CVE-2024-9664·PHP vulnerability

The WP All Import Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.9.7 via deserialization of untrusted input from an import file. This makes it possible for authenticated attackers, with Administrator-level access and above, 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.

How to fix this CVE

Update WP All Import Pro to version 4.9.8 or later immediately. The vulnerability allows authenticated administrators to inject arbitrary PHP objects during import file processing, which could lead to code execution if a gadget chain exists in the WordPress environment. Ensure all plugins and themes are also kept current to minimize the risk of chained exploitation.

How to check if you are affected

  1. Step 1: Check installed WP All Import Pro version by running: grep -r "Version:" /path/to/wordpress/wp-content/plugins/wp-all-import-pro/wp-all-import-pro.php | head -1
  2. Step 2: Verify if the plugin is active by querying WordPress: wp plugin list | grep wp-all-import-pro (using WP-CLI on the server)
  3. Step 3: Search WordPress debug logs for deserialization errors: grep -i "unserialize\|object\|injection" /path/to/wordpress/wp-content/debug.log | grep -i "wp-all-import"
  4. Step 4: Confirm the patch by verifying the plugin version is 4.9.8 or higher: wp plugin get wp-all-import-pro --field=version

FAQ

What is CVE-2024-9664?

CVE-2024-9664 is a PHP Object Injection vulnerability in WP All Import Pro that occurs when the plugin deserializes untrusted data from import files without validation. An authenticated administrator could craft a malicious import file to inject arbitrary objects, potentially enabling code execution if gadget chains exist in other plugins or themes.

Is CVE-2024-9664 being actively exploited?

No, CVE-2024-9664 is not listed in the CISA KEV catalog and has no known public exploits available. However, the vulnerability requires administrator access, limiting its practical exploitation scope.

What versions of WP All Import Pro are affected by CVE-2024-9664?

All versions up to and including 4.9.7 are vulnerable. Version 4.9.8 and later contain the fix.

How do I check if my WordPress site is vulnerable to CVE-2024-9664?

Run: wp plugin get wp-all-import-pro --field=version to determine the installed version. If it returns 4.9.7 or earlier, your site is vulnerable.

Does Defensia detect CVE-2024-9664?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If WP All Import Pro is detected on a monitored WordPress installation, CVE-2024-9664 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-2025-25174CVSS 10Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in beeteam368 BeeTeam368 Extensions beeteam368-extensions allows PHP Local File Inclusion.This issue affects BeeTeam368 Extensions: from n/a through <= 1.9.4.
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.
