Push-notification interception and modification via certificate-validation failure
Published May 12, 2026 · Updated May 12, 2026
Improper certificate validation in Kura Sushi Official App 2.0.11 through 3.9.10 allows man-in-the-middle attackers to read or alter notifications. EPG has not disclosed which certificate property or validation step the push-notification connection fails to check. Exploitation requires control of the network path, such as a malicious wireless LAN access point; the reported impact is limited to reading or modifying push-notification traffic.
