Summary

CVE-2026-66465 is a critical unauthenticated authentication bypass vulnerability affecting the Cartify WooCommerce WordPress theme by AgniHD, versions up to and including 1.3.0.1. The flaw allows an attacker to bypass authentication controls through an alternate path or channel, resulting in account takeover without requiring credentials or user interaction. It carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: broken authentication logic classified as CWE-288 (Authentication Bypass Using an Alternate Path or Channel), allowing an unauthenticated attacker to access or take over accounts through a path that does not enforce the theme’s normal authentication checks.
  • Trigger conditions: no authentication or user interaction is required to exploit the flaw.
  • Attack vector: network-based, exploitable remotely over HTTP(S) against any WordPress site running the vulnerable theme.
  • Impact: full compromise of confidentiality, integrity, and availability, consistent with unauthorized account takeover (including potentially administrator accounts).

Affected software

  • AgniHD Cartify WordPress theme, version 1.3.0.1 and all earlier versions.

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade the Cartify theme to the latest version available from the vendor/marketplace beyond 1.3.0.1, as soon as a fixed release is published.
  • If no patch is confirmed available: Restrict or disable public access to the theme’s authentication-related functionality, monitor for anomalous account access or privilege changes, enforce multi-factor authentication on administrative accounts, and consider temporarily deactivating the theme or placing the site behind a web application firewall until a vendor fix is confirmed.

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.
