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.
