CVE-2026-0519 identifies a vulnerability in the Absolute Security Secure Access product, specifically in versions 12.70 and earlier than 14.20. The issue lies in the logging subsystem, which under certain configurations, records authentication tokens in an unredacted form within log files. These tokens are sensitive credentials used to authenticate users or systems to integrated services. The vulnerability is classified under CWE-532, which concerns exposure of sensitive information in logs. Because logs are often accessible to administrators or other privileged users, any party with access to these logs could extract the authentication token and reuse it to impersonate legitimate users or systems, potentially bypassing normal authentication controls. The CVSS v4.0 score is 4.6 (medium severity), reflecting that exploitation requires local access (AV:L), low attack complexity (AC:L), no user interaction (UI:N), and high privileges (PR:H). The impact on confidentiality is low to moderate, as the token exposure could lead to unauthorized access, but the scope is limited by the need for privileged access to logs. There are no known exploits in the wild, and no patches are currently linked, indicating that mitigation relies on configuration changes and access controls until updates are released. This vulnerability highlights the importance of secure logging practices, especially for sensitive authentication data.

For European organizations, the exposure of authentication tokens in logs can lead to unauthorized access to critical integrated systems, potentially compromising confidentiality and integrity of sensitive data. Although exploitation requires high privileges and local access, insider threats or attackers who have gained elevated access could leverage this vulnerability to escalate privileges or move laterally within networks. This risk is particularly significant for sectors with stringent security requirements such as finance, healthcare, and government agencies. The vulnerability could undermine trust in Secure Access deployments, disrupt secure authentication workflows, and increase the attack surface. Organizations relying heavily on Absolute Security's Secure Access for remote or secure access management may face increased risk of credential theft and subsequent unauthorized system access if logs are not properly secured or sanitized.

European organizations should immediately audit and restrict access to log files generated by Secure Access to only the minimum necessary personnel. Review and adjust logging configurations to ensure authentication tokens are redacted or not logged at all. Implement strict file system permissions and monitoring on log storage locations to detect unauthorized access attempts. Until patches or updates are available, consider upgrading to Secure Access versions 14.20 or later once released by Absolute Security. Employ additional compensating controls such as multi-factor authentication (MFA) on integrated systems to reduce the impact of token compromise. Conduct regular security awareness training for administrators regarding secure log handling. Finally, establish incident response procedures to quickly revoke and rotate authentication tokens if exposure is suspected.
