CVE-2026-48213: Open ISES Tickets < 3.44.2 Reflected XSS via add.php ticket_id Parameter

Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in add.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the ticket_id POST parameter directly into an HTML form input value attribute. Attackers can craft a malicious request containing a JavaScript payload that executes in the victim's browser when the response is rendered.

Security readout for executives and security teams

Plain-English summary

An authenticated user can manipulate a ticket request so malicious JavaScript runs when another user views the returned page. Successful abuse could expose browser-accessible data or perform actions as the victim. Exploitation requires user interaction and does not directly affect service availability.

Executive priority

Schedule prompt remediation, prioritizing internet-accessible and multi-user installations. The moderate rating reflects constrained exploitation requirements, but successful browser execution could compromise user sessions or trusted application actions.

Technical view

Open ISES Tickets versions before 3.44.2 reflect the add.php ticket_id POST value into an HTML input value attribute without adequate sanitization. This enables reflected cross-site scripting. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges, user interaction required, with limited confidentiality and integrity impact across a security boundary.

Likely exposure

Exposure exists where Open ISES Tickets before 3.44.2 is deployed and authenticated users can access add.php. Internet-accessible or broadly shared installations have greater practical risk. The supplied affected-version metadata is inconsistent, but the description and references identify versions before 3.44.2.

Exploitation context

The attacker must be authenticated and persuade a victim to render a crafted response. The source bundle provides no evidence of active exploitation, and the CVE is not identified as KEV. This does not prove exploitation is absent.

Researcher notes

This is CWE-79 reflected XSS caused by unsafe attribute-context output handling. The referenced patch commit and 3.44.2 release are the strongest remediation evidence supplied. Assess encoding specifically for HTML attribute context and verify regression coverage without using executable payloads.

Mitigation direction

  • Upgrade Open ISES Tickets to version 3.44.2 or later.
  • Review the vendor release and patch references before deployment.
  • Restrict application access to trusted users until upgrading.
  • Monitor authenticated activity involving unusual add.php requests.

Validation and detection

  • Inventory Open ISES Tickets instances and record their exact versions.
  • Confirm every deployed instance is version 3.44.2 or later.
  • Verify add.php requires authentication and intended authorization.
  • Test safely that ticket_id values are encoded within rendered HTML attributes.
  • Review relevant application and proxy logs for suspicious add.php activity.
