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
The Unseen Blog theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.0.0 via deserialization of untrusted input. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

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

The Unseen Blog theme for WordPress (versions up to 1.0.0) contains a PHP Object Injection vulnerability caused by unsafe deserialization of untrusted input. Authenticated attackers with Contributor-level access or higher can inject arbitrary PHP objects via the vulnerable deserialization mechanism. While the theme itself lacks a POP chain, if other plugins or themes on the same WordPress installation provide one, attackers could achieve arbitrary file deletion, data exfiltration, or remote code execution.

MitigationReplace any unsafe unserialize() calls in the theme with json_decode() or similar safe deserialization methods. If no patched version exists, consider removing the theme until a fix is available.

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 Unseen Blog theme is installed
    Navigate to Appearance > Themes in WordPress admin and check if the Unseen Blog theme appears in the installed themes list
    Affected if The Unseen Blog theme is listed as an active or installed theme
  2. Identify the theme version
    Access the theme files via FTP or file manager, then open style.css in the theme directory (wp-content/themes/unseen-blog/) and locate the 'Version:' header in the file comments
    Affected if The version listed is 1.0.0 or lower (the CVE specifies <=1.0.0 as affected)
  3. Locate deserialization code
    Search theme PHP files for unserialize() function calls, particularly any that process input from $_GET, $_POST, $_REQUEST, or user-supplied data without sanitization
    Affected if The theme contains unserialize() calls that process untrusted input without validation
  4. Verify contributor-level or higher users exist
    In WordPress admin, go to Users > All Users and review the role assigned to each user. Check for users with Contributor, Author, Editor, or Administrator roles
    Affected if Any user account with Contributor-level access or higher exists on the site
  5. Audit installed plugins for POP chain potential
    Review the list of active plugins in Plugins > Installed Plugins. Note that the theme vulnerability requires a separate plugin or theme to provide a POP chain for exploitation
    Affected if Multiple plugins are installed, particularly any that expose vulnerable magic methods (like __destruct, __wakeup, __invoke, __toString) that could form a POP chain

A user is affected if the Unseen Blog theme version is 1.0.0 or lower AND the theme contains unserialize() calls handling untrusted input AND at least one user with Contributor-level or higher access exists on the site, combined with a plugin/theme that provides a usable POP chain.

Upgrade available Upgrade to a release after 1.0.0
Interim mitigation

Replace any unsafe unserialize() calls in the theme with json_decode() or similar safe deserialization methods. If no patched version exists, consider removing the theme until a fix is available.

Recommended fix Low confidence

Latest version available on wordpress.org (version > 1.0.0)
