CVE-2025-5392: CWE-94 Improper Control of Generation of Code ('Code Injection') in gb-plugins GB Forms DB
The GB Forms DB plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.0.2 via the gbfdb_talk_to_front() function. This is due to the function accepting user input and then passing that through call_user_func(). This makes it possible for unauthenticated attackers to execute code on the server which can be leverage to inject backdoors or create new administrative user accounts to name a few things.
AI Analysis
Technical Summary
The GB Forms DB plugin for WordPress contains a remote code execution vulnerability (CVE-2025-5392) due to improper control of code generation (CWE-94). The vulnerable function gbfdb_talk_to_front() accepts user input and passes it directly to call_user_func(), enabling unauthenticated attackers to execute arbitrary code remotely. This can be exploited to inject backdoors or create administrative user accounts. The vulnerability affects all versions up to and including 1.0.2. The CVSS 3.1 base score is 9.8, reflecting critical severity with network attack vector and no required privileges or user interaction.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary code on the affected server. This can result in full system compromise, including the ability to install backdoors or create new administrative users, severely impacting confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor the vendor's communications for updates. Until a fix is available, consider disabling or removing the GB Forms DB plugin if possible to mitigate risk.
