Description détaillée

LangChat through commit 2a6285a contains a missing authentication vulnerability that allows unauthenticated remote attackers to access REST controllers because no Sa-Token interceptor is registered.

CVE-2026-96620

Claude Agent SDK is a Python SDK for Claude Code. Prior to 0.2.121, the resume option is passed to the Claude CLI as a separate token without validation, so a dash-leading value is parsed as an independent CLI flag. An attacker can inject the --mcp-config flag to define a stdio MCP server, causing arbitrary command execution at CLI startup outside the SDK permission controls. The issue is exploitable when an application passes untrusted input as the session ID to resume. This issue is fixed in version 0.2.121.
