Allegra - Authentication Bypass (CVE-2025-6216)

CVE-2025-6216 is an authentication bypass vulnerability, which allows remote attackers to exploit a weakness in the password recovery mechanism due to predictable password reset tokens. By leveraging this flaw, attackers can bypass authentication without valid credentials, potentially gaining unauthorized access to sensitive application resources.

CrowdSec has been tracking this vulnerability and its exploits since 16th of July 2025.

Data from the CrowdSec community indicates that exploitation of CVE-2025-6216 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations. Data from the CrowdSec community also indicates a gradual decrease in attacks targeting CVE-2025-6216. While still present in the wild, exploitation levels have dropped noticeably week-over-week. This may signal that the vulnerability is becoming less relevant or that defenses are improving fast enough for attackers to lose interest.

Attackers exploit predictable password reset tokens by targeting the /resetPassword.action and /resetPassword!confirm.action endpoints, allowing them to bypass authentication and gain unauthorized access.
