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

Summary

CVE-2026-49061 is a high-severity Unauthenticated Arbitrary File Download vulnerability in WPC Product Options for WooCommerce (by WPClever), affecting all versions up to and including 3.2.1. The flaw stems from a path traversal weakness (CWE-22) that allows any unauthenticated remote attacker to retrieve arbitrary files from the server with no credentials or user interaction required. With a CVSS v3.1 base score of 7.5 (HIGH), exploitation can expose critical server-side files — including WordPress configuration files containing database credentials — potentially enabling full site compromise.

Technical details

  • Root cause: Improper limitation of a pathname to a restricted directory (path traversal / CWE-22), allowing file retrieval from outside the intended directory boundaries.
  • Trigger conditions: No authentication, privileges, or user interaction required — the flaw is exploitable by any remote, unauthenticated party.
  • Attack vector: Network-accessible (AV:N/AC:L/PR:N/UI:N); any internet-facing WooCommerce store running the vulnerable plugin version is exposed.
  • Impact: High confidentiality impact. An attacker can download arbitrary server-side files, including wp-config.php (containing database credentials, authentication keys, and salts), backup archives, and other sensitive data. Integrity and availability are not directly impacted.

Affected software

  • WPC Product Options for WooCommerce (WPClever) — versions <= 3.2.1

Severity

  • CVSS v3.1 Base Score: 7.5 (HIGH)
  • Vector string: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate: Update WPC Product Options for WooCommerce to version 3.2.2 or later, which contains the vendor-provided fix as confirmed in the official plugin changelog.
  • If immediate patching is not possible, consider temporarily deactivating the plugin and applying network-level controls (e.g., WAF rules) to restrict access to the WordPress installation until an upgrade can be performed.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

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.
