While an allowlist restricts the command name (e.g. `git`, `pandoc`, `grep`), the argument string is concatenated with the command and passed to `child_process.spawn` with the `shell: true` option, allowing shell metacharacters in the arguments to bypass the allowlist. An attacker with JavaScript execution in the renderer (e.g. via XSS or a malicious plugin) can execute arbitrary shell commands with the privileges of the Logseq process, leading to remote code execution on the host.\nWhile only version v0.10.15 was tested and confirmed as vulnerable, status of other versions is unknown since this issue was not addressed by a patch.","published_at":"2026-06-09T13:23:41.892000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":8.7,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-78"],"nvd_references":["https://cert.pl/en/posts/2026/06/CVE-2026-9279/","https://logseq.com/"],"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":"2026-06-28T23:31:12.150571Z"},"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":"L","value_label":"Local"},{"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":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"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":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"H","value_label":"High"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"H","value_label":"High"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"logseq","vendor_name":"logseq","product_slug":"logseq","product_name":"logseq","version_start":"0","version_start_inclusive":true,"version_end":"0.10.15","version_end_inclusive":true,"cpe23_uri":"cve5:logseq:logseq:0:0.10.15"}],"exploit_refs":[],"news":[],"references":[{"url":"https://cert.pl/en/posts/2026/06/CVE-2026-9279/","source_type":"MISC","tags":[]},{"url":"https://logseq.com/","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-09T13:23:41.892000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:56:27.543306Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:56:27.543306Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:56:27.543306Z","label":"CVSS score revised","source":"cvelistv5"}]}
