Open ISES Tickets can expose sensitive data when generating reports

CVE advisorySeverity: HIGH (CVSS 8.2)

CVE-2026-48246

Open ISES Tickets improperly disables security checks when making external requests, potentially exposing sensitive API keys or session data to attackers who can intercept network traffic.

2Halo Surface Signal

External exposure likelihood

Halo Surface Signal score for CVE-2026-48246

The vulnerability exists in server-side code that initiates outbound HTTPS requests to an external API service. This is a backend integration process rather than a public-facing service or interface, and exploitation requires an attacker to be positioned on the specific network path between the application server and the external API provider, which is uncommon for standard deployments.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability in Open ISES Tickets could allow an attacker to intercept sensitive data, such as API keys, sent to Google Maps. The issue arises because the software improperly handles security checks when making external requests.

  • Sensitive data can be exposed.
  • Requires specific network positioning to exploit.

Attack Path

How an attacker could exploit the issue

An attacker on the network path between the Open ISES Tickets server and Google Maps API can intercept HTTPS requests due to disabled TLS certificate verification. This allows them to view or alter traffic, potentially stealing API keys or session data.

  • Requires network man-in-the-middle.
  • Targets outbound API requests.
  • Exploits unverified TLS connections.

Live Threat

Current exploitation, exposure, and threat context

Attackers are unlikely to weaponize this CVE because it resides in server-side code handling outbound API calls, not a direct user-facing vulnerability. Exploitation demands a specific network position to intercept traffic, a scenario less common than directly attacking web interfaces.

  • No observed public exploit.
  • No KEV listing.
  • No recent exploitation signals.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Prioritize patching Open ISES Tickets to version 3.44.2 to re-enable TLS certificate verification and prevent man-in-the-middle attacks. If patching is delayed, implement network segmentation or strict firewall rules to restrict access to the Google Maps Directions API and monitor outbound traffic for unusual certificate validation errors or unexpected connections.

  • Patch to version 3.44.2.
  • Monitor network traffic for anomalies.
  • Restrict API access if patching is delayed.

Frequently asked questions

What is Open ISES Tickets and its function regarding external services?

Open ISES Tickets is a software application designed for managing incidents and generating reports. It is configured to make outbound HTTPS requests to external services, such as the Google Maps Directions API, which is utilized during the incident report generation process.

How does CVE-2026-48246 represent a security weakness?

CVE-2026-48246 is characterized by CWE-295, Improper Certificate Validation. This occurs because Open ISES Tickets disables TLS certificate verification when initiating external API calls, specifically by setting CURLOPT_SSL_VERIFYPEER to false without also setting CURLOPT_SSL_VERIFYHOST.

What is the trigger path for CVE-2026-48246 and what is out of scope?

The vulnerability is triggered within the ajax/reports.php file when Open ISES Tickets makes outbound HTTPS requests for Google Maps Directions API lookups during incident report generation. The scope is limited to an attacker on the network path between the server and the remote endpoint.

What is the relevance of CVE-2026-48246 according to threat advisory information?

According to threat advisory information, this CVE is classified as external due to its network attack vector, but its exploitation is considered unlikely. This is because it affects server-side code for outbound API calls, not a direct user-facing interface, and requires a specific network position for interception.

What actions should be taken to address CVE-2026-48246?

The recommended action is to update Open ISES Tickets to version 3.44.2 or later to restore TLS certificate verification. If immediate patching is not feasible, implement network segmentation and monitor outbound traffic for suspicious activities related to certificate validation or unexpected connections.
