{"id":"DEBIAN-CVE-2026-47781","details":"PDM is a Python package and dependency manager. In versions up to and including 2.26.9, PDM automatically loads project-local plugins from a .pdm-plugins directory during initialization, allowing an attacker-controlled file in an untrusted repository checkout to execute arbitrary Python code before any command is parsed. This happens because load_plugins() runs during Core.init() and adds .pdm-plugins via site.addsitedir(), which processes .pth files and immediately executes any line beginning with import, so the code runs with the privileges of the user invoking pdm and even a benign command such as pdm --version triggers it (making the impact strongest in CI, automation, and privileged contexts). The issue is fixed in version 2.27.0.","modified":"2026-09-09T08:47:26.745766493Z","published":"2026-08-04T19:16:51.240Z","upstream":["CVE-2026-47781"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-47781"}],"affected":[{"package":{"name":"pdm","ecosystem":"Debian:12","purl":"pkg:deb/debian/pdm?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1+ds1-1","2.2.1+ds1-2","2.20.0.post1+ds1-1","2.20.0.post1+ds1-2","2.20.1+ds1-1","2.20.1+ds1-2","2.23.1-1","2.23.1-2","2.23.1-3","2.23.1-4","2.26.2-1","2.26.6-1","2.27.0-1","2.28.0-1","2.28.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47781.json"}},{"package":{"name":"pdm","ecosystem":"Debian:13","purl":"pkg:deb/debian/pdm?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.20.1+ds1-2","2.23.1-1","2.23.1-2","2.23.1-3","2.23.1-4","2.26.2-1","2.26.6-1","2.27.0-1","2.28.0-1","2.28.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47781.json"}},{"package":{"name":"pdm","ecosystem":"Debian:14","purl":"pkg:deb/debian/pdm?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.27.0-1"}]}],"versions":["2.20.1+ds1-2","2.23.1-1","2.23.1-2","2.23.1-3","2.23.1-4","2.26.2-1","2.26.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47781.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/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"}]}
