Revive So CVE-2026-39561

While the CVSS 5.3 score suggests moderate risk with low confidentiality impact, the EPSS score of 0.02% (4th percentile) indicates this vulnerability has negligible real-world exploitation likelihood. The attack vector is network-based with no authentication or user interaction required, theoretically maximizing accessibility; however, the absence of public exploit code, lack of active exploitation confirmation, and extremely low EPSS percentile suggest the vulnerability is either difficult to exploit in practice, targets a narrow edge case, or affects a plugin with limited deployment. This represents a low-priority remediation despite moderate CVSS - a classic example of CVSS overestimation relative to true exploitation risk. Organizations should prioritize patching higher-EPSS vulnerabilities first.

An unauthenticated attacker sends a crafted network request to a WordPress site running Revive.so 2.0.7 or earlier, exploiting the misconfigured access control to read sensitive information protected by the plugin's access control layers. The attacker requires only network access and can carry out the attack without authentication or user interaction. No specialized exploit code has been publicly released, suggesting the attack likely requires knowledge of the specific misconfigured endpoints or parameter manipulation.
