CVE-2026-35007: Open ISES Tickets < 3.44.2 Reflected XSS via single_unit.php id Parameter
Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in single_unit.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the id GET parameter directly into an HTML attribute. Attackers can craft a malicious URL containing a JavaScript payload in the id parameter that executes in the victim's browser when the URL is visited.
Security readout for executives and security teams
Plain-English summary
Open ISES Tickets versions before 3.44.2 can execute attacker-supplied JavaScript when a user follows a crafted ticket URL. Exploitation requires user interaction and could affect information or actions available within the victim’s browser session. The supplied evidence does not establish active exploitation.
Executive priority
Schedule remediation through the normal vulnerability-management cycle, prioritizing internet-accessible or broadly used deployments. Escalate if monitoring identifies suspicious crafted links or if privileged users regularly access the application. Current evidence does not justify emergency incident status by itself.
Technical view
CVE-2026-35007 is reflected cross-site scripting in single_unit.php. The id GET parameter is inserted into an HTML attribute without adequate sanitization or encoding. A crafted URL can therefore execute JavaScript when visited. The CVSS 4.0 score is 5.1, with low subsequent confidentiality and integrity impact.
Likely exposure
Exposure is limited to Open ISES Tickets deployments earlier than 3.44.2 where users can reach single_unit.php and be induced to open crafted links. The supplied affected-version metadata is imprecise, so organizations should verify actual installed versions directly.
Exploitation context
The CVE is not listed as KEV in the supplied bundle, and no source provided confirms exploitation in the wild. User interaction is required. The description calls attackers authenticated, while the CVSS vector specifies no privileges required; this prerequisite remains unclear.
Researcher notes
The remediation boundary and patch are supported by the 3.44.2 release and linked commit. Authentication requirements conflict between the narrative and CVSS vector, while the affected metadata lists only version “0” despite describing all releases before 3.44.2. Treat those fields cautiously during exposure analysis.
Mitigation direction
Upgrade Open ISES Tickets to version 3.44.2 or later, following vendor release guidance.
If upgrading is delayed, restrict application access and consult vendor guidance for supported temporary mitigations.
Advise users not to open untrusted single_unit.php links until remediation is verified.
Validation and detection
Inventory Open ISES Tickets deployments and record their installed versions.
Confirm no deployment runs a version earlier than 3.44.2.
Review application and proxy logs for unusual single_unit.php requests containing suspicious id values.
In authorized testing, verify id values are encoded and cannot alter the surrounding HTML attribute.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
