CVE-2024-25637
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 · uneditedOctober is a self-hosted CMS platform based on the Laravel PHP Framework. The X-October-Request-Handler Header does not sanitize the AJAX handler name and allows unescaped HTML to be reflected back. There is no impact since this vulnerability cannot be exploited through normal browser interactions. This unescaped value is only detectable when using a proxy interception tool. This issue has been patched in version 3.5.15.
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 confidenceThe X-October-Request-Handler header in October CMS reflects the AJAX handler name back to the client without HTML entity encoding. This creates unescaped HTML in the response that could theoretically be exploited for reflected XSS, but the vendor states it cannot be triggered through normal browser interactions and is only detectable via proxy interception tools. Patched in version 3.5.15.

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 October CMS installation versionLocate the version file or composer.json in the October CMS installation directory and read the installed version numberAffected if The installed version is 3.2.0 or higher but lower than 3.5.15
-
Verify the version falls within the affected rangeCompare your installed version against the range >= 3.2.0 and < 3.5.15Affected if Your version meets both conditions: it is 3.2.0 or newer AND is older than 3.5.15
-
Confirm AJAX handler header processing is in useInspect HTTP requests to identify if the X-October-Request-Handler header is being processed by the applicationAffected if The application processes the X-October-Request-Handler header and includes its value in responses without sanitization
You are affected if your October CMS version is 3.2.0 or higher but lower than 3.5.15 and the application processes the X-October-Request-Handler header.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped3.5.15
Upgrade to October CMS version 3.5.15 or later, which contains the patch that properly sanitizes the X-October-Request-Handler header value before reflection.
3.5.15 or later stable release
- 1. Backup your October CMS installation including the database and all files
- 2. Check your current October CMS version (typically in the backend or composer.json)
- 3. Update October CMS to version 3.5.15 or later using your preferred method: via composer run `composer update october/system` or through the backend update mechanism if available
- 4. Clear any application caches after upgrading (php artisan cache:clear)
- 5. Verify the installation by checking the version number and testing core functionality
