## What is CVE-2026-58195?

CVE-2026-58195 is a high-severity vulnerability in ruvnet agentic-flow, published on 17 Jul 2026. 

### Official description

Agentic-Flow is an AI agent orchestration platform. Prior to 2.0.14, agentic-flow MCP server tools in src/mcp/standalone-stdio.ts, src/mcp/fastmcp/servers/claude-flow-sdk.ts, src/mcp/fastmcp/servers/stdio-full.ts, src/mcp/fastmcp/servers/http-streaming-updated.ts, src/mcp/fastmcp/servers/http-sse.ts, src/mcp/fastmcp/servers/poc-stdio.ts, src/mcp/fastmcp/tools/agent/{execute,list,parallel}.ts, src/mcp/fastmcp/tools/swarm/orchestrate.ts, and src/mcp/fastmcp/tools/hooks/pretrain.ts interpolated attacker-influenceable tool parameters such as agent, task, name, language, and agentdb directly into shell command strings passed to execSync(), allowing arbitrary OS command execution with the privileges of the MCP server user. This issue is fixed in version 2.0.14.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

```text
Check this codebase for CVE-2026-58195 and fix it if it is affected.

What it is: CVE-2026-58195 is a high-severity vulnerability in ruvnet agentic-flow, published on 17 Jul 2026. 
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-58195 exists.

Affected packages and fixed versions:
- agentic-flow (npm): affected all versions; fixed in 2.0.14
- agentic-flow (npm): affected all versions; fixed in 2.0.14

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
