Speak to Experts

CVE-2025-10908 is a high-severity vulnerability due to a lack of user account state validation during authentication. This vulnerability allows locked user accounts to be successfully authenticated using Magic Link or Pass Key methods, effectively bypassing the intended security control that should prevent access to accounts that have been locked. This situation poses a significant risk as it may allow unauthorized access to applications and sensitive data associated with those accounts.

Risk to organizations includes undermining the effectiveness of the account lock mechanism intended to prevent further login attempts. Given the high CVSS score of 7.3, this vulnerability requires immediate attention from security teams to mitigate potential exploitation.

Currently, the vulnerability status is awaiting analysis, and there are no known exploits or proof of concept available. However, organizations should prioritize addressing this issue to safeguard against unauthorized access.

Organizations should prioritize patching immediately. The implications of this vulnerability could lead to significant data breaches if not addressed promptly.

Vulnerability Details

The official CVE description states that this vulnerability allows locked user accounts to be authenticated improperly, bypassing security controls. The vulnerability falls under the category of CWE-863, which pertains to authentication bypass issues.

The CVSS score of 7.3 signifies a high severity level, indicating that attackers may exploit this vulnerability with relatively low complexity and no privileges required. The attack vector is network-based, meaning that an attacker does not need physical access to the system.

This vulnerability was published on May 11, 2026, and it continues to pose a significant risk to affected systems until proper remediation is implemented.

Technical Analysis

The root cause of CVE-2025-10908 stems from insufficient validation of user account states during the authentication process. Specifically, the system fails to verify whether an account is locked before permitting access via Magic Link or Pass Key methods.

The attack vector is network-based, and the attack complexity is low. No privileges are required for an attacker to exploit this vulnerability, as user interaction is also not necessary. This means that the confidentiality, integrity, and availability impacts are all low, but the potential for unauthorized access remains a severe concern.

Risk & Impact Analysis

Real-world deployment risks associated with CVE-2025-10908 are significant. The vulnerability allows attackers to bypass account lock mechanisms, leading to unauthorized access to sensitive data. This could result in financial losses, reputational damage, and potential legal ramifications for organizations.

Organizations should assess their systems for exposure to this vulnerability and implement necessary remediation steps as soon as possible. Given its high CVSS score, this vulnerability should be treated with urgency.

Affected Versions

All versions prior to vendor patch are affected. Organizations should consult their vendor for the specific patches applicable to their systems.

Mitigation & Remediation

Organizations should prioritize patching immediately. Ensure that user account validation mechanisms are robust and that locked accounts cannot be authenticated through Magic Link or Pass Key methods. For systems without a patch, consider implementing additional access controls to mitigate the risk.

For continuous monitoring of security posture, organizations should engage in continuous penetration testing to identify and remediate similar vulnerabilities.

Detection Guidance

Monitor logs for indicators of unauthorized access attempts, especially concerning locked accounts. Look for behavioral anomalies, such as repeated authentication attempts using Magic Link or Pass Key methods, which could signify exploitation attempts.
