Claude Code flaws allow remote code execution and API key theft via untrusted repositories; three bugs fixed across 2025–2026 releases.
Claude Code Got Hacked — RCE & API Key Theft via Untrusted Repos
Yikes, Claude Code just got exposed. Three critical vulnerabilities let attackers execute remote code and steal API keys by exploiting untrusted repositories. Anthropic patched them across 2025–2026 releases, but this is a major red flag for AI-powered dev tools.
The flaws were discovered by security researchers and reported to Anthropic. They involve code injection and information disclosure weaknesses in Claude Code's handling of external repositories. Attackers could trick the system into running malicious code or leaking sensitive API keys, potentially compromising entire development environments.
- • Remote code execution (RCE) via untrusted repositories
- • API key exfiltration through information disclosure
- • Three distinct vulnerabilities patched in 2025–2026 releases
- • Affects Claude Code's repository integration features
- • High severity — could lead to full system compromise
Anthropic has released fixes across multiple versions. Users are urged to update immediately. This incident highlights the growing security challenges in AI-assisted development tools, where code generation meets real-world execution environments.
The vulnerabilities demonstrate how AI coding assistants can become attack vectors when they interact with external code sources. Security researchers warn that as these tools become more integrated into development workflows, their attack surface expands significantly.
