Description

Scriban before 7.5.3 contains a resource exhaustion vulnerability that allows untrusted template authors to exhaust memory and CPU because builtins like math.format, regex.replace and string.escape skip the LimitToString allocation guard. Attackers can submit small templates using huge format precision specifiers, shared-structure array comparison, BigInteger multiplication or exponential function recursion that ignore LoopLimit and CancellationToken, crashing or stalling multi-tenant hosts.
