CVE-2026-27984 describes a Remote Code Execution (RCE) vulnerability within the Widget Options plugin for WordPress. This flaw allows attackers to inject arbitrary code, leading to complete server compromise. The vulnerability affects versions from 0.0.0 through 4.1.3, and a fix is available in version 4.2.0.
The 'Code Injection' vulnerability in Widget Options allows an attacker to execute arbitrary code on the server hosting the WordPress site. This is a severe risk, as it could lead to complete system takeover, data theft, defacement, or the installation of malware. An attacker could leverage this vulnerability to gain persistent access to the server, move laterally to other systems on the network, and exfiltrate sensitive data. The potential blast radius is significant, impacting any data stored on or accessible from the compromised server.
CVE-2026-27984 was publicly disclosed on 2026-03-05. The vulnerability is considered high probability due to the ease of code injection and the potential for significant impact. Public proof-of-concept exploits are likely to emerge, increasing the risk of widespread exploitation. This vulnerability is not currently listed on CISA KEV, but its severity warrants close monitoring.
WordPress websites utilizing the Widget Options plugin, particularly those running older versions (0.0.0–4.1.3), are at significant risk. Shared hosting environments are especially vulnerable, as they often have limited control over plugin updates and security configurations. Sites relying on legacy WordPress installations or those with inadequate security practices are also at increased risk.

The primary mitigation is to immediately upgrade the Widget Options plugin to version 4.2.0 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider temporarily disabling the plugin. As a short-term workaround, implement strict input validation and sanitization on any user-supplied data used by the plugin. Web Application Firewalls (WAFs) with code injection protection rules can also help mitigate the risk, although they are not a substitute for patching. Monitor WordPress logs for suspicious activity, particularly code execution attempts.
Update to version 4.2.0, or a newer patched version
