Process crash via negative memory accounting
Published Mar 26, 2026 · Updated Mar 26, 2026
Resource consumption in Harttle LiquidJS before 10.25.1 allows remote attackers to crash the Node.js process with a crafted template. Range evaluation passes high minus low plus one to Limiter.use(), which accepts negative counts from reverse ranges and drives its memory-accounting base below zero. An application must enable memoryLimit and render attacker-controlled templates; later append and replace filters force V8 to flatten an oversized string and terminate the service process.
