CVE-2026-9273: Software Security Vulnerability Vulnerability
CRITICALCVE-2026-9273 is a CRITICAL (CVSS 9.3) security vulnerability vulnerability (CWE-640: Weak Password Recovery Mechanism for Forgotten Password) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.. Remediation is available in the latest vendor maintenance releases.
CVE-2026-9273 at a Glance
Security Impact
CVSS: 9.3
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:R/S:C/C:H/I:H/A:N).
How to Fix CVE-2026-9273
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-2026-9273, 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 Membership Plugin – Kadence Memberships plugin for WordPress (formerly Restrict Content) is vulnerable to password reset link poisoning leading to account takeover in all versions up to, and including, 4.0.0. This is due to the legacy lost-password handler rc_process_lost_password_form() consuming the attacker-controlled rc_redirect POST parameter into two unvalidated sinks in legacy/includes/forms.php: wp_redirect( esc_url( $_POST['rc_redirect'] ) . ... ) at line 243, and add_query_arg( array( 'key' => $key, 'login' => ... ), $_POST['rc_redirect'] ) inside rc_send_password_reset_email() at line 306. The nonce required to reach the handler is broadcast by the public [login_form] shortcode at line 207 to any anonymous visitor. This makes it possible for unauthenticated attackers to issue a password-reset request for any account (including administrators) whose reset email body points the victim at an attacker-controlled host carrying a valid reset key/login. When the victim clicks the link, the reset key leaks to the attacker, who can replay it against the legitimate site to complete account takeover.",
