CVE-2026-25454
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMissing Authorization vulnerability in MVPThemes The League the-league allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects The League: from n/a through <= 4.4.1.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMissing authorization vulnerability in the League theme allows attackers to bypass access control security levels due to incorrectly configured permissions, potentially enabling unauthorized access to privileged functionality or sensitive data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify League theme installationLocate the League theme files in your CMS or web application. Common locations include /themes/league, /wp-content/themes/league (WordPress), or similar theme directories.Affected if The League theme is present in the environment
-
Check theme versionExamine the theme's style.css, package.json, or version file to determine the installed version number.Affected if The installed version does not have the authorization patch applied (compare against vendor release notes when available)
-
Review permission configuration filesInspect the theme's permission, capability, or access control configuration files (commonly in config/, inc/, or the main theme PHP files). Look for files defining user roles, capabilities, or access levels.Affected if Permission settings are missing, misconfigured, or allow role bypass on sensitive endpoints
-
Audit access control on sensitive functionsExamine the theme code for functions handling privileged actions (admin functions, user data access, content management). Verify that each includes proper authorization checks (current_user_can, verify_nonce, capability checks).Affected if Sensitive functions lack authorization verification or rely solely on superficial checks
-
Test for authorization bypassUsing a low-privilege or unauthenticated account, attempt to access functions or endpoints that should require elevated privileges (admin dashboard, user management, sensitive data views).Affected if Access is granted without proper authorization credentials
The environment is affected if the League theme is in use and authorization checks are missing or improperly configured on sensitive endpoints and functions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch when available; otherwise audit and enforce proper authorization checks on all sensitive endpoints and functions within the theme.
