0 CVE-2026-22813 is a critical cross-site scripting (XSS) vulnerability in the anomalyco OpenCode AI coding agent's markdown renderer. The renderer inserts arbitrary HTML into the DOM without sanitization or Content Security Policy (CSP), allowing JavaScript execution on the localhost web interface. This enables attackers who can influence the LLM response in a chat session to execute malicious scripts in the context of the http://localhost:4096 origin. The vulnerability affects OpenCode versions prior to 1.1.10 and requires no authentication but does require user interaction to trigger. Although no known exploits are currently in the wild, the high CVSS score of 9.4 reflects the severe impact on confidentiality, integrity, and availability. The issue is fixed in version 1.1.
