Versions 10.25.1 and later contain the fix and are not affected.", "description_and_impact": "LiquidJS, a template engine used by Shopify and GitHub Pages, contains a flaw in its memoryLimit enforcement. By supplying a reverse range expression such as (100000000..1) the engine allocates unlimited memory. When this is combined with a string flattening operation like the replace filter, the V8 engine throws a fatal error that crashes the Node.js process. The result is a complete denial of service that can be triggered by a single HTTP request. The weakness is rooted in improper input validation (CWE\u201120) and uncontrolled resource consumption (CWE\u2011400).", "risk_and_exploitability": "The flaw carries a CVSS score of 7.5, indicating a high severity. While EPSS data is not available, the vulnerability is not listed in the CISA KEV catalog, suggesting it has not yet been widely exploited in the wild. Attackers can trigger the exploit through standard HTTP requests that include malicious template code, allowing them to crash the server process without additional privileges. The impact is limited to the targeted instance, but repeated crashes can cause sustained service disruption."}}}}, "created": "2026-03-26T11:30:53.032114+00:00", "updated": "2026-03-26T12:08:54.743367+00:00", "vendors": ["harttle", "harttle$PRODUCT$liquidjs"]}
