CVE-2026-19598 in Pods Plugin
Summary
by MITRE • 08/15/2026
The Pods – Custom Content Types and Fields plugin for WordPress is vulnerable to Privilege Escalation via Authorization Bypass in all versions up to, and including, 3.3.9. The vulnerability exists because the pods_admin AJAX router funnels every access check — including the method allowlist, nonce verification, login enforcement, and capability gate — through pods_error(), which under the JSON meta-box-loader compatibility path only writes failures to the PHP error log and returns false instead of terminating the request, rendering all guards ineffective. This makes it possible for unauthenticated attackers to escalate their privileges to Administrator or overwrite the password of any user account, including the site owner's, enabling complete site takeover, or perform another administrator action.

The vulnerability in the Pods – Custom Content Types and Fields plugin for WordPress represents a critical privilege escalation flaw that undermines fundamental security controls. This issue affects all versions up to and including 3.3.9, making it particularly concerning given the widespread adoption of this popular WordPress plugin. The root cause lies in the improper handling of access control mechanisms within the pods_admin AJAX router implementation, where the security checks designed to protect administrative functions are systematically bypassed through a fundamental architectural flaw.
The technical flaw manifests specifically within the JSON meta-box-loader compatibility path where the pods_error() function serves as a critical point of failure. This function is responsible for validating various authorization components including method allowlists, nonce verification, login enforcement, and capability gates that should collectively prevent unauthorized access to administrative functions. However, under the problematic compatibility path, pods_error() fails to properly terminate requests when security violations occur, instead merely logging failures to the PHP error log and returning false values. This design decision effectively neutralizes all access control measures and creates a pathway for malicious actors to bypass authentication requirements entirely.
The operational impact of this vulnerability extends far beyond simple unauthorized access, creating conditions that enable complete site compromise. Unauthenticated attackers can leverage this flaw to escalate their privileges to administrator level access, effectively gaining the highest possible permissions within the WordPress environment. This privilege escalation capability allows attackers to overwrite passwords for any user account including the primary site owner, providing them with persistent access and control over all administrative functions. The implications are severe as this vulnerability enables full site takeover scenarios where attackers can modify content, install malicious plugins, alter user permissions, and potentially use the compromised site as a launchpad for further attacks against other systems.
The vulnerability aligns with CWE-284 (Improper Access Control) and represents a clear violation of the principle of least privilege that should govern all administrative interfaces. From an ATT&CK framework perspective, this issue maps directly to privilege escalation techniques and enables adversaries to move laterally within compromised environments while maintaining persistence. The bypass of nonce verification and capability checks creates an attack vector that could be exploited by automated tools, making it particularly dangerous in environments where WordPress plugins are frequently updated or deployed without proper security review processes. Organizations should immediately implement mitigations including plugin version updates, network segmentation, and enhanced monitoring for suspicious administrative activities.
The security implications extend to the broader WordPress ecosystem as this vulnerability demonstrates how seemingly minor implementation flaws can create cascading security issues. The failure to properly terminate requests during authentication failures creates a fundamental weakness that could potentially be exploited in combination with other vulnerabilities or attack vectors. This flaw also highlights the importance of proper error handling and the critical need for security controls to be implemented robustly rather than conditionally based on compatibility requirements. System administrators should conduct immediate vulnerability assessments across all WordPress installations using this plugin and consider implementing additional security layers such as web application firewalls and enhanced logging mechanisms to detect potential exploitation attempts.
