{"id":"UBUNTU-CVE-2026-114608","details":"Pylint is a static code analyser for Python. From 0.15.2 until 4.0.9, Pylint stores module statistics in predictable files under PYLINT_HOME and loads those files with pickle.load on a later run. An attacker who can write to a shared, group-writable, or otherwise untrusted cache directory can replace a stats cache with crafted serialized data, causing arbitrary code to execute with the privileges of the user who next runs Pylint. The default per-user cache is not normally writable by another user. This issue is fixed in version 4.0.9.","modified":"2026-10-27T04:17:45.367221980Z","published":"2026-10-26T00:00:00Z","upstream":["CVE-2026-114608"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-114608"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-114608"},{"type":"REPORT","url":"https://github.com/pylint-dev/pylint/commit/58c87cffca9de2b3e89aa07b89686cbc90cfea2d"},{"type":"REPORT","url":"https://github.com/pylint-dev/pylint/commit/5b241f66318220e9ba7b21ca631fbfe8e77682ca"},{"type":"REPORT","url":"https://github.com/pylint-dev/pylint/releases/tag/v4.0.9"},{"type":"REPORT","url":"https://github.com/pylint-dev/pylint/security/advisories/GHSA-22qq-2fwx-7p67"}],"affected":[{"package":{"name":"pylint","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/pylint?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.1-3ubuntu1","1.4.4-1ubuntu1","1.5.2-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.5.2-1ubuntu1","binary_name":"pylint"},{"binary_name":"pylint3","binary_version":"1.5.2-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/pylint?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.2-0ubuntu4","1.8.1-1","1.8.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pylint","binary_version":"1.8.3-1"},{"binary_name":"pylint3","binary_version":"1.8.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/pylint?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.2-3","2.4.4-1","2.4.4-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.4-2","binary_name":"pylint"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/pylint?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.2-3ubuntu1","2.11.1-1","2.12.2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.12.2-1","binary_name":"pylint"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/pylint?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.17.4-1","3.0.3-1","3.0.3-2"],"ecosystem_specific":{"binaries":[{"binary_name":"pylint","binary_version":"3.0.3-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/pylint?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.5-1","4.0.6-1","4.0.8-1"],"ecosystem_specific":{"binaries":[{"binary_version":"4.0.8-1","binary_name":"pylint"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/pylint?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.4-2","4.0.4-1","4.0.5-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pylint","binary_version":"4.0.5-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114608.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
