{"id":"AZL-110091","summary":"CVE-2026-113732 affecting package python-virtualenv 20.36.1-6","details":"virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.2, FishActivator inherits ViaTemplateActivator.quote(), which uses POSIX shlex.quote() even though fish interprets backslashes and single quotes differently. An attacker-influenced environment path, --prompt, or VIRTUALENV_PROMPT value containing a backslash before a quote can therefore terminate the generated fish literal and execute command substitution when the user sources activate.fish. This issue is fixed in version 21.14.2.","modified":"2026-10-23T14:16:39.259172730Z","published":"2026-10-20T22:19:30Z","upstream":["CVE-2026-113732"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113732"}],"affected":[{"package":{"name":"python-virtualenv","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-virtualenv"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"20.36.1-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-110091.json"}}],"schema_version":"1.9.0"}
