CVE-2026-6492: arnobt78 Hotel Booking Management System Health Check Endpoint detailed information disclosure
A vulnerability was detected in arnobt78 Hotel Booking Management System up to f8922d0e0f6ac1cc761974c7616f44c2bbc04bea. The impacted element is an unknown function of the file /api/health/detailed of the component Health Check Endpoint. Performing a manipulation results in information disclosure. Remote exploitation of the attack is possible. The exploit is now public and may be used. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The patch is named d47ae0e27c700b64dc417f7f01b84a6b1b0b6bd3. To fix this issue, it is recommended to deploy a patch.
Security readout for executives and security teams
Plain-English summary
CVE-2026-6492 is an information disclosure issue in arnobt78 Hotel Booking Management System. A detailed health-check API can expose internal information to remote, unauthenticated users. The issue is medium severity, but urgency increases because a public proof of concept is referenced. Organizations using this project should prioritize confirming exposure and applying the named patch.
Executive priority
Address in the next normal security remediation cycle, faster if the application is internet-facing or handles sensitive booking data. The business risk is leakage of internal system details that could support later attacks, not direct data modification or service outage based on current sources.
Technical view
The vulnerability affects the Health Check Endpoint file /api/health/detailed in arnobt78 Hotel Booking Management System up to commit f8922d0e0f6ac1cc761974c7616f44c2bbc04bea. It is classified as CWE-200 and CWE-284. CVSS 4.0 is 6.9 with network attack vector, low complexity, no privileges, and no user interaction. The named fix is commit d47ae0e27c700b64dc417f7f01b84a6b1b0b6bd3.
Likely exposure
Exposure is most likely where this MERN hotel booking application is deployed with the detailed health-check endpoint reachable from untrusted networks. Versioning is commit-based due to rolling release delivery, so teams must compare deployed code against the affected and patched commits.
Exploitation context
The source bundle states remote exploitation is possible and that exploit code is public. It is not listed in KEV, and the provided sources do not show confirmed active exploitation in the wild. Treat internet-exposed instances as higher priority because exploitation requires no authentication or user interaction.
Researcher notes
Evidence is primarily from VulDB/CVE records and linked GitHub references. Affected versioning is imprecise because the project uses rolling releases. The vulnerable function is not named beyond the /api/health/detailed endpoint. Avoid assuming broader product impact beyond the listed repository and commits.
Mitigation direction
Apply patch commit d47ae0e27c700b64dc417f7f01b84a6b1b0b6bd3 from the upstream repository.
Identify deployments based on commits at or before f8922d0e0f6ac1cc761974c7616f44c2bbc04bea.
Check vendor or project guidance for any additional remediation steps.
Limit public exposure of diagnostic health endpoints where operationally feasible.
Validation and detection
Inventory any arnobt78 Hotel Booking Management System deployments.
Confirm whether deployed code includes the patched commit.
Verify /api/health/detailed no longer exposes sensitive internal details.
Review access logs for unexpected requests to the detailed health endpoint.
