LiquidJS has Exponential Memory Amplification through its replace_first Filter $& Pattern

Summary The replacefirst filter in LiquidJS uses JavaScript's String.prototype.replace which interprets $& as a backreference to the matched substring. The filter only charges memoryLimit for the input string length, not the amplified output. An attacker can achieve exponential memory amplificati...

Allocation of Resources Without Limits or Throttling

Overview liquidjs is an A simple, expressive, safe and Shopify compatible template engine in pure JavaScript. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the replacefirst function. An attacker can exhaust system memory and disru...

PT-2026-28163

Name of the Vulnerable Software and Affected Versions LiquidJS versions prior to 10.25.1 Description LiquidJS is susceptible to a denial of service condition due to insufficient memory limit enforcement within the replace first filter. The filter utilizes JavaScript's String.prototype.replace,...
