Security readout for executives and security teams
Plain-English summary
CVE-2026-25454 is a broken access control issue in the WordPress theme The League by MVPThemes, affecting versions up to 4.4.1. A logged-in user could trigger functionality they should not be authorized to use, with the documented impact focused on availability. This is a medium-severity issue, but it matters for sites allowing user registration or many low-privilege accounts.
Executive priority
Prioritize review for public WordPress sites that allow user logins. This is not currently supported as actively exploited, but the availability impact and low attack complexity justify timely inventory, vendor guidance review, and remediation planning.
Technical view
The issue is classified as CWE-862, Missing Authorization. The CVSS 3.1 score is 6.5 with AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H. Sources identify The League theme through version 4.4.1 as affected. The public bundle does not describe the vulnerable function, exploit method, or a confirmed fixed version.
Likely exposure
Exposure is limited to WordPress sites using MVPThemes The League theme version 4.4.1 or earlier. Risk is higher where untrusted users can log in, such as subscriber, contributor, membership, community, or ecommerce accounts.
Exploitation context
The CVSS vector indicates remote exploitation by an authenticated low-privilege user without user interaction. CISA KEV status is false in the provided data, and no cited source states active exploitation. Public technical details are limited in the provided sources.
Researcher notes
Evidence is sparse. The record identifies missing authorization in The League theme through 4.4.1, but does not provide endpoint-level detail, affected code paths, or a named patched version. Avoid assuming confidentiality or integrity impact because CVSS lists only high availability impact.
Mitigation direction
- Inventory WordPress sites for The League theme and version.
- Remove or disable the theme where it is not required.
- Check MVPThemes and Patchstack guidance for an update or workaround.
- Reduce unnecessary WordPress user accounts and privileges.
- Monitor application logs for unusual authenticated activity.
Validation and detection
- Confirm whether The League theme is installed on each WordPress site.
- Verify installed theme version is greater than 4.4.1 if a fixed release exists.
- Review user registration and low-privilege account exposure.
- Check vendor and Patchstack advisory pages for updated remediation details.
- Document compensating controls if no vendor fix is available.
