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

This is a PHP Object Injection vulnerability caused by unsafe deserialization of untrusted data in the Pet World WordPress theme. Attackers can craft malicious serialized PHP objects and inject them into the application, potentially triggering magic methods to achieve remote code execution depending on available classes in the application ecosystem.

MitigationUpdate to the latest version of Pet World theme when available. If no patch exists, identify and remediate all unserialize() calls processing user-controlled input, implement allow-listing for permitted classes, or replace deserialization with JSON parsing.

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 if Pet World theme is installed
    Check for the presence of the /wp-content/themes/pet-world/ directory or search for 'Pet World' in the themes list via WordPress admin or wp_get_themes() function
    Affected if The Pet World theme directory exists in the WordPress installation
  2. Determine the installed theme version
    Open the theme's style.css file located at /wp-content/themes/pet-world/style.css and locate the 'Version:' header in the file comments, or check theme.json for the version field
    Affected if The version number is lower than the patched version (update to latest version recommended)
  3. Locate unserialize() calls in theme files
    Search all PHP files in the /wp-content/themes/pet-world/ directory for occurrences of 'unserialize(' using grep, grep -r "unserialize(" /wp-content/themes/pet-world/ or a file search tool
    Affected if Any unserialize() calls exist within the theme's PHP files
  4. Determine if unserialize() processes user-controlled input
    Review each found unserialize() call and trace whether its input source comes from $_GET, $_POST, $_COOKIE, $_REQUEST, or database fields that may contain user-submitted data
    Affected if unserialize() receives data from any HTTP request parameter, cookie, or untrusted database content
  5. Identify dangerous magic methods in the application
    Search PHP files in the theme and active plugins for class definitions containing __wakeup, __destruct, __toString, __call, or __invoke methods that could be chained for exploitation
    Affected if Classes with magic methods exist and the unserialize() vulnerability processes untrusted input

A user is affected if the Pet World theme is installed, contains any unserialize() calls that process user-supplied data, and has available classes with exploitable magic methods in the WordPress environment.
