Summary
Zod 4.6.5 Uncontrolled Resource Consumption via Array Validation
Details

Zod schema-validation library through 4.6.5, fixed in commit e06a510, contains an uncontrolled resource consumption vulnerability that allows attackers to exhaust memory by submitting a large array to an application using an array schema without a length constraint. Attackers can exploit the handleArrayResult parse logic in $ZodArray, which accumulates every validation issue for each failing element with no cap or early termination, causing the process to allocate excessive issue objects and crash due to out-of-memory conditions.
