python3.13-virtualenv: virtualenv is a tool for creating isolated virtual python environments
CVE-2026-115586 is fixed in 2 products on 1 platform, first by ALAS2023-2026-3409, released November 10, 2026. It is not reported as exploited. Patch Radar priority: High.
virtualenv is a tool for creating isolated virtual python environments. From 21.14.9 until 21.14.13, the bash bin/activate script can copy an attacker-controlled --prompt value into PS1 without escaping dollar signs or backticks when both promptvars and POSIX mode are disabled during activation. Re-enabling promptvars, running set -o posix, or starting an interactive child bash that inherits the exported PS1 can then expand command substitution in the stored VIRTUAL_ENV_PROMPT value and execute commands as the user who activates the environment. This issue is fixed in version 21.14.13.
