{"cve":"CVE-2026-44688","nvd":{"published":"2026-06-18T16:16:53.977","modified":"2026-10-26T11:10:00.157","status":"Analyzed","description":"In Eclipse Theia versions prior to 1.71.0, the AI chat agent processed workspace file and directory names as part of its prompt context without distinguishing them from system instructions. An attacker could craft a malicious repository with adversarial directory or file names that, when analyzed by the AI agent, would cause the agent to follow attacker-controlled instructions (indirect prompt injection). Combined with other AI chat features available in untrusted workspaces, this enabled attack chains leading to data exfiltration via Markdown image rendering or arbitrary command execution via task definitions.","cvss_v4":{"vector":"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","score":8.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-829"],"references":["https://gitlab.eclipse.org/security/cve-assignment/-/work_items/113"],"products":["eclipse:theia"],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-44688","score":0.00507,"percentile":0.43,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-3jww-hxqj-wfq2","url":"https://osv.dev/vulnerability/GHSA-3jww-hxqj-wfq2","summary":"[Eclipse Theia] Indirect Prompt Injection via Adversarial Workspace File and Directory Names in AI Chat","modified":"2026-09-10T03:50:55.306656325Z","packages":[{"ecosystem":"npm","name":"@theia/ai-chat-ui","purl":"pkg:npm/%40theia/ai-chat-ui","ranges":["<1.71.0"],"fixed":["1.71.0"]},{"ecosystem":"npm","name":"@theia/ai-chat","purl":"pkg:npm/%40theia/ai-chat","ranges":["<1.71.0"],"fixed":["1.71.0"]},{"ecosystem":"npm","name":"@theia/ai-claude-code","purl":"pkg:npm/%40theia/ai-claude-code","ranges":["<1.71.0"],"fixed":["1.71.0"]},{"ecosystem":"npm","name":"@theia/ai-code-completion","purl":"pkg:npm/%40theia/ai-code-completion","ranges":["<1.71.0"],"fixed":["1.71.0"]},{"ecosystem":"npm","name":"@theia/ai-core","purl":"pkg:npm/%40theia/ai-core","ranges":["<1.71.0"],"fixed":["1.71.0"]},{"ecosystem":"npm","name":"@theia/ai-editor","purl":"pkg:npm/%40theia/ai-editor","ranges":["<1.71.0"],"fixed":["1.71.0"]},{"ecosystem":"npm","name":"@theia/ai-ide","purl":"pkg:npm/%40theia/ai-ide","ranges":["<1.71.0"],"fixed":["1.71.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
