CVE-2026-113715
Description
A flaw was found in virtualenv. When creating virtual environments, the tool fails to properly sanitize destination pathnames containing line-breaking characters before processing configuration files. An attacker who influences the target path can exploit this flaw to inject unauthorized settings into the environment's configuration. This can weaken environment isolation or cause Python to load standard library files from an untrusted directory.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
