CVE-2026-48217: Open ISES Tickets < 3.44.2 Reflected XSS via delete_module.php Multiple POST Parameters
Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in delete_module.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the multiple POST parameters (module_choice, flag, confirmation) directly into rendered HTML content and form action attributes. 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 place malicious script content into requests to an Open ISES Tickets administration endpoint. If a victim renders the resulting response, the script runs in their browser, potentially exposing limited information or influencing actions under their session. Availability is not affected according to the CVSS assessment.
Executive priority
Schedule remediation promptly within the normal vulnerability-management cycle. Accelerate upgrading for internet-facing systems or deployments with less-trusted authenticated users. The medium severity reflects required authentication and victim interaction, while cross-session browser impact still creates confidentiality and integrity risk.
Technical view
Open ISES Tickets versions before 3.44.2 improperly render unsanitized module_choice, flag, and confirmation POST values in delete_module.php HTML content and form action attributes. This reflected cross-site scripting issue requires network access, low privileges, and victim interaction. Its CVSS 3.1 score is 5.4, with changed scope and low confidentiality and integrity impact.
Likely exposure
Exposure is limited to Open ISES Tickets installations before 3.44.2 where authenticated users can reach delete_module.php. Internet-accessible deployments and environments granting accounts to less-trusted users warrant faster review. The source bundle does not identify affected deployment counts or specific configurations.
Exploitation context
The attacker must be authenticated and persuade a victim to render a crafted response. No CISA KEV listing or other evidence of active exploitation is provided. The vulnerability is therefore a credible browser-based abuse risk, but observed exploitation cannot be claimed from the available evidence.
Researcher notes
CWE-79 applies. The affected sink spans rendered HTML content and form action attributes, with three named POST inputs. Validation should examine context-appropriate output encoding rather than only input filtering. The supplied patch and 3.44.2 release are the authoritative remediation references; the bundle provides no confirmed exploitation telemetry.
Mitigation direction
Upgrade Open ISES Tickets to version 3.44.2 or later.
Review the vendor release notes and patch commit before deployment.
Restrict application accounts to trusted users until upgrading.
Monitor access to delete_module.php for suspicious POST activity.
Validation and detection
Inventory Open ISES Tickets instances and record their installed versions.
Confirm every instance runs version 3.44.2 or later.
Verify the vendor patch is present in deployed source code.
Test authorized non-production responses to confirm submitted values are safely encoded.
Review authentication and access logs for unusual delete_module.php requests.
