AI Analysis
Technical Summary
CVE-2026-1630 is a reflected XSS vulnerability in WEBCON BPS affecting the "/openinmobileapp" endpoint. The vulnerability arises from improper neutralization of input during web page generation (CWE-79). An attacker can exploit this by sending a specially crafted URL that triggers execution of arbitrary JavaScript in the browser of an authenticated user. This can lead to potential session hijacking or other client-side attacks. The vulnerability is present in versions 2026.1.1.45 and 2025.1.1.87 and was addressed in versions 2026.1.3.109 and 2025.2.1.293.
Potential Impact
Successful exploitation allows execution of arbitrary JavaScript in the context of an authenticated user's browser session. This can lead to theft of session tokens, unauthorized actions performed on behalf of the user, or other client-side attacks. However, exploitation requires the victim to open a maliciously crafted URL and be authenticated to the affected WEBCON BPS instance.
Mitigation Recommendations
A fix is available and has been implemented in WEBCON BPS versions 2026.1.3.109 and 2025.2.1.293. Users should upgrade to these or later versions to remediate the vulnerability. No additional vendor advisory indicates other mitigation steps or that no action is required.
