CVE-2024-43354
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 Saad Iqbal myCred mycred.This issue affects myCred: from n/a through <= 2.7.2.
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 confidenceA deserialization vulnerability in the myCred WordPress plugin (versions up to 2.7.2) allows unauthenticated attackers to deserialize untrusted data, likely through a PHP object injection attack. Given the CVSS 9.8 critical severity, this vulnerability is remotely exploitable and can lead to remote code execution.

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 myCred plugin installation and versionIn WordPress admin, go to Plugins > Installed Plugins and locate myCred, or check the plugin file /wp-content/plugins/mycred/readme.txt for the Version headerAffected if The installed version is 2.7.2 or lower (including any 2.x version below 2.7.2)
-
Identify deserialization entry pointsSearch plugin files for unserialize() calls: grep -r "unserialize" /wp-content/plugins/mycred/Affected if Any file contains unserialize() handling untrusted input without prior sanitization
-
Check for PHP object injection payloadsReview web server access logs for patterns like O: (PHP serialized object) or common gadget chain strings in query parametersAffected if Suspicious serialized data appears in HTTP requests to myCred endpoints
-
Detect post-exploitation indicatorsLook for newly created PHP files in /wp-content/ or /wp-content/uploads/ directories that were not intentionally uploadedAffected if Unexpected PHP files exist in these directories, suggesting successful RCE
-
Review user creation eventsCheck WordPress user tables (wp_users, wp_usermeta) for unauthorized administrator accounts created after the plugin was installedAffected if New administrator accounts exist that were not created by known administrators
You are affected if the myCred plugin version is 2.7.2 or lower, or if exploitation indicators are found in logs or file system.

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.
dbcve · scopedUpgrade myCred to the latest version immediately. If no patched version is available, disable the plugin until a fix is released.
myCred version 2.7.3 or later
- 1. Backup your WordPress database and files before making any changes.
- 2. Navigate to Plugins > Installed Plugins in your WordPress admin dashboard.
- 3. Find the myCred plugin in the list.
- 4. If an update is available, click 'Update Now' to upgrade to the latest version.
- 5. Alternatively, download the latest version from the official WordPress plugin repository or myCred website.
- 6. After updating, verify the plugin is functioning correctly and test critical user workflows.
