Summary

CVE-2026-56060 is a high-severity Unauthenticated Sensitive Data Exposure vulnerability in the Print Invoice & Delivery Notes for WooCommerce WordPress plugin by Tyche Softwares, affecting all versions up to and including 7.1.1. The flaw enables unauthenticated remote attackers to access sensitive customer and order information with no credentials required, earning a CVSS v3.1 score of 7.5 (HIGH). A patched version (7.1.2) has been released and immediate upgrade is strongly recommended.

Technical details

  • Root cause: Improper protection of sensitive document endpoints, classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), allowing unauthenticated retrieval of invoice and delivery note data generated by the plugin.
  • Trigger conditions: No authentication, no user interaction, and no special privileges are required — any remote actor with HTTP/HTTPS access to an affected WordPress site can exploit this vulnerability.
  • Attack vector: Network-based; exploitable remotely over standard web requests to the vulnerable plugin’s endpoints.
  • Impact: High confidentiality impact — invoices and delivery notes managed by the plugin contain customer PII, including billing information, shipping addresses, and order details, all of which can be accessed by unauthorized parties.

Affected software

  • Print Invoice & Delivery Notes for WooCommerce (WordPress plugin by Tyche Softwares) — all versions up to and including 7.1.1

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 the plugin to version 7.1.2 or later. The patched release is available from the official WordPress plugin repository. At the time of publication, version 7.2.0 is available for download.
  • If immediate patching is not feasible: Consider temporarily deactivating the plugin or applying web server or WAF rules to restrict unauthenticated access to invoice and delivery note document endpoints until the update can be applied.

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.
