{"id":"CVE-2026-33285","state":"PUBLISHED","title":"LiquidJS: memoryLimit Bypass through Negative Range Values Leads to Process Crash","description":"LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, LiquidJS's `memoryLimit` security mechanism can be completely bypassed by using reverse range expressions (e.g., `(100000000..1)`), allowing an attacker to allocate unlimited memory. Combined with a string flattening operation (e.g., `replace` filter), this causes a V8 Fatal error that crashes the Node.js process, resulting in complete denial of service from a single HTTP request. Version 10.25.1 patches the issue.","publishedAt":"2026-03-26T00:34:25.169Z","updatedAt":"2026-03-28T02:08:05.711Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["harttle liquidjs"],"affected":[{"vendor":"harttle","product":"liquidjs","versions":[{"version":"< 10.25.1","status":"affected"}]}],"references":["https://github.com/harttle/liquidjs/security/advisories/GHSA-9r5m-9576-7f6x","https://github.com/harttle/liquidjs/commit/95ddefc056a11a44d9e753fd47a39db2c241e578"],"weaknesses":["CWE-20","CWE-400"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33285.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33285","state":"PUBLISHED","datePublished":"2026-03-26T00:34:25.169Z","dateUpdated":"2026-03-28T02:08:05.711Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-18T18:55:47.426Z"},"containers":{"cna":{"title":"LiquidJS: memoryLimit Bypass through Negative Range Values Leads to Process Crash","descriptions":[{"lang":"en","value":"LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript.
