CVE-2025-54742
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 WpEvently mage-eventpress allows Object Injection.This issue affects WpEvently: from n/a through <= 4.4.8.
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 confidenceThis is a PHP Object Injection vulnerability in the WpEvently WordPress plugin by magepeopleteam. The plugin deserializes untrusted data without proper validation, allowing authenticated attackers (or potentially unauthenticated depending on the code path) to instantiate arbitrary PHP objects. This can lead to remote code execution if available magic methods (__wakeup, __destruct, __toString) can be chained with POP gadgets present in the plugin or other WordPress plugins.

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.
-
Verify WpEvently plugin is installedNavigate to WordPress admin dashboard > Plugins > Installed Plugins. Look for 'WpEvently' by 'magepeopleteam' in the list. Note whether it is active or inactive.Affected if The plugin is installed and active, making the vulnerable code available to attackers.
-
Identify WpEvently plugin versionIn the Plugins list, click on 'WpEvently' to view plugin details, or check the plugin main PHP file header for 'Version:' comment. Compare this version to the latest patched version when published.Affected if Running any version prior to the patched release is potentially vulnerable.
-
Locate deserialization code in plugin filesAccess the site via file manager or FTP. In the wp-content/plugins/wp-evently/ directory, search PHP files for 'unserialize(' function calls. Common paths include ajax handlers, shortcodes, or widget files.Affected if The plugin contains unserialize() calls processing user-supplied data without validation.
-
Identify accessible entry pointsReview plugin PHP files for AJAX actions (wp_ajax_*), REST API endpoints, or shortcode handlers that accept serialized data. Check if these require authentication or are accessible to unauthenticated users.Affected if Deserialization occurs on an unauthenticated or low-privilege accessible endpoint.
-
Assess POP gadget availabilityReview all active WordPress plugins for potential PHP object injection gadgets (classes with __wakeup, __destruct, or __toString methods that could be chained for RCE).Affected if POP gadgets exist in the plugin or other active plugins, enabling remote code execution.
The environment is affected if the WpEvently plugin is active, contains unserialize() calls processing input, and the attack surface (AJAX/REST/shortcode) is accessible to attackers, combined with available POP gadgets for exploitation.

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 dataUpdate WpEvently plugin to the latest version when available. If no patch exists, disable the plugin and remove it from the WordPress installation. As a temporary measure, deploy a WAF rule to block deserialization-related payloads.
