CVE-2026-75857
HighCVSS 7.0Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
CodeWhale versions >= 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 0.8.64.
Risk Assessment
An attacker can execute commands in the context of an approved process, potentially leading to privilege escalation, data theft, or system integrity compromise.
Recommendation
Update CodeWhale to version 0.8.64 or later, which includes a fix. Limit agent usage to trusted content and monitor long-running interactive sessions.
