{"id":"UBUNTU-CVE-2026-22551","details":"In Eclipse Theia versions prior to 1.71.0, the AI chat rendered Markdown image tags from AI responses, triggering HTTP requests to arbitrary external URLs without restriction. Combined with prompt injection in a malicious workspace, an attacker could induce the AI agent to construct image URLs encoding sensitive information from the workspace or conversation context, exfiltrating it to attacker-controlled servers. The workspace trust enforcement introduced in v1.71.0 mitigates the documented attack chain by disabling AI features in untrusted workspaces.","modified":"2026-06-24T11:01:29.013227652Z","published":"2026-06-18T16:16:00Z","upstream":["CVE-2026-22551"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-22551"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-22551"}],"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_name":"eclipse","binary_version":"3.8.1-8"},{"binary_version":"3.8.1-8","binary_name":"eclipse-jdt"},{"binary_name":"eclipse-pde","binary_version":"3.8.1-8"},{"binary_version":"3.8.1-8","binary_name":"eclipse-platform"},{"binary_name":"eclipse-platform-data","binary_version":"3.8.1-8"},{"binary_name":"eclipse-rcp","binary_version":"3.8.1-8"},{"binary_version":"3.8.1-8","binary_name":"libequinox-osgi-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-22551.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_version":"3.8.1-11","binary_name":"eclipse"},{"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_version":"3.8.1-11","binary_name":"eclipse-platform-data"},{"binary_name":"eclipse-rcp","binary_version":"3.8.1-11"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-22551.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:N/VA:N/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:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
