Vulnerability AssessmentAI
| Exploitation | Exploitation requires only that a vulnerable Kirki version (≤ 6.0.13) is installed and its affected endpoint is network-reachable - per the CVSS vector AV:N/AC:L/PR:N/UI:N, no authentication, no user interaction, and no special client configuration are needed against a default install. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are moderately consistent. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker enumerates a target WordPress site, identifies that a vulnerable Kirki version (≤6.0.13) is present via theme fingerprinting, and sends a crafted unauthenticated HTTP request to the affected Kirki endpoint. Because the authorization check is missing, the request is served and returns configuration or other sensitive data the attacker should not be able to read. … |
| Remediation | Upgrade Kirki to a release later than 6.0.13; the input confirms 6.0.13 and earlier are affected but does not state an exact fixed version, so released patched version is not independently confirmed - verify the fixed build via the Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/kirki/vulnerability/wordpress-kirki-plugin-6-0-13-broken-access-control-vulnerability?_s_id=cve) and the official plugin/theme changelog before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
