{"cve":"CVE-2026-44645","nvd":{"published":"2026-06-17T23:17:03.607","modified":"2026-10-25T23:10:00.167","status":"Deferred","description":"LiquidJS is a Shopify/GitHub Pages compatible template engine written in pure JavaScript. In versions 10.25.7 and below, the renderLimit option can be fully bypassed by a {% for %} (or {% tablerow %}) tag whose body is empty. The renderLimit option is documented in docs/source/tutorials/dos.md as the mechanism that \"mitigates this by limiting the time consumed by each render() call.\" The per-iteration time check is reached only when the body contains at least one template node, so a template such as {%- for i in (1..N) -%}{%- endfor -%} iterates the full collection without ever consulting renderLimit. With a configured renderLimit of 50 ms, a single parseAndRenderSync call has been observed to consume 2.26 seconds (~45× over the limit) and scales linearly with N up to memoryLimit, allowing a low-privileged template author to wedge an event-loop thread for an attacker-chosen duration. Deployments that rely on a finite renderLimit for DoS protection (common in multi-tenant template-authoring environments) can still be forced by a single crafted template to monopolize a Node.js event-loop worker for attacker-controlled time, potentially stalling in-flight requests, with availability impact only. This issue has been fixed in version 10.26.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-400"],"references":["https://github.com/harttle/liquidjs/commit/5b9c3469085e01c79e2d0af28e2a13f730e1793d","https://github.com/harttle/liquidjs/releases/tag/v10.26.0","https://github.com/harttle/liquidjs/security/advisories/GHSA-8xx9-69p8-7jp3","https://github.com/harttle/liquidjs/security/advisories/GHSA-8xx9-69p8-7jp3"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-44645","score":0.00317,"percentile":0.24429,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8xx9-69p8-7jp3","url":"https://osv.dev/vulnerability/GHSA-8xx9-69p8-7jp3","summary":"LiquidJS has a renderLimit DoS guard bypass via empty `{% for %}` body","modified":"2026-09-10T03:50:46.304208031Z","packages":[{"ecosystem":"npm","name":"liquidjs","purl":"pkg:npm/liquidjs","ranges":["<=10.25.7"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
