CVE-2025-61775Network attack vector

Email flooding via reusable confirmation links

Published Oct 13, 2025 · Updated Oct 16, 2025

Resource exhaustion in Whimsies YATeam Vickey before 2025.10.0 allows remote attackers to send repeated confirmation emails. The email-confirmation handler accepts a still-unexpired verification link after the address is verified instead of rejecting the completed token. No authentication or user interaction is required, but the attacker must possess a valid unexpired link; the effect is unwanted email traffic without user-data exposure.
