{"id":"UBUNTU-CVE-2023-28859","details":"redis-py before 4.4.4 and 4.5.x before 4.5.4 leaves a connection open after canceling an async Redis command at an inopportune time, and can send response data to the client of an unrelated request. (This could, for example, happen for a non-pipeline operation.) NOTE: the solutions for CVE-2023-28859 address data leakage across AsyncIO connections in general.","modified":"2026-05-20T16:13:32.533413623Z","published":"2023-03-26T19:15:00Z","upstream":["CVE-2023-28859"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-28859"},{"type":"REPORT","url":"https://github.com/redis/redis-py/pull/2641"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-28859"}],"affected":[{"package":{"name":"python-redis","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/python-redis?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.4-3"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-redis","binary_version":"4.3.4-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-28859.json"}},{"package":{"name":"python-redis","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/python-redis?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.4-4","5.2.1-1","6.1.0-1","6.1.0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"6.1.0-2","binary_name":"python3-redis"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-28859.json"}},{"package":{"name":"python-redis","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/python-redis?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.1.0-2","6.4.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-redis","binary_version":"6.4.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-28859.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
