CVE-2020-23363Public exploitNetwork attack vector

Unauthorized state changes via forged browser requests

Published May 9, 2023 · Updated Jan 29, 2025

Cross-site request forgery in Verytops Verydows all versions allows remote attackers to alter application data through a victim's browser. The upstream report does not identify a specific endpoint; state-changing requests accept a logged-in victim's session without verifying request intent. A victim must visit attacker-controlled content while authenticated, and resulting actions are limited to the victim's privileges; public evidence does not substantiate the broader code-execution claim.
