Impact

The CVSS 5.3 score with AV:N/AC:L/PR:N indicates a network-accessible vulnerability requiring no privileges or user interaction, which is concerning. However, the integrity-only impact (I:L) with no confidentiality or availability damage tempers the severity. The missing Authorization class (CWE-862) combined with network accessibility and low complexity suggests moderate real-world exploitability. Without confirmed EPSS data or active KEV listing provided, the vulnerability should be treated as actionable but not critical—it requires an attacker to discover and exploit the misconfigured access control, and impact is limited to configuration tampering rather than data exfiltration or service disruption. Organizations running vulnerable versions should prioritize patching within a standard maintenance window rather than treating this as emergency. The plugin's popularity in WordPress environments increases attack surface exposure.

Exploit ScenarioDerived

An attacker identifies a target WordPress site running Really Simple SSL version 9.5.7 or earlier via plugin fingerprinting. The attacker crafts a malicious HTTP request to a misconfigured plugin endpoint that lacks proper authorization checks (network-accessible, no authentication required per CVSS vector). The attacker modifies security settings such as disabling HTTPS enforcement, redirecting traffic to an attacker-controlled domain, or changing redirect rules—all without authentication. Once modified, legitimate users' traffic may be intercepted or downgraded, enabling credential theft or man-in-the-middle attacks at the SSL/TLS layer.

AnalysisAIv1 – Mar 13, 2026

Really Simple SSL versions 9.5.7 and earlier contain an authorization bypass flaw that allows unauthenticated remote attackers to modify security settings through improper access control mechanisms. The vulnerability has a medium severity rating with a CVSS score of 5.3 and currently lacks a publicly available patch. Organizations using affected versions should review their SSL security configurations and consider upgrading when patches become available.

Earlier versions of this analysis (1)
v1 Mar 13, 2026 - 16:57 CVSS 5.3

A missing authorization vulnerability exists in Really Simple SSL versions through 9.5.7, allowing unauthenticated attackers to modify security configurations due to incorrectly configured access control levels. This CWE-862 vulnerability enables attackers to bypass authentication requirements and tamper with SSL/TLS settings on affected WordPress installations, potentially downgrading security posture or exposing sensitive configuration data. The CVSS 5.3 score reflects moderate integrity impact with no authentication required and network-level attack vector.

RemediationAI

Immediately upgrade Really Simple SSL to version 9.5.8 or later, which patches the missing authorization controls. Access the WordPress plugin dashboard, locate Really Simple SSL, and select the update option, or download the patched version directly from the Really Simple Plugins repository. Until patching is completed, mitigate exposure by restricting WordPress admin panel access via IP allowlisting, implementing a Web Application Firewall (WAF) rule to block unauthorized access to plugin configuration endpoints, and ensuring strong admin credentials are in place. For critical environments, consider temporarily disabling the plugin and managing SSL configuration through alternative methods (reverse proxy, hosting provider tools) until patching is verified in a staging environment.

Technical ContextAI · show details

Really Simple SSL is a WordPress security plugin (CPE identifier typically cpe:2.3:a:really_simple_plugins:really_simple_ssl) that manages SSL certificate configuration, HTTP-to-HTTPS redirection, and mixed content handling. The vulnerability stems from CWE-862 (Missing Authorization), which occurs when the plugin fails to properly enforce access control checks on administrative functions that modify security-related settings. The root cause involves insufficient privilege validation in REST API endpoints or admin interface functions that allow unauthenticated or low-privileged users to invoke security configuration changes. This is particularly critical because the plugin's core function is managing cryptographic and transport-layer security, making authorization flaws directly impact the application's defensive posture.
