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. Vendor/CNA’s CVSS 4.0 assessment rates confidentiality and integrity impact as none; availability impact as high.
