ServiceNow Fixes Critical AI Platform Flaw Exploited to Mimic Legitimate Users

In a significant development for AI-augmented enterprise security, ServiceNow patched a critical vulnerability in its AI Platform — tracked under CVE-2025-12420 — that previously allowed attackers to impersonate legitimate users without authentication. Discovered late in 2025 but publicly addressed this week, the flaw exemplified how emerging AI-powered interfaces can unintentionally introduce fresh attack surfaces if not fortified with robust identity and access controls. Security researchers praised the quick response from ServiceNow’s security engineering teams and noted how this case is likely to fuel increased R&D investment into secure AI integrations, particularly around authentication, session handling, and privilege boundaries within autonomous systems. For defenders, this patch highlights a growing trend where AI-enabled interfaces — while boosting productivity — require the same, if not greater, scrutiny traditionally reserved for low-level protocol implementations or kernel-level bugs.
