CVE-2026-75857: falha de alta gravidade em Hmbown CodeWhale

CodeWhale versions >= 0.3.10 and < 0.8.64 (published as deepseek-tui >= 0.3.10 and < 0.8.41 on npm and 0.3.10 through 0.8.41 on crates.io, and as codewhale / codewhale-tui >= 0.8.41 and < 0.8.64) contain a vulnerability in the exec_shell_interact (alias exec_interact) tool, whose approval_requirement returns ApprovalRequirement::Auto. This overrides the default Required approval for code-executing tools, so LLM-controlled stdin is written into an already-approved long-running interactive shell (e.g., a python3 -i REPL, mysql, ssh, or sudo -i session) without any approval prompt. An attacker who can inject instructions via untrusted content the agent ingests (a fetched page, MCP result, or repo file) can cause commands to run at the privilege level of that approved process. Fixed in codewhale / codewhale-tui 0.8.64; the deprecated deepseek-tui crate has no fixed release.
