Vulnerability AssessmentAI

Exploitation	Attack requires site administrator privileges on a WordPress multisite installation (single-site WordPress does not expose the plugin settings to non-admin users in the same manner). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	CVSS 3.5 with network vector (AV:N) and high privilege requirement (PR:H) presents a moderate-severity profile with significant limiting factors. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	A malicious site administrator on a WordPress multisite installation accesses the plugin settings and modifies the Site Key field to inject JavaScript that sends login credentials to an attacker-controlled server. When visitors attempt to log in, the injected code loads invisibly and exfiltrates their username and password. …
Remediation	Update reCaptcha by WebDesignBy plugin to version 2.0 or later; vendor-released patch is available. … Detailed patch versions, workarounds, and compensating controls in full report.
