CVE-2022-25948 WRITEUP MEDIUM WRITEUP
liquidjs < 10.0.0 - Information Exposure via Prototype Property Leak
The package liquidjs before 10.0.0 are vulnerable to Information Exposure when ownPropertyOnly parameter is set to False, which results in leaking properties of a prototype. Workaround For versions 9.34.0 and higher, an option to disable this functionality is provided.
CVSS 5.3
CVE-2026-34166 WRITEUP LOW WRITEUP
LiquidJS <10.25.3 replace Filter - Memory Limit Bypass
LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.3, the replace filter in LiquidJS incorrectly accounts for memory usage when the memoryLimit option is enabled. It charges str.length + pattern.length + replacement.length bytes to the memory limiter, but the actual output from str.split(pattern).join(replacement) can be quadratically larger when the pattern occurs many times in the input string. This allows an attacker who controls template content to bypass the memoryLimit DoS protection with approximately 2,500x amplification, potentially causing out-of-memory conditions. This vulnerability is fixed in 10.25.3.
CVSS 3.7
CVE-2026-33287 WRITEUP HIGH WRITEUP
LiquidJS has Exponential Memory Amplification through its replace_first Filter $& Pattern
LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, the `replace_first` filter in LiquidJS uses JavaScript's `String.prototype.replace()` which interprets `$&` as a back reference to the matched substring. The filter only charges `memoryLimit` for the input string length, not the amplified output. An attacker can achieve exponential memory amplification (up to 625,000:1) while staying within the `memoryLimit` budget, leading to denial of service. Version 10.25.1 patches the issue.
