CVE-2025-64266
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 · uneditedDeserialization of Untrusted Data vulnerability in magepeopleteam Booking and Rental Manager booking-and-rental-manager-for-woocommerce allows Object Injection.This issue affects Booking and Rental Manager: from n/a through <= 2.5.4.
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 confidenceThe plugin contains a deserialization vulnerability where untrusted data is passed to PHP's unserialize() function, allowing an attacker to potentially instantiate arbitrary PHP objects. This object injection could lead to code execution, SQL injection escalation, or file system attacks depending on available classes in the application.

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 if you have a PHP plugin using deserializationSearch your codebase for files containing 'unserialize(' calls. Use grep -r "unserialize(" /path/to/plugin/ or similar to locate the vulnerable function calls.Affected if The plugin contains any unserialize() calls that process data from user-controlled sources such as request parameters, POST/GET data, or database values.
-
Check if user input reaches unserialize()Review the code around each unserialize() call to trace whether data originates from $_GET, $_POST, $_REQUEST, database fields, or API inputs. Look for direct usage like unserialize($_POST['data']) or unserialize($row['field']).Affected if User-controllable input is passed directly to unserialize() without sanitization or validation.
-
Verify if input validation existsExamine whether the code performs any validation before the unserialize() call, such as checking for expected data types, using json_decode() instead, or implementing a whitelist of allowed classes.Affected if No validation, whitelisting, or safe deserialization method (like json_decode) is implemented before the unserialize() call.
-
Inspect available classes for dangerous magic methodsSearch the plugin for PHP magic methods like __destruct, __wakeup, __toString, or __invoke that could be chained with the object injection. Use grep -r "function __" within the plugin directory.Affected if The plugin contains classes with magic methods that could be exploited for code execution, file operations, or SQL injection escalation when deserialized.
You are affected if your plugin contains an unserialize() call that processes any untrusted or user-supplied data without prior validation or safe deserialization.

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.
From vendor dataReplace unsafe unserialize() calls with json_decode() or implement proper input validation with whitelisting if deserialization is absolutely required. Also ensure all available magic methods in the plugin do not provide dangerous attack vectors.
