Missing Authorization vulnerability in Webba Plugins Webba Booking allows Exploiting Incorrectly Configured Access Control Security Levels.
This issue affects Webba Booking: from n/a through 6.4.13.
AnalysisAI
Unauthenticated remote attackers can bypass access controls in the Webba Booking WordPress plugin (all versions through 6.4.13) due to missing server-side authorization checks on one or more booking-related endpoints, enabling unauthorized integrity-affecting actions such as creating, modifying, or canceling bookings. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms zero-friction exploitation requiring no credentials or user interaction against any internet-facing WordPress site running the affected plugin. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target WordPress installation to have the Webba Booking plugin installed and active at version 6.4.13 or earlier. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.3 (Medium) reflects a genuinely limited impact profile: while the attack is fully unauthenticated and network-reachable with low complexity (AV:N/AC:L/PR:N/UI:N), the scope is unaffected (S:U) and impact is confined to partial integrity (I:L) with no confidentiality or availability consequence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with no account or prior access scans for WordPress sites running Webba Booking via passive reconnaissance (e.g., wappalyzer fingerprinting, plugin enumeration) and sends a crafted unauthenticated HTTP POST request to the vulnerable booking endpoint. The missing authorization check allows the request to proceed, enabling the attacker to manipulate booking records - for example, bulk-canceling appointments or injecting fraudulent reservations - without ever authenticating. … |
| Remediation | Upgrade Webba Booking to a version above 6.4.13 once a patched release is published by the vendor. … Detailed patch versions, workarounds, and compensating controls in full report. |
