CVE-2026-12587
The vulnerability allows the unauthorised generation of physical access QR codes due to the use of hard-coded credentials within the application.
Overview
CVE-2026-12587 is a known-severity vulnerability. It was published on August 26, 2026.
Technical description
The vulnerability allows the unauthorised generation of physical access QR codes due to the use of hard-coded credentials within the application. The generation mechanism uses the 'badge_number' parameter as the HMAC private key, the value of which remains static and is accessible via the API using the endpoint '/club/_id_club_/member/_id_member_/resamania_qr_info'. An attacker with access to this value and to the application’s cryptographic logic, which can be extracted by reverse engineering the APK as there is no code obfuscation, could generate valid QR codes indefinitely, even after the user has changed their password or logged out.

How can CyberStrike help with CVE-2026-12587?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-12587 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
