Junie CLI and ZCode could run code from MCP servers declared in a cloned repo; only Junie is patched
CVE-2026-111091 (JetBrains Junie CLI, fixed in 26.8.3) and CVE-2026-88755 (Z.ai's ZCode, no known fix, public PoC) both let opening a crafted repository auto-start its workspace MCP servers, which over stdio are just commands, scored 7.8 High. Update Junie, avoid opening untrusted repos or PR branches in ZCode, and treat repo-local MCP and hook configs as code.
