What is CVE-2026-73062?

Scriban versions 3.0.0 through 7.2.0 exhibit a denial of service vulnerability due to improper handling of memory allocation in the array multiplication operator. This allows attackers to input a large integer multiplier into a template, resulting in excessive memory consumption that can lead to resource exhaustion and degrade system availability. The lack of LoopLimit enforcement and overflow-safe arithmetic checks exacerbates the risk, making it crucial for users to address this vulnerability promptly.
