CVE-2026-92581— AVideo through 29.0 Like Counter Desynchronization via Array Parameter

Quick assessment

Affected
WWBN AVideo
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 AVideo 29.0 及更早版本中， 方法在验证之前，直接对原始请求值执行计数器运算，这使得数组类型的参数能够导致已存储的投票与计数器不同步。经过身份验证的攻击者可以先发送数组类型的“点赞”参数，随后再发送普通请求，从而将视频的点赞数任意变为负值；这种数据不一致会持续存在于非规范化的计数器中，直到进行手动修复。

Vulnerability Title
AVideo through 29.0 Like Counter Desynchronization via Array Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
In AVideo through 29.0, Like::__construct() performs counter arithmetic on raw request values before validation, allowing array-typed parameters to desynchronize stored votes from counters. Authenticated attackers can send array-typed like parameters followed by ordinary requests to drive video like counts arbitrarily negative, with the corruption persisting in the denormalized counter until manual repair.
