected \u2014 so restrict and audit who can specify virtual environment destination paths, ensure paths do not contain shell metacharacters or exceed 127 bytes, and regenerate existing launchers. As a compensating measure, log suspicious execve syscalls and command invocations resulting from command substitution evaluation using the Linux audit subsystem, confine the actions and access of commands executed by the compromised launcher process using SELinux in enforcing mode, restrict the privileges and capabilities inherited by commands spawned during launcher execution using SELinux confined user mappings, detect anomalous process trees and shell executions spawned upon script launcher invocation using EDR agents, and detect unexpected shell execution and child process spawning from script launcher paths using Falco eBPF runtime security. These controls limit blast radius and contain exploitation, but they do not fix the underlying improper-quoting command injection defect \u2014 apply the upstream patch to fully remediate.\nHighest-impact CME: CME-1307 Command Injection Prevention (No Shell Invocation) (high)"}, "name": "CVE-2026-113722", "package_state": [{"cpe": "cpe:/a:redhat:openshift_lightspeed:1",
