Description

Scriban before 7.0.0 (affected versions <= 6.6.0) contains a denial-of-service vulnerability in which the LimitToString safety limit (default 1MB) can be bypassed because ObjectToString resets the per-call length counter (_currentToStringLength) on every top-level call and StringBuilderOutput enforces no cumulative output-size limit. An attacker who can supply a template can render a near-limit string repeatedly in a loop, allocating approximately 1GB of memory and causing an out-of-memory condition that crashes the host application.
