Security Impact
CVSS: 9.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
How to Fix CVE-2026-81649
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-81649, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

"details" : "The Fundiin cho WooCommerce WordPress plugin through 3.4.0 does not have proper authorisation on several of its REST API routes, relying instead on a credential that is identical on every installation, allowing unauthenticated attackers to disclose the store's payment credentials and customer order data, overwrite the payment gateway configuration so that payments are credited elsewhere, and mark unpaid orders as paid. The same missing authorisation also allows arbitrary script to be stored in a field which is output unescaped on the classic checkout, leading to unauthenticated stored XSS on stores that do not use the block-based checkout.",
