Chainlit Enables Arbitrary File Read And SSRF

Zafran disclosed two vulnerabilities in Chainlit in November, and Chainlit released a patched 2.9.4 release a month later. The flaws (CVE-2026-22218 and CVE-2026-22219) allow arbitrary file reads and SSRF, risking exposure of environment variables, API keys, cloud credentials, and authentication token forgery in internet-facing deployments used by financial, energy, and academic organizations. Users should update to Chainlit 2.9.4 immediately.
Scoring Rationale
High credibility and directly actionable patch; impact limited by scope to Chainlit deployments rather than all AI frameworks.
