{"id":"DEBIAN-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":"2026-10-23T18:05:16.764066095Z","published":"2026-10-22T17:16:58.750Z","upstream":["CVE-2026-114608"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-114608"}],"affected":[{"package":{"name":"pylint","ecosystem":"Debian:12","purl":"pkg:deb/debian/pylint?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.16.2-2","2.17.4-1","3.0.3-1","3.0.3-2","3.1.0-1","3.1.0-2","3.2.2-1","3.2.2-2","3.2.6-1","3.2.7-1","3.3.1-1","3.3.1-2","3.3.3-1","3.3.3-2","3.3.4-1","3.3.4-2","4.0.4-1","4.0.5-1","4.0.6-1","4.0.8-1","4.0.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Debian:13","purl":"pkg:deb/debian/pylint?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.4-1","3.3.4-2","4.0.4-1","4.0.5-1","4.0.6-1","4.0.8-1","4.0.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114608.json"}},{"package":{"name":"pylint","ecosystem":"Debian:14","purl":"pkg:deb/debian/pylint?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.4-1","3.3.4-2","4.0.4-1","4.0.5-1","4.0.6-1","4.0.8-1","4.0.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114608.json"}}],"schema_version":"1.9.0","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/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"}]}
