Deeper analysis
CVE-2023-36289 is an unauthenticated reflected cross-site scripting vulnerability (CWE-79) affecting Webkul QloApps version 1.6.0. The flaw resides in the handling of the email_create and back parameters in a POST request, allowing script injection that executes in the context of another user's session. It received a CVSS 3.1 score of 6.1 with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N.
An attacker with no authentication can craft a malicious POST request that triggers the XSS when a victim interacts with the link or form. Successful exploitation lets the attacker steal the victim's session cookie and impersonate the user within the QloApps application, achieving limited confidentiality and integrity impact with changed scope.
The single reference is a public Notion disclosure detailing the injection vector; no vendor advisory, patch information, or mitigation guidance is provided in the available data. The EPSS score has remained flat at 0.2372 with no documented rise after disclosure.
