{"id":"DEBIAN-CVE-2026-113723","details":"virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, caller-supplied prompt text can become executable syntax in the bash activation prompt. An attacker must influence the value passed to virtualenv, and a user must subsequently activate the environment and draw the prompt. This vulnerability is fixed in 21.14.9.","modified":"2026-10-23T16:02:44.308309056Z","published":"2026-10-20T20:17:18.967Z","upstream":["CVE-2026-113723"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-113723"}],"affected":[{"package":{"name":"python-virtualenv","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-virtualenv?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20.17.1+ds-1","20.19.0+ds-1","20.21.0+ds-1","20.23.0+ds-1","20.23.0+ds-2","20.24.1+ds-1","20.24.6+ds-1","20.24.6+ds-2","20.25.0+ds-1","20.25.0+ds-2","20.25.1+ds-1","20.26.1+ds-1","20.26.2+ds-1","20.26.6+ds-1","20.27.0+ds-1","20.28.0+ds-1","20.29.1+ds-1","20.29.3+ds-1","20.30.0+ds-1","20.30.0+ds-2","20.30.0+ds-3","20.31.2+ds-1","20.33.1+ds-1","20.34.0+ds-1","20.35.3+ds-1","20.35.4+ds-1","20.36.1+ds-1","20.38.0+ds-1","21.2.0+ds-1","21.2.4+ds-1","21.3.1+ds-1","21.4.1+ds-1","21.5.1+ds-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-113723.json"}},{"package":{"name":"python-virtualenv","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-virtualenv?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20.31.2+ds-1","20.31.2+ds-1+deb13u1","20.33.1+ds-1","20.34.0+ds-1","20.35.3+ds-1","20.35.4+ds-1","20.36.1+ds-1","20.38.0+ds-1","21.2.0+ds-1","21.2.4+ds-1","21.3.1+ds-1","21.4.1+ds-1","21.5.1+ds-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-113723.json"}},{"package":{"name":"python-virtualenv","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-virtualenv?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20.31.2+ds-1","20.33.1+ds-1","20.34.0+ds-1","20.35.3+ds-1","20.35.4+ds-1","20.36.1+ds-1","20.38.0+ds-1","21.2.0+ds-1","21.2.4+ds-1","21.3.1+ds-1","21.4.1+ds-1","21.5.1+ds-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-113723.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
