Zafran Labs disclosed two critical Chainlit vulnerabilities (CVE-2026-22218 and CVE-2026-22219) that allow arbitrary file reads and SSRF-driven retrieval of internal resources, respectively; researchers showed these can be chained to exfiltrate secrets and enable cloud lateral movement. The flaws affect internet-facing deployments, were fixed in Chainlit 2.9.4 (latest 2.9.6), and administrators are urged to update immediately to prevent credential and data exposure.
