CVE-2025-13637 is a low-severity security vulnerability in the Downloads component of Google Chrome. In Chrome versions prior to 143.0.7499.41, an inappropriate implementation allowed a remote attacker to bypass browser download protections by serving a crafted HTML page and inducing the target user to perform specific user-interface gestures. The issue is described as a protection bypass rather than a memory-safety flaw, and the available information indicates the weakness resides in how download-related security controls were enforced within the Downloads feature.
