Prior to version 9.2.0561, the Python omni-completion script in python3complete.vim for Vim with the +python3 interpreter enabled (and the legacy pythoncomplete.vim for builds with the +python interpreter) executes the import and from statements found in the current buffer through Python's import machinery. Because the buffer's working directory is on sys.path, opening a hostile .py file with a sibling Python package and invoking omni-completion runs that package's top-level code as the editing user. This issue has been patched in version 9.2.0561.","published_at":"2026-06-11T18:32:32.722000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.3,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-94","CWE-95","CWE-829"],"nvd_references":["https://github.com/vim/vim/security/advisories/GHSA-52mc-rq6p-rc7c","https://github.com/vim/vim/commit/4b850457e12e1a678dd209f2868154f7553cbf8d","https://github.com/vim/vim/releases/tag/v9.2.0561"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:49.088205Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"A","value_label":"Active"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"vim","vendor_name":"vim","product_slug":"vim","product_name":"vim","version_start":"< 9.2.0561","version_start_inclusive":true,"version_end":"< 9.2.0561","version_end_inclusive":true,"cpe23_uri":"cve5:vim:vim:< 9.2.0561:< 9.2.0561"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/vim/vim/security/advisories/GHSA-52mc-rq6p-rc7c","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/vim/vim/commit/4b850457e12e1a678dd209f2868154f7553cbf8d","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/vim/vim/releases/tag/v9.2.0561","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-11T18:32:32.722000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"}]}
