CVE-2026-24987
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 activity-log.com WP System Log winterlock allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WP System Log: from n/a through <= 1.2.7.
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 WP System Log plugin (winterlock) allows attackers to exploit incorrectly configured access control security levels. The plugin fails to properly validate user permissions before allowing access to sensitive system log functionality, enabling unauthorized users to potentially view or manipulate logs beyond their intended access rights.

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 if WP System Log plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'WP System Log' by winterlock. Alternatively, check the wp-content/plugins directory for a folder named 'wp-system-log' or similar winterlock-related plugin folder.Affected if The plugin is installed and active on the WordPress site
-
Verify the plugin version against available patchesIn the WordPress plugin repository or the plugin settings panel, note the installed version number. Compare this to the latest version available from the WordPress plugin directory or the developer's site.Affected if The installed version lacks the security fix for missing authorization checks (any version without proper capability enforcement)
-
Inspect access control configurationReview the plugin files (typically in the main plugin PHP file) for presence of capability checks like 'current_user_can()' before sensitive functions that handle system logs. Look for functions that read, display, or manipulate log data.Affected if No capability checks exist before sensitive log functions, or checks are present but use weak/inadequate capabilities for the operation
-
Test unauthorized access from a low-privilege accountCreate or use a WordPress user with a low role (e.g., Subscriber). Attempt to access the WP System Log plugin features directly via its admin menu or any public-facing endpoints the plugin provides. Verify if the user can view or modify log data without proper authorization.Affected if A user without administrative privileges can access, view, or manipulate system logs through the plugin
A user is affected if the WP System Log plugin is installed and allows access to sensitive log functionality without proper WordPress capability checks, enabling unauthorized users to bypass role-based access controls.

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 dataImplement proper WordPress capability checks (using current_user_can()) and nonce verification on all sensitive functions within the plugin to enforce role-based access control. Update to the latest patched version when available.
