Answer in brief
CVE-2026-75858 records a Unknown severity vulnerability in CodeWhale rlm_eval before 0.8.64 Remote Code Execution. The current sources do not mark it as known exploited. The current feed maps Hmbown/CodeWhale (generic), Hmbown/CodeWhale (generic). Check affected ranges and fixed versions before updating.

CodeWhale (packages codewhale / codewhale-tui) versions >= 0.8.41 and < 0.8.64 contain a remote code execution vulnerability in the rlm_eval tool. The tool's approval_requirement() returns ApprovalRequirement::Auto, which the engine treats as 'never prompt,' causing arbitrary model-supplied Python code to run in a python3 interpreter without consulting the user's configured --approval-policy and without any approval prompt or audit step. An attacker can induce the agent to execute arbitrary code via prompt injection in untrusted content the agent reads (a web page, fetched URL, repository file, or MCP tool result); the companion rlm_open tool can stage such content. Code runs on the user's machine at the user's privilege level. Fixed in 0.8.64.
