Denial Of Service (DoS)

LiquidJS is vulnerable to Denial Of Service DoS. The vulnerability is due to the pop array filter allocating a full clone of the input array without enforcing the configured memory limit, which allows an attacker to exhaust memory and cause a denial-of-service condition by rendering templates wit...

GHSA-G357-X5C3-C72P LiquidJS: `pop` filter bypasses `memoryLimit` accounting that its array-filter siblings enforce

CVE-2026-41311

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.7, a circular block reference in % layout % / % block % causes an infinite recursive loop, consuming all available memory 4GB and crashing the Node.js process with FATAL ERROR: JavaScript he...

Path Traversal

LiquidJS is vulnerable to Path Traversal. The vulnerability is due to the path-based check for partial and layout roots, where a symlink to a file outside the allowed root can be loaded if it is placed inside an allowed partials or layouts directory, and attackers can exploit this by placing...

CVE-2026-39859

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.3, liquidjs 10.25.0 documents root as constraining filenames passed to renderFile and parseFile, but top-level file loads do not enforce that boundary. A Liquid instance configured with an empty...

CVE-2026-33287 LiquidJS has Exponential Memory Amplification through its replace_first Filter $& Pattern

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, the replacefirst filter in LiquidJS uses JavaScript's String.prototype.replace which interprets $& as a back reference to the matched substring. The filter only charges memoryLimit for th...

GHSA-6Q5M-63H6-5X4V 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...
