DescriptionCVE.org

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in plugin/YPTWallet/view/saveBalance.php that allows attackers to set arbitrary wallet balances by relying only on session cookies without token validation. Attackers can craft a malicious webpage that, when loaded by an administrator, submits a POST request to modify any user's wallet balance to any value.

AnalysisAI

Cross-site request forgery in AVideo's YPTWallet plugin enables unauthenticated attackers to set arbitrary wallet balances for any user by tricking an authenticated administrator into loading a malicious webpage. The vulnerable endpoint plugin/YPTWallet/view/saveBalance.php relies exclusively on session cookies for request authorization with no CSRF token validation, meaning a forged POST request is accepted as legitimate whenever an admin's browser submits it. …
