InversePrompt: Turning Claude Against Itself, One Prompt at a Time - cymulate.com/blog/cve-2025-5… - By @EladBeber @ @Cymulateltd
As Anthropic’s Claude Code gains traction as a powerful AI coding assistant, it promises developers a safe and streamlined way to build with Claude’s capabilities. But what happens when the same assistant meant to enforce restrictions unknowingly reveals how to bypass them?
During Anthropic’s Research Preview phase, I discovered two high-severity vulnerabilities in Claude Code, which were quickly addressed by the team. These issues allowed me to escape its intended restrictions and execute unauthorized actions, all with Claude’s own help.
By turning the tool inward and exploring how it interprets and validates inputs, I uncovered flaws that led to:
- Path restriction bypass.
- Code execution via command injection.
Both are exploitable through simple prompt crafting. These findings highlight the risks of blindly trusting LLM-powered developer tools, especially when the same system meant to enforce the rules can also be used to break them.

The Hidden Risk in AI-Generated Code: A Silent Backdoor
A newly discovered attack method exploits AI-driven coding assistants like GitHub Copilot and Cursor, manipulating rule files to introduce silent backdoors into generated code.
How the Attack Works
1️⃣ Rules File Poisoning – Attackers inject hidden malicious instructions into AI rule files, altering how code is generated.
2️⃣ Unicode Obfuscation – Invisible characters conceal harmful payloads from human reviewers but remain readable to AI models.
3️⃣ Semantic Hijacking – Subtle manipulations mislead AI models into producing insecure code, bypassing security best practices.
4️⃣ Persistent Compromise – Once a poisoned rule file enters a repository, it infects future AI-generated code, spreading via forks and dependencies.
Mitigation Strategies
🔍 Audit Rule Files – Review AI configuration files for hidden Unicode characters and anomalies.
🛡 Apply AI-Specific Validation – Treat rule files with the same scrutiny as executable code.
📊 Monitor AI Outputs – Detect unexpected modifications, external dependencies, or security risks.
