critical Tenable Self-Hosted Container Security Plugin ID 436745

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenCode is an open source AI coding agent. The markdown renderer used for LLM responses will insert
 arbitrary HTML into the DOM. There is no sanitization with DOMPurify or even a CSP on the web interface to
 prevent JavaScript execution via HTML injection. This means controlling the LLM response for a chat
 session gets JavaScript execution on the http://localhost:4096 origin. This vulnerability is fixed in
 1.1.10. (CVE-2026-22813)
