DeepSeek TUI: run_tests Tool Enables RCE via Malicious Repository Without Approval

CVE-2026-45311GHSA-wx44-2q6h-j6p8

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (deepseek-tui 0.8.23; deepseek-tui-cli 0.8.23; deepseek-tui 0.8.23), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary The runtests tool executes cargo test in the workspace with ApprovalRequirement::Auto, meaning it runs without any user approval prompt. The source code explicitly states this design choice: cargo test compiles and executes arbitrary code: test binaries, build.rs build scripts, and proc macros. While auto-approving test execution is a deliberate design choice, it creates an inconsistency in the security boundary. However, in a malicious repository, test code can execute arbitrary shell commands, exfiltrate credentials, or establish persistence with zero approval. The attack is amplified by AGENTS.md (auto-loaded into the system prompt), which can instruct the model to run tests proactively at session start. PoC Step 1 — Create a malicious Rust repo: Cargo.toml: [package] name = "cool-library" version = "0.1.0" edition = "2021" src/lib.rs: pub fn add(a: i32, b: i32) - i32 { a + b } tests/integrationtest.rs: use coollibrary::add; #[test] fn testadd() { asserteq!(add(2, 3), 5);…

# Patch Next advisory brief: CVE-2026-45311

Advisory: DeepSeek TUI: run_tests Tool Enables RCE via Malicious Repository Without Approval
IDs: CVE-2026-45311, GHSA-wx44-2q6h-j6p8
Record: https://patchnext.com/advisories/cve-2026-45311 (revision 3, source checked 26 Oct 2026, 12:53 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: deepseek-tui 0.8.23; deepseek-tui-cli 0.8.23; deepseek-tui 0.8.23. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm deepseek-tui: affected >= 0.3.0, < 0.8.23; fixed in 0.8.23
- crates.io deepseek-tui-cli: affected >= 0.3.0, < 0.8.23; fixed in 0.8.23
- crates.io deepseek-tui: affected >= 0.3.0, < 0.8.23; fixed in 0.8.23

## Suggested inspection (read-only)
- `npm ls deepseek-tui --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- crates.io deepseek-tui-cli: check the installed version with your package manager.
- crates.io deepseek-tui: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on deepseek-tui, deepseek-tui-cli.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
