CVE-2025-7825 is a medium-severity vulnerability affecting the Schema Plugin For Divi, Gutenberg & Shortcodes, a WordPress plugin developed by wpt00ls. The vulnerability arises from improper neutralization of directives in statically saved code, classified under CWE-96, which relates to static code injection. Specifically, the flaw is an object instantiation vulnerability via deserialization of untrusted input through the wpt_schema_breadcrumbs shortcode. This allows authenticated users with Contributor-level access or higher to inject a PHP object into the plugin's processing flow. However, the vulnerability alone does not lead to direct exploitation because no gadget or POP (Property Oriented Programming) chain is present within the plugin itself. A POP chain is necessary to leverage the deserialized object for malicious actions such as arbitrary code execution or file manipulation. If the target WordPress installation includes other plugins or themes that contain such POP chains, an attacker could chain this vulnerability with those to perform critical actions like deleting arbitrary files, retrieving sensitive data, or executing arbitrary code. The vulnerability has a CVSS 3.1 base score of 6.3, reflecting medium severity, with attack vector as network, low attack complexity, requiring privileges (Contributor or higher), no user interaction, and impacts on confidentiality, integrity, and availability. No known exploits are currently observed in the wild. The vulnerability affects all versions up to and including 4.3.2 of the plugin. No official patches or updates are currently linked, so mitigation relies on other controls or plugin updates when available.

For European organizations using WordPress sites with the vulnerable Schema Plugin For Divi, Gutenberg & Shortcodes, this vulnerability poses a moderate risk. The requirement for authenticated Contributor-level access limits exposure to insider threats or compromised accounts rather than anonymous attackers. However, many organizations allow multiple contributors or editors to manage content, increasing the attack surface. If the environment includes other plugins or themes that contain exploitable POP chains, the impact escalates significantly, potentially allowing attackers to execute arbitrary code, delete files, or exfiltrate sensitive data. This could lead to website defacement, data breaches, service disruption, or further lateral movement within the hosting infrastructure. Given the widespread use of WordPress in Europe for business, government, and e-commerce websites, exploitation could affect data confidentiality, integrity, and availability, damaging reputation and compliance posture under GDPR and other regulations. The lack of known exploits in the wild suggests limited active targeting currently, but the medium CVSS score and the possibility of chained exploitation warrant proactive attention.

1. Immediately review and restrict Contributor-level and higher privileges to trusted users only, minimizing the number of accounts that can exploit this vulnerability. 2. Monitor and audit user activity on WordPress sites to detect suspicious behavior indicative of exploitation attempts. 3. Temporarily disable or remove the wpt_schema_breadcrumbs shortcode usage if feasible until a patch is available. 4. Conduct an inventory of all installed plugins and themes to identify any that contain POP chains or are known to be vulnerable to deserialization attacks; consider disabling or updating them. 5. Apply the principle of least privilege on the hosting environment and file system permissions to limit the impact of any successful exploit. 6. Keep WordPress core, plugins, and themes updated regularly and watch for official patches from wpt00ls addressing this vulnerability. 7. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious deserialization payloads or unusual shortcode usage patterns. 8. Implement strong authentication mechanisms such as multi-factor authentication (MFA) for all users with elevated privileges to reduce the risk of account compromise. 9. Regularly backup website data and configurations to enable rapid recovery in case of compromise.
