CVE-2026-71445

Authenticated Reflected Cross-Site Scripting in Tag Error Responses in ail-framework

8.2 High

AIL Framework contained a reflected cross-site scripting vulnerability in the /tag/add_tags endpoint. When an error occurred while processing a tag operation, the application returned the error value directly as an HTML response using str(res[0]).

If attacker-controlled input was included in the generated error message, a crafted request could cause arbitrary HTML or JavaScript to be reflected in the response without appropriate output encoding. An attacker could exploit the vulnerability by convincing an authenticated AIL Framework user to open a specially crafted link.

Successful exploitation could allow JavaScript to execute in the victim’s browser within the security context of the AIL Framework application. Depending on the victim’s privileges and the application’s protections, the attacker could perform actions using the victim’s session, access information available to the victim, or modify data through authenticated application requests.

The vulnerability requires user interaction because the authenticated victim must follow or open the crafted request. The attacker does not necessarily require an AIL Framework account, provided that the crafted request can be delivered to an already authenticated user.
