CVE-2024-10962·PHP vulnerability

The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.9.107 via deserialization of untrusted input in the 'replace_row_data' and 'replace_serialize_data' functions. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code. An administrator must create a staging site to trigger the exploit.

How to fix this CVE

Update the WPvivid Backup & Restore plugin to version 0.9.108 or later to patch the PHP object injection vulnerability in the database serialization functions. This vulnerability allows unauthenticated attackers to inject malicious PHP objects during staging site creation, which could lead to arbitrary file deletion, data theft, or code execution if complementary gadget chains exist in other plugins. Immediately apply this update to all WordPress installations using WPvivid.

How to check if you are affected

  1. Check PHP version: php -v
  2. Verify WPvivid plugin version in WordPress: wp plugin list | grep wpvivid (if WP-CLI available), or manually inspect /wp-content/plugins/wpvivid-backuprestore/wpvivid.php for the Version header
  3. Search WordPress debug logs for deserialization errors: grep -r 'unserialize\|Object injection' /path/to/wordpress/wp-content/debug.log
  4. Confirm the patch: grep 'Version' /wp-content/plugins/wpvivid-backuprestore/wpvivid.php and verify version is >= 0.9.108

What is CVE-2024-10962?

CVE-2024-10962 is a PHP object injection vulnerability in the WPvivid Backup & Restore WordPress plugin that exists in the database serialization functions used during staging site operations. An unauthenticated attacker can inject a malicious serialized PHP object that gets deserialized without validation, potentially enabling remote code execution if suitable gadget chains are available in the WordPress environment.

Is CVE-2024-10962 being actively exploited?

No, this vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog and no public proof-of-concept exploits are publicly available. However, the high CVSS score (8.8) and ease of exploitation warrant immediate patching.

What versions of WPvivid are affected by CVE-2024-10962?

All versions of the WPvivid Backup & Restore plugin up to and including version 0.9.107 are vulnerable. Version 0.9.108 and later contain the fix.

How do I check if my server is vulnerable to CVE-2024-10962?

Use wp plugin list --field=name --status=active | grep wpvivid to identify if WPvivid is installed, then check the version in Settings or by inspecting the plugin's header comment. If the version is 0.9.107 or earlier, your installation is vulnerable.

Does Defensia detect CVE-2024-10962?

Yes — Defensia's CVE advisory scanner compares installed WordPress plugin versions against the NVD database. If WPvivid is installed on a monitored server, CVE-2024-10962 will appear in your dashboard with remediation steps.

CVE-2026-28289CVSS 10FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. A patch bypass vulnerability for CVE-2026-27636 in FreeScout 1.8.206 and earlier allows any authenticated user with file upload permissions to achieve Remote Code Execution (RCE) on the server by uploading a malicious .htaccess file using a zero-width space character prefix to bypass the security check. The vulnerability exists in the sanitizeUploadedFileName() function in app/Http/Helper.php. The function contains a Time-of-Check to Time-of-Use (TOCTOU) flaw where the dot-prefix check occurs before sanitization removes invisible characters. This vulnerability is fixed in 1.8.207.
CVE-2025-46348CVSS 10YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.
CVE-2025-47916CVSS 10Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.

CVE-2025-62521CVSS 10ChurchCRM is an open-source church management system. Prior to version 5.21.0, a pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The vulnerability exists in `setup/routes/setup.php` where user input from the setup form is directly concatenated into a PHP configuration template without any validation or sanitization. Any parameter in the setup form can be used to inject PHP code that gets written to `Include/Config.php`, which is then executed on every page load. This is more severe than typical authenticated RCE vulnerabilities because it requires no credentials and affects the installation process that administrators must complete. Version 5.21.0 patches the issue.
