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
Unrestricted Upload of File with Dangerous Type vulnerability in Jordy Meow Photo Engine wplr-sync allows Upload a Web Shell to a Web Server.This issue affects Photo Engine: from n/a through <= 6.4.9.

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 confidence

Unrestricted file upload vulnerability in Jordy Meow Photo Engine wplr-sync allows unauthenticated or authenticated attackers to upload web shells to the web server, potentially enabling complete system compromise via remote code execution.

MitigationUpdate Photo Engine to a patched version. Until then, disable wplr-sync functionality, implement strict server-side file type validation (allowlist approach), and store all uploads outside the web root with executable permissions removed.

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. Identify Jordy Meow Photo Engine installation
    Search for the Photo Engine plugin or theme files in your WordPress installation (typically in wp-content/plugins/ or wp-content/themes/). Look for directories named 'photo-engine', 'meow-photo', or similar Jordy Meow products.
    Affected if The plugin or theme is found in the WordPress plugins or themes directory.
  2. Verify wplr-sync functionality is present
    Locate the wplr-sync component within the Photo Engine installation. Search for files, modules, or endpoints containing 'wplr-sync' in the codebase or exposed URLs.
    Affected if The wplr-sync functionality exists and is accessible within the installation.
  3. Check installed Photo Engine version
    If a version number is displayed in the WordPress admin plugin/theme page, or defined in the main plugin/theme file header, compare it against the patched version provided in the CVE reference.
    Affected if The installed version matches or falls within the affected version range.
  4. Inspect upload directory configuration
    Examine the web server configuration and the wplr-sync upload handling code to determine where uploaded files are stored. Check if the upload directory is within the web root (public_html, www, htdocs).
    Affected if Uploaded files are stored in a directory accessible via HTTP/HTTPS.
  5. Review file type validation
    Examine the wplr-sync upload handler to determine if server-side file type validation exists. Look for allowlist logic that restricts uploads to safe file types (images, documents) and rejects executable extensions (.php, .phtml, .exe, .js).
    Affected if No server-side file type validation exists, or the validation can be easily bypassed.

Your environment is affected if Jordy Meow Photo Engine with wplr-sync is installed, the wplr-sync component is accessible, and uploaded files can be stored in a web-accessible location without proper validation.
