CVE-2025-46473
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 Prisna Social Counter social-counter allows Object Injection.This issue affects Social Counter: from n/a through <= 2.0.5.
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 confidencePHP Object Injection vulnerability in Prisna Social Counter plugin allows deserialization of untrusted data. Attackers can craft malicious serialized PHP objects to achieve remote code execution if magic methods exist in the application or other installed components.

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.
-
Check if Prisna Social Counter plugin is installedIn WordPress admin, go to Plugins > Installed Plugins, or inspect /wp-content/plugins/ directory for prisna-social-counter folderAffected if Plugin folder exists in the WordPress plugins directory
-
Determine installed plugin versionIn WordPress admin Plugins list, find Prisna Social Counter and note the version displayed. Compare this version against the vendor's release notes for the patched versionAffected if Installed version is older than the latest patched version released by vendor
-
Locate vulnerable deserialization codeUsing a code search tool or grep, search the plugin directory for 'unserialize(' function calls. Examine each occurrence to identify if it processes $_GET, $_POST, $_COOKIE, or other user-supplied inputAffected if unserialize() function is called on data derived from user input without validation
-
Identify input vectors reaching deserializationReview AJAX endpoints (admin-ajax.php calls), shortcode handlers, and public-facing plugin files. Check if serialized data can be submitted via URL parameters, form fields, or cookiesAffected if User-controllable data can reach the vulnerable unserialize() call without sanitization
You are affected if the Prisna Social Counter plugin is installed, contains unserialize() handling user input, and the installed version predates the vendor patch.

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 Social Counter plugin to latest version. If no patch available, remove the plugin or implement web application firewall rules to block serialized data in user-supplied inputs.
