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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"harttle","product":"liquidjs","versions":[{"version":"< 10.26.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-18T19:05:03.703365Z","id":"CVE-2026-44645","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-400"}]}],"references":[{"url":"https://github.com/harttle/liquidjs/commit/5b9c3469085e01c79e2d0af28e2a13f730e1793d","source":"security-advisories@github.com"},{"url":"https://github.com/harttle/liquidjs/releases/tag/v10.26.0","source":"security-advisories@github.com"},{"url":"https://github.com/harttle/liquidjs/security/advisories/GHSA-8xx9-69p8-7jp3","source":"security-advisories@github.com"},{"url":"https://github.com/harttle/liquidjs/security/advisories/GHSA-8xx9-69p8-7jp3","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
