Reflected XSS in Kiteworks Secure Data Forms

IdentifiersCVE-2026-24752CWE-79· Improper Neutralization of Input…

CVE-2026-24752 is a reflected cross-site scripting (XSS) vulnerability in Kiteworks Secure Data Forms affecting Kiteworks versions prior to 9.3.0. The flaw allows attacker-controlled input to be reflected back to a victim in a web response without proper neutralization, enabling arbitrary JavaScript execution in the victim's browser when the crafted request or link is opened. The issue is remotely reachable and does not require authentication, but exploitation requires user interaction. The advisory states that an external attacker can trick a user into executing arbitrary JavaScript code.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary JavaScript execution in the security context of the vulnerable Kiteworks application as rendered in the victim's browser. This can enable theft of session data or other sensitive browser-accessible information, unauthorized actions performed as the victim within the application, content manipulation, and other client-side impacts associated with reflected XSS. The provided CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) indicates high confidentiality impact, low integrity impact, no direct availability impact, and a changed scope.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, reduce exposure of Secure Data Forms to untrusted users where feasible and warn users not to open unsolicited or attacker-supplied Kiteworks links. Apply standard XSS hardening measures in front-end and application workflows where possible, such as strict output encoding and input handling, but the authoritative fix is to upgrade to Kiteworks 9.3.0 or later.

Remediation

Patch, then assume compromise.

Upgrade Kiteworks to version 9.3.0 or later. According to the advisory, version 9.3.0 contains the patch for this vulnerability.
