CVE-2026-15117 is a high-severity use-after-free vulnerability in the Payments component of Google Chrome. In affected versions prior to 150.0.7871.115, improper object lifetime handling in payment-related processing can leave a dangling reference that is subsequently reused, resulting in heap corruption. The issue can be triggered by a remote attacker using a crafted HTML page and a specially constructed payment workflow, provided the victim performs specific user-interface gestures during the interaction. The vulnerability affects Chrome’s browser-side payment functionality and is classified by Chromium as High severity.
