Vulnerability AssessmentAI

Exploitation No special conditions - remote unauthenticated exploitation against default configurations of the Salon Booking System WordPress plugin at version 10.30.25 or earlier, reachable over standard HTTP/HTTPS, with no user interaction and no authentication required (CVSS AV:N/AC:L/PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) describes a remote, unauthenticated, low-complexity flaw with high confidentiality impact but no integrity or availability impact, yielding a base score of 7.5 - consistent with sensitive data exposure rather than full takeover. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker scans the internet for WordPress sites running Salon Booking System 10.30.25 or earlier, then issues crafted unauthenticated HTTP requests directly to the plugin's vulnerable endpoint to retrieve sensitive booking, customer, or configuration data. Because no authentication, user interaction, or unusual configuration is required, the request can be automated at scale by commodity scanners, and harvested customer PII could feed downstream phishing or fraud campaigns.
