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.

AnalysisAI
Remote code execution in CodeWhale (packages codewhale and codewhale-tui) versions 0.8.41 through 0.8.63 allows an attacker to execute arbitrary Python code on the victim's machine by exploiting a hardcoded approval bypass in the rlm_eval built-in tool. The tool's approval_requirement() method returned ApprovalRequirement::Auto, causing the engine to silently skip user approval prompts regardless of the operator's configured --approval-policy, enabling prompt injection attacks through any external content the agent reads. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running a CodeWhale agent in versions 0.8.41 through 0.8.63 in a workflow that processes externally-controlled or untrusted content - specifically content reachable via the rlm_open tool, a fetched URL, a third-party repository file, or an MCP tool result. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.5 (AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) accurately models the threat: the attack executes locally on the victim's machine, requires no attacker privileges (PR:N) to plant the malicious payload in external content, and delivers full code execution impact (VC:H/VI:H/VA:H) once the victim's agent processes the injected content (UI:P). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker publishes a repository README or web page containing a carefully crafted prompt injection payload instructing the CodeWhale agent to call rlm_eval with attacker-specified Python code - for example, code that exfiltrates local SSH keys or environment variables to an attacker-controlled endpoint. When a developer running a vulnerable CodeWhale version directs the agent to summarize or analyze that external resource, the agent's rlm_open tool stages the content, the injected instruction is interpreted as a legitimate model directive, and rlm_eval executes the Python payload silently at the user's OS privilege level with no approval prompt or log entry. … |
| Remediation | Upgrade to CodeWhale version 0.8.64, which resolves the vulnerability by changing RlmEvalTool::approval_requirement() to return ApprovalRequirement::Required and declaring ToolCapability::RequiresApproval, ensuring all code execution through rlm_eval is gated on user confirmation consistent with the configured --approval-policy. … Detailed patch versions, workarounds, and compensating controls in full report. |
