Based on 0 community responses
After a vulnerability like CVE-2025-55182 is patched, it's crucial to audit codebases for potential backdoors or malicious code injected during the exposure window. While patching removes the vulnerability, it doesn't remove any malicious code that may have been introduced. Companies, especially high-value targets like fintech and healthcare, should consider thorough audits to ensure their codebases haven't been compromised. An AST-based scanner, like the one open-sourced by the author, can significantly speed up this process by checking for Indicators of Compromise.
Key Takeaways
Patching a vulnerability doesn't remove malicious code that may have been injected
High-value targets should consider thorough audits post-patching
Using automated tools like AST-based scanners can significantly reduce audit time
