{"id":"AZL-112589","summary":"CVE-2026-113718 affecting package python-virtualenv 20.36.1-9","details":"virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, POSIX xonsh activation quote() uses repr() to write printable non-ASCII prompt or destination data into UTF-8 activate.xsh, while xonsh can read that script using $XONSH_ENCODING. Under a legacy multibyte codec such as GBK or Big5, a UTF-8 trail byte can consume the backslash before an adjacent quote, allowing the literal to close and attacker-influenced statements to execute when the user sources the generated script. This issue is fixed in version 21.14.9.","modified":"2026-11-03T14:18:14.025601049Z","published":"2026-10-20T20:17:18Z","upstream":["CVE-2026-113718"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113718"}],"affected":[{"package":{"name":"python-virtualenv","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-virtualenv"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"20.36.1-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-112589.json"}}],"schema_version":"1.9.2"}
