AnalysisAIv1 – Mar 28, 2026

Multiple plugins and/or themes for WordPress are vulnerable to unauthorized access due to a missing capability check on several AJAX actions like 'gsf_reset_section_options',. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Never evaluate user-controlled input as code. Use sandboxing, disable dangerous functions, apply strict input validation.

Technical ContextAI · show details

This vulnerability is classified as Code Injection (CWE-94), which allows attackers to inject and execute arbitrary code within the application. Multiple plugins and/or themes for WordPress are vulnerable to unauthorized access due to a missing capability check on several AJAX actions like 'gsf_reset_section_options', 'gsf_reset_section_options', 'gsf_create_preset_options' and more in various versions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to reset and modify some of the plugin/theme settings. This issue was escalated to Envato over two months from the date of this disclosure and the issues, while partially patched, are still vulnerable. Affected products include: G5Plus April, G5Plus Auteur, G5Plus Benaa, G5Plus Beyot.

Attack Technique

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
