Service interruption via unaccounted pop array cloning
Published Jul 8, 2026 · Updated Jul 8, 2026
Resource exhaustion in Harttle LiquidJS before 10.27.1 allows remote attackers to interrupt a service via attacker-influenced arrays. The pop filter in src/filters/array.ts clones the entire input array without charging its length to the configured memoryLimit budget. Exploitation requires memoryLimit, a template that applies pop, and attacker-influenced array length; heap exhaustion can crash the Node.js process.
