Frequently Asked Questions

About CVE-2026-45618 and LiquidJS Vulnerability

What is CVE-2026-45618 and how does it affect LiquidJS?

CVE-2026-45618 is a critical remote code execution (RCE) vulnerability in LiquidJS, the Node.js implementation of Shopify’s Liquid template language. Versions prior to 10.26.0 allow unauthenticated, remote attackers to submit specially crafted templates that escape the intended sandbox and execute arbitrary code on the host. This vulnerability carries a CVSS v3.1 score of 10.0 (critical) and can lead to full compromise of confidentiality, integrity, and availability on affected systems. For details, see NIST NVD and GitHub Advisory. Note: Only LiquidJS versions prior to 10.26.0 are affected.

Which versions of LiquidJS are affected by CVE-2026-45618?

All versions of LiquidJS prior to 10.26.0 are affected by CVE-2026-45618. Any application, CMS, email templating system, or Node.js service that embeds LiquidJS as a direct or transitive dependency and renders untrusted template input is at risk. Note: Upgrading to version 10.26.0 or later is required to mitigate this vulnerability.

How can organizations mitigate CVE-2026-45618 in LiquidJS?

To mitigate CVE-2026-45618, organizations should immediately upgrade LiquidJS to version 10.26.0 or later. If immediate patching is not possible, do not render any Liquid templates containing attacker-controlled or untrusted content, audit all entry points that pass external input into LiquidJS’s parseAndRender/render functions, and add strict input validation or temporarily disable those features. Isolate template-rendering processes and monitor logs for anomalous Liquid syntax patterns. Note: These are temporary measures; full mitigation requires upgrading LiquidJS.

How can I check if my organization is exposed to CVE-2026-45618?

IONIX offers a free exposure report that maps all assets using LiquidJS, identifies potentially exposed assets to CVE-2026-45618, and confirms verified exploitable assets. Request a report at ionix.io/request-a-scan. Note: Exposure confirmation requires asset-level validation; not all instances of LiquidJS are exploitable.

IONIX Platform Capabilities for Zero-Day and CVE Response

How does IONIX detect and validate exposure to new zero-days like CVE-2026-45618?

IONIX continuously maps the entire external attack surface using multi-factor discovery methods, including DNS analysis, certificate mapping, and metadata inspection. For zero-days, IONIX analyzes dozens of threat intelligence feeds, applies AI to evaluate exploitability, and filters vulnerabilities by attacker-centric criteria (internet reachability, authentication requirements, active exploitation). IONIX then transforms real-world PoCs into safe, non-intrusive test payloads and executes validations only on assets that match the risk profile. This workflow enables rapid, actionable mitigation. Note: Validation is limited to externally reachable assets; internal-only exposures require additional controls.

What is Preemptive Exposure Mitigation (PEM) and how does IONIX deliver it?

Preemptive Exposure Mitigation (PEM) is IONIX's approach to not just discovering exposures, but validating which ones are exploitable and mitigating them before attackers can act. IONIX operates across the CTEM lifecycle: DISCOVER, VALIDATE, PRIORITIZE, MITIGATE, and VERIFY. The platform commits to a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation in the same window (Live Exposure Defense). Note: PEM focuses on external exposures; internal asset management is not included.

How does IONIX prioritize and route remediation for validated exposures?

IONIX routes validated exposure results through integrations with ticketing (Jira, ServiceNow), SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This process shortens mean time to remediation (MTTR) and enables teams to act with confidence. Note: Remediation prioritization depends on accurate asset inventory and integration setup.

What integrations does IONIX support for zero-day and CVE response workflows?

IONIX integrates with Jira, ServiceNow, Splunk, Microsoft Sentinel, Cloudflare WAF, Slack (via RSS), Wiz, Prisma Cloud, and any SIEM via documented API. These integrations enable automated ticket creation, alerting, and workflow orchestration for validated exposures. For a full list, see IONIX integration documentation. Note: Integration setup may require coordination with IT and security operations teams.

New CVE Detected

CVE-2026-45618 – Remote Code Execution (RCE) – LiquidJS < 10.26.0

Be the first to know when new zero-days emerge:

Summary

CVE-2026-45618 is a critical code injection vulnerability (CWE-94) in LiquidJS, the widely used Node.js implementation of Shopify’s Liquid template language (7.3M+ monthly npm downloads). Versions prior to 10.26.0 allow an unauthenticated, remote attacker to submit a specially crafted Liquid template that escapes the sandboxed filter/tag evaluation logic and reaches Node.js’s Function constructor, resulting in arbitrary code execution on the host. The flaw carries the maximum CVSS v3.1 score of 10.0.

Technical details

  • Root cause: The Liquid class constructor initializes its filters and tags registries as plain JavaScript objects rather than null-prototype objects. This means template authors can reference properties inherited from Object.prototype (e.g. valueOf, constructor, toString) as if they were legitimate registered filters/tags.
  • Initial leak: A template expression such as 1|valueOf returns a reference to the rendering context (this), exposing internal engine objects such as the loader, filesystem handler, and parser.
  • Gadget chain: Attackers can overwrite __proto__ and manipulate comparison filters (equals, gt, geq, lt, leq) so that a subsequent comparison invokes an attacker-chosen function with this bound to the scope object, eventually reaching the Function constructor.
  • File-read/parse gadget: By further overwriting loader.lookup and readFile methods (and, per public PoC analysis, targeting Parser._parseFile), the attacker controls the content fed back into the parser, enabling arbitrary JavaScript execution — demonstrated in public proofs-of-concept via child_process.execSync.
  • Attack vector: Network-based, no authentication or user interaction required — any application feature that renders attacker-influenced or untrusted content as a Liquid template (CMS themes, email templating, static site generators, Shopify-style storefront customization, etc.) is exploitable.
  • Impact: Full compromise of confidentiality, integrity, and availability on the host process running the vulnerable template engine (scope change per the CVSS vector).

Affected software

  • liquidjs (npm package, maintained by harttle) — all versions prior to 10.26.0
  • Any application, CMS, email templating system, or Node.js service that embeds LiquidJS as a direct or transitive dependency and renders template input that is influenced by untrusted or external sources

Severity

  • CVSS v3.1 Base Score: 10.0 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade liquidjs to version 10.26.0 or later, which removes the ability to resolve Object.prototype properties as filters/tags and closes the associated gadget chains.
  • If immediate patching is not possible:
    • Do not render Liquid templates that contain any attacker-controlled, user-submitted, or otherwise untrusted content until the fix is applied.
    • Audit all application entry points (theme editors, email builders, CMS content fields, user-supplied templates) that pass external input into LiquidJS’s parseAndRender/render functions, and add strict input validation or disable that functionality temporarily.
    • Isolate template-rendering processes (e.g., via sandboxing, containers with restricted permissions, or separate low-privilege service accounts) to limit blast radius if exploitation occurs.
    • Monitor logs for anomalous Liquid syntax patterns such as valueOf, __proto__, or chained comparison filters in incoming template input.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
