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 · unedited
Emlog is an open source website building system. Prior to version 2.6.11, missing CSRF protection in critical admin functions allows attackers to trick authenticated administrators into performing unauthorized actions like system registration, plugin management, and configuration changes. This issue has been patched in version 2.6.11.

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 · high confidence

Emlog before version 2.6.11 lacks CSRF (Cross-Site Request Forgery) protection in critical admin functions. Attackers can craft malicious pages that, when visited by authenticated administrators, silently trigger unauthorized actions including system registration, plugin management, and configuration changes via forged requests.

MitigationUpgrade to Emlog version 2.6.11 or later which includes CSRF protection. Additionally, implement anti-CSRF tokens (synchronizer token pattern) on all admin POST/PUT/DELETE endpoints and validate them server-side.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Emlog is installed
    Access the admin login page of the application (typically /admin/ or /admin/login.php) and verify the application is Emlog by checking the login page source or footer for 'Emlog' branding
    Affected if The application is Emlog and the admin interface is accessible
  2. Determine the installed Emlog version
    Locate the version identifier in the installation - common locations include a version.php file, the admin dashboard footer, or the system information page. Compare the version number to 2.6.11
    Affected if The installed version is below 2.6.11 (for example, 2.6.10, 2.6.9, etc.)
  3. Inspect admin forms for CSRF token fields
    Log into the Emlog admin panel and examine the HTML source of key admin forms (such as plugin management, system settings, or user registration forms). Look for hidden input fields containing token values or anti-CSRF parameters in POST requests
    Affected if The admin forms do not contain hidden CSRF token fields and rely solely on session authentication

The environment is affected if Emlog is running and the installed version is below 2.6.11, or if admin forms lack CSRF protection tokens regardless of version.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to Emlog version 2.6.11 or later which includes CSRF protection. Additionally, implement anti-CSRF tokens (synchronizer token pattern) on all admin POST/PUT/DELETE endpoints and validate them server-side.

Recommended fix High confidence

2.6.11

  1. 1. Back up the current Emlog installation and database before any upgrade.
  2. 2. Download Emlog version 2.6.11 from the official Emlog repository or distribution source.
  3. 3. Replace existing Emlog files with the new version 2.6.11 files, preserving any custom configurations if required.
  4. 4. Run any database migration scripts if included in the upgrade package.
  5. 5. Verify the upgrade by logging into the admin panel and confirming all functions work correctly.
