{"id":"UBUNTU-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.","modified":"2026-06-24T11:01:43.169056682Z","published":"2026-06-18T16:16:00Z","upstream":["CVE-2026-44691"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-44691"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-44691"}],"affected":[{"package":{"name":"eclipse","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/eclipse?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.8.1-8"],"ecosystem_specific":{"binaries":[{"binary_version":"3.8.1-8","binary_name":"eclipse"},{"binary_name":"eclipse-jdt","binary_version":"3.8.1-8"},{"binary_name":"eclipse-pde","binary_version":"3.8.1-8"},{"binary_name":"eclipse-platform","binary_version":"3.8.1-8"},{"binary_name":"eclipse-platform-data","binary_version":"3.8.1-8"},{"binary_version":"3.8.1-8","binary_name":"eclipse-rcp"},{"binary_name":"libequinox-osgi-java","binary_version":"3.8.1-8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44691.json"}},{"package":{"name":"eclipse","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/eclipse?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.8.1-10","3.8.1-11"],"ecosystem_specific":{"binaries":[{"binary_name":"eclipse","binary_version":"3.8.1-11"},{"binary_name":"eclipse-jdt","binary_version":"3.8.1-11"},{"binary_version":"3.8.1-11","binary_name":"eclipse-pde"},{"binary_version":"3.8.1-11","binary_name":"eclipse-platform"},{"binary_name":"eclipse-platform-data","binary_version":"3.8.1-11"},{"binary_version":"3.8.1-11","binary_name":"eclipse-rcp"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-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"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
