Comb","description":"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.","publishedAt":"2026-06-18T14:32:01.444Z","updatedAt":"2026-06-18T15:25:13.612Z","severity":{"score":6.7,"label":"Medium","version":"4.0","vector":"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","source":"eclipse"},"assigner":"eclipse","products":["Eclipse Foundation Eclipse Theia"],"affected":[{"vendor":"Eclipse Foundation","product":"Eclipse Theia","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"1.71.0","versionType":"semver"}],"repo":"https://github.com/eclipse-theia/theia"}],"references":["https://gitlab.eclipse.org/security/cve-assignment/-/work_items/115"],"weaknesses":["CWE-201","CWE-829"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/22xxx/CVE-2026-22551.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-22551","state":"PUBLISHED","datePublished":"2026-06-18T14:32:01.444Z","dateUpdated":"2026-06-18T15:25:13.612Z","assignerShortName":"eclipse","assignerOrgId":"e51fbebd-6053-4e49-959f-1b94eeb69a2c","dateReserved":"2026-05-22T07:47:58.210Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"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.
