Through a Scanner Falsely: When AI-reported Critical Vulnerabilities Aren’t

Automation in security is essential due to the overwhelming nature of alerts and backlogs compared to attackers, but it can generate harmful noise without proper context. A case study with an AI-based code reviewer illustrates this, where it identified a "Host Header Injection: CRITICAL VULNERABILITY" that was, in fact, non-exploitable due to existing safeguards like infrastructure and browser constraints. This highlights the difference between vulnerabilities and actual exploitable threats, stressing the importance of context in security assessments. False positives from AI tools can erode trust and credibility in security teams, causing unnecessary workloads and frustration among developers. To improve the situation, security leaders should focus on integrating AI solutions that offer immediate, in-line fixes rather than filling backlogs with non-critical issues, and they should customize tools to better distinguish between genuine threats and low-risk vulnerabilities. This approach could help reduce alert fatigue and improve the efficacy of security measures, while AI's real promise lies in its ability to enhance security processes without overwhelming developers with false alarms.
