{"id":"CVE-2026-47781","summary":"pdm: Project-Controlled `.pdm-plugins` Content Executes Before CLI Parsing","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.","aliases":["GHSA-qq6c-99pv-prvf","PYSEC-2026-2863"],"modified":"2026-08-06T03:48:17.628102201Z","published":"2026-08-04T18:42:23.036Z","related":["openSUSE-SU-2026:11124-1","openSUSE-SU-2026:21161-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-829","CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47781.json"},"references":[{"type":"WEB","url":"https://github.com/pdm-project/pdm/releases/tag/2.27.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47781.json"},{"type":"ADVISORY","url":"https://github.com/pdm-project/pdm/security/advisories/GHSA-qq6c-99pv-prvf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47781"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pdm-project/pdm","events":[{"introduced":"0"},{"fixed":"09c95b7842844f4e857c88f669e1c666db405c71"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.27.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["2.26.9","2.26.8","2.26.7","2.26.6","2.26.5","2.26.4","2.26.3","2.26.2","2.26.1","2.26.0","2.25.9","2.25.8","2.25.7","2.25.6","2.25.5","2.25.4","2.25.3","2.25.2","2.25.1","2.25.0","2.24.2","2.24.1","2.24.0","2.23.1","2.23.0","2.22.4","2.22.3","2.22.2","2.22.1","2.22.0","2.21.0","2.20.1","2.20.0.post1","2.20.0","2.19.3","2.19.2","2.19.1","2.19.0","2.18.2","2.18.1","2.18.0","2.17.3","2.17.2","2.17.1","2.17.0","2.16.1","2.16.0","2.15.4","2.15.3","2.15.2","2.15.1","2.15.0","2.14.0","2.13.3","2.13.2","2.13.1","2.13.0","2.12.4","2.12.3","2.12.2","2.12.1","2.12.0","2.11.2","2.11.1","2.11.0","2.10.4","2.10.3","2.10.2","2.10.1","2.10.0","2.9.3","2.9.2","2.9.1","2.9.0","2.8.2","2.8.1","2.8.0","2.8.0a2","2.8.0a1","2.8.0a0","2.7.4","2.7.3","2.7.2","2.7.1","2.7.0","2.6.1","2.6.0","2.5.3","2.5.2","2.5.1","2.5.0","2.5.0b0","2.4.9","2.4.8","2.4.7","2.4.6","2.4.5","2.4.4","2.4.3","2.4.2","2.4.1","2.4.0","2.3.4","2.3.3","2.3.2","2.3.1","2.3.0","2.2.1","2.2.0","2.1.5","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0","1.15.4","2.0.3","2.0.2","2.0.1","2.0.0","2.0.0b2","2.0.0b1","2.0.0a1","1.15.3","1.15.2","1.15.1","1.15.0","1.14.1","1.14.0","1.13.6","1.13.5","1.13.4","1.13.3","1.13.2","1.13.1","1.13.0.post0","1.13.0","1.12.8","1.12.7","1.12.6","1.12.5","1.12.4","1.12.3","1.12.2","1.12.1","1.12.0","1.11.3","1.11.2","1.11.1","1.11.0","1.10.3","1.10.2","1.10.1","1.10.0","1.9.0","1.8.5","1.8.4","1.8.3","1.8.2","1.8.1","1.8.0","1.7.2","1.7.1","1.7.0","1.6.4","1.6.3","1.6.2","1.6.1","1.6.0","1.5.3","1.5.2","1.5.1","1.5.0","1.5.0b1","1.5.0b0","1.4.5","1.4.4","1.4.3","1.4.2","1.4.1","1.4.0","1.3.4","1.3.3","1.3.2","1.3.1","1.3.0","1.2.0post1","1.2.0","1.1.0","1.0.0","1.0.0b2","1.0.0b0","0.12.3","0.12.2","0.12.1","0.12.0","0.11.0","0.10.2","0.10.1","0.10.0","0.9.2","0.9.1","0.9.0","0.8.7","0.8.6","0.8.5","0.8.4","0.8.3","0.8.2","0.8.1","0.8.0","0.7.1","0.7.0","0.6.5","0.6.4","0.6.3","0.6.2","0.6.1","0.6.0","0.5.0","0.4.2","0.4.1","0.4.0","0.3.2","0.3.1","0.3.0","0.2.6","0.2.5","0.2.4","0.2.3","0.2.2","0.2.1","0.2.0","0.1.2","0.1.1","0.1.0","0.0.6","0.0.5","0.0.4","0.0.3","0.0.2","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47781.json"}}],"schema_version":"1.8.0","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"}]}
