CVE-2025-9985
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 · uneditedThe Featured Image from URL (FIFU) plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.2.7 through publicly exposed log files. This makes it possible for unauthenticated attackers to view potentially sensitive information contained in the exposed log files.
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 confidenceThe Featured Image from URL (FIFU) WordPress plugin stores log files that are publicly accessible via direct URL access, allowing unauthenticated attackers to retrieve potentially sensitive information from these exposed logs. This is a classic sensitive information exposure vulnerability stemming from improper access controls on log file storage.

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.
-
Verify FIFU plugin is installedCheck WordPress plugins directory or admin panel for 'Featured Image from URL' or 'FIFU' plugin presenceAffected if FIFU plugin is not installed on the WordPress site
-
Check installed FIFU versionInspect the plugin main file header or version constant in wp-content/plugins/fifu/includes/functions.php or via WordPress admin plugin listAffected if Version is below 5.2.8 (the fixed release)
-
Locate FIFU log filesSearch for log files in wp-content/plugins/fifu/ directory and subdirectories, looking for files with .log extension or named 'log', 'debug', or 'error'Affected if Log files exist in the plugin directory
-
Test public accessibility of log filesAttempt direct HTTP request to suspected log file URLs such as /wp-content/plugins/fifu/includes/log/ or direct paths to .log filesAffected if Log files return HTTP 200 and display contents without authentication
-
Check server access controls on log directoriesInspect .htaccess or nginx config files in plugin directories for RewriteRule or location blocks that block direct access to log foldersAffected if No access restrictions are configured for log directories
Environment is affected if FIFU plugin version is below 5.2.8 AND publicly accessible log files are present in the plugin directory structure.

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 dataUpdate the FIFU plugin to the latest version (5.2.8 or later) and audit the web root for any publicly accessible log files, securing or removing them immediately. Consider implementing web server rules to deny direct access to log directories.
