Security Impact
CVSS: 8.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-12407
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-2026-12407, 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 E2Pdf – Export Pdf Tool for WordPress plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.32.26. This is due to the screen_action() function lacking a dedicated capability check and nonce verification — when invoked via the ?action=screen routing path the controller's index_action() nonce gate is bypassed entirely — while reading an attacker-controlled option name and value from $_POST['wp_screen_options'] and passing them directly to update_option() with no allowlist, relying solely on the page-level e2pdf_templates capability which the plugin's own Permissions UI allows administrators to grant to any role including Subscriber, Contributor, Author, or Editor. This makes it possible for authenticated attackers, with a custom role that has been granted the e2pdf_templates capability, to overwrite arbitrary WordPress options such as default_role and thereby escalate their privileges to administrator.",
