SlowMist founder Yu Xian reposted a thread on X about potential poisoning attack risks tied to Claude Code and published his own analysis covering Grok Build CLI and Claude Code CLI. According to the analysis, Grok Build CLI does not apply a single, consistent security model across its code paths. Different trust assumptions in different paths may open gaps that attackers can exploit. A malicious project configuration file could let an attacker run arbitrary commands without the user realizing it, then steal API keys, cloud credentials, or take control of a local device.
Researchers also built a test environment and found that on macOS, if Claude Code is affected, running a specific test command can trigger the local Calculator app to open. That result was presented as evidence of a potential command execution risk. If such an attack succeeds, the fallout could extend beyond local execution. The analysis says attackers may steal API keys for AI services including Claude and OpenAI, causing billing losses, obtain credentials for AWS, Alibaba Cloud, and Tencent Cloud to access servers and data, tamper with code repositories to implant backdoors, or use the compromised local machine as a pivot into an enterprise internal network. The related vulnerability is said to have existed for one year.
ChainCatcher reported that SlowMist founder Yu Xian reposted an X thread about potential poisoning attack risks involving Claude Code and published an analysis of attack details tied to Grok Build CLI and Claude Code CLI.
Inconsistent trust assumptions highlighted in Grok Build CLI
Yu Xian said Grok Build CLI does not have a unified security mechanism. Different code paths rely on different trust assumptions, and those gaps may give attackers a way in. Through a malicious project configuration file, an attacker may execute arbitrary commands without the user noticing, then steal API keys, cloud credentials, or gain control of the local device.
Test environment showed a potential command execution risk
Researchers built a test environment and found that on macOS, if Claude Code is affected, running a specific test command can trigger the local Calculator app to launch. The result was presented as proof of a potential command execution issue.
Possible impact if the attack succeeds
The analysis said a successful attack could let attackers steal API keys for AI services such as Claude and OpenAI, leading to account billing losses. It could also expose cloud service credentials for AWS, Alibaba Cloud, and Tencent Cloud, giving access to servers and data. Beyond that, attackers may tamper with code repositories to implant backdoors or use the local device as a stepping stone to attack an enterprise's internal network.
The related vulnerability has reportedly existed for one year.
