Summary

CVE-2025-13613 is a critical-severity Authentication Bypass by Alternate Name (CWE-289) vulnerability in Themeforest (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 39th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-4 (Identifier Management) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-13613 is an authentication bypass vulnerability affecting the Elated Membership plugin for WordPress in all versions up to and including 1.2. The issue stems from the plugin failing to properly log in a user after data verification through the 'eltdf_membership_check_facebook_user' and 'eltdf_membership_login_user_from_social_network' functions. It has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-289 (Authentication Bypass by Assumed-Immutable Data).

Unauthenticated attackers can exploit this vulnerability to log in as administrative users, provided they have an existing account on the site—which can be easily created via the default temporary user functionality—and access to the target administrative user's email. Successful exploitation grants full administrative privileges, enabling high-impact confidentiality, integrity, and availability violations, such as data exfiltration, site modification, or complete takeover.

Vulnerability Data

The Elated Membership plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.2. This is due to the plugin not properly logging in a user with the data that was previously verified through the…

'eltdf_membership_check_facebook_user' and the 'eltdf_membership_login_user_from_social_network' function. This makes it possible for unauthenticated attackers to log in as administrative users, as long as they have an existing account on the site which can easily be created by default through the temp user functionality, and access to the administrative user's email.

Mitigating Controls (NIST 800-53 r5) AI

Requiring unique identification and authentication of users forces the system to resolve all name variants to a single identity before access is granted.

Identifier management directly requires authorization and uniqueness checks that eliminate alternate-name aliases for the same actor or resource.

PR.AA-03 mostly match
prevents

Strong authentication mechanisms directly prevent name-based bypass when they enforce canonical name checks.

PR.AA-01 partial match
prevents

Proper identity management reduces alternate-name collisions but does not guarantee canonicalization inside the auth decision.

PR.AA-05 partial match
prevents

Authorization policy enforcement assumes correct identity; the weakness occurs before policy is applied.

prevents

Access-control policy can mandate canonical-name checks but does not prescribe the technical implementation.

prevents

Identity-management processes can require unique, canonical identifiers, reducing alternate-name bypass risk.

degrades

Proper management of authentication credentials can include rules against duplicate or alias identities.

prevents

Access-rights provisioning can enforce canonical-name validation when granting rights.

prevents

Information-access-restriction mechanisms can implement canonical-name checks to prevent bypass.

prevents

Secure-authentication controls can require canonical identifiers and reject alternate names.
