{"id":"CVE-2026-44691","details":"In Eclipse Theia versions prior to 1.69.0, custom task definitions in workspace files (e.g. .theia/tasks.json, .vscode/tasks.json) could be executed without requiring workspace trust. An attacker could craft a malicious repository that, when cloned and opened in Theia, leads to execution of arbitrary commands with the user's privileges. In combination with AI chat features and a workspace .theia/settings.json that disabled tool confirmation, this could be triggered automatically by sending a message in the AI chat.","aliases":["GHSA-g9jw-92q7-g7fj"],"modified":"2026-07-08T08:13:29.714648617Z","published":"2026-06-18T14:35:25.486Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44691.json","cna_assigner":"eclipse","cwe_ids":["CWE-829"]},"references":[{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/116"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44691.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44691"},{"type":"PACKAGE","url":"https://github.com/eclipse-theia/theia"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-theia/theia","events":[{"introduced":"0"},{"fixed":"d9db3eac9a3426256ef1067878b96e8e3db43743"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"extracted_events":[{"introduced":"0"},{"fixed":"1.69.0"}],"cpe":"cpe:2.3:a:eclipse:theia:*:*:*:*:*:*:*:*"}}],"versions":["v1.68.0","v1.67.0","v1.66.0","v1.65.0","v1.64.0","v1.63.0","v1.62.0","v1.61.0","v1.60.0","v1.59.0","v1.58.0","v1.57.0","v1.55.0","v1.56.0","v1.54.0","v1.53.0","v1.52.0","v1.50.0","v1.49.0","v1.48.0","v1.47.0","v1.46.0","v1.45.0","v1.44.0","v1.43.0","v1.42.0","v1.41.0","v1.40.0","v1.39.0","v1.38.0","v1.37.0","v1.36.0","v1.35.0","v1.34.0","v1.33.0","v1.32.0","v1.31.0","v1.30.0","v1.29.0","v1.28.0","v1.27.0","v1.26.0","v1.25.0","v1.24.0","v1.23.0","v1.22.1","v1.22.0","v1.21.0","v1.20.0","v1.17.0","v1.16.0","v1.15.0","v1.14.0","v1.13.0","1.13.0","v1.12.0","v1.11.0","v1.10.0","v1.9.0","v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0","v0.16.0","v0.15.0","v0.14.0","v0.13.0","v0.12.0","v0.11.0","v0.10.0","v0.9.0","v0.8.0","v0.7.0","v0.6.0","v0.5.0","v0.4.0","v0.3.19","v0.3.18","v0.3.17","v0.3.16","v0.3.15","v0.3.14","v0.3.13","v0.3.12","v0.3.11","v0.3.10","v0.3.9","v0.3.8","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.1","v0.1.0","0.0.1-alpha.2","0.0.1-alpha.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44691.json"}}],"schema_version":"1.7.5","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"}]}
