Unauthenticated Local File Inclusion in Vavo Core <= 2.3.0 versions.

AnalysisAI

Remote Local File Inclusion in Vavo Core WordPress plugin versions 2.3.0 and earlier enables unauthenticated network-based attackers to include arbitrary local files from the server filesystem. Affecting WordPress installations running the spabrice-developed plugin, exploitation can expose highly sensitive files such as wp-config.php, leading to database credential theft and potential full site compromise. …

Vulnerability AssessmentAI

Exploitation The target must be a WordPress installation with the Vavo Core plugin actively installed and running at version 2.3.0 or earlier - this is a non-default WordPress configuration dependent on deliberate plugin installation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H yields a score of 8.1 and describes a remotely exploitable, unauthenticated flaw with no user interaction needed, but the High Attack Complexity rating is a meaningful limiter - it indicates some non-trivial precondition must be satisfied before exploitation succeeds, which reduces the likelihood of indiscriminate mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Administrators should update the Vavo Core plugin to a version above 2.3.0 immediately upon availability of a patched release from spabrice; the exact patched version number is not confirmed in the available intelligence, so the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/vavo-core/vulnerability/wordpress-vavo-core-plugin-2-3-0-local-file-inclusion-vulnerability and the official WordPress plugin repository should be consulted directly for the current safe release. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Audit all WordPress installations to identify those running Vavo Core plugin version 2.3.0 or earlier; immediately disable and remove the plugin from production environments to eliminate the attack surface for this unauthenticated local file inclusion vulnerability. …
