Unauthenticated Access Control Bypass in FluentBooking Pro

Unauthenticated Broken Access Control in FluentBooking Pro < 2.5.0 versions.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-105072 represents a critical broken access control vulnerability affecting FluentBooking Pro versions prior to 2.5.0. This unauthenticated flaw allows attackers to bypass authorization mechanisms and gain unauthorized access to sensitive resources without requiring valid credentials. The vulnerability impacts organizations relying on FluentBooking Pro for booking management and reservation systems, potentially exposing customer data, booking records, and business logic to unauthorized actors. With a CVSS score of 7.5, this vulnerability poses a significant risk and warrants immediate patching across all affected deployments.

Casky's 283 mapped security skills leverage Claude AI with extended reasoning to detect attack patterns associated with this vulnerability across MITRE ATT&ACK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would identify telemetry indicators including: unauthenticated HTTP requests successfully returning sensitive data, absence of authorization tokens in requests accessing protected endpoints, unusual access patterns to administrative functions from unauthorized sources, and anomalous API calls bypassing authentication layers. The platform's skills would flag CWE-862 patterns—missing authorization checks—by correlating request characteristics, response codes, and data exposure events. Security teams would receive findings highlighting suspicious access attempts to FluentBooking Pro resources without proper authentication, enabling rapid detection and containment before exploitation reaches production systems.
