CVE-2026-0519 is a vulnerability in the Absolute Security Secure Access product, specifically in versions 12.70 and prior to 14.20. The vulnerability stems from the logging subsystem, which under certain configurations may write authentication tokens in an unredacted form to log files. These tokens are sensitive credentials used to authenticate to integrated systems. If an attacker or unauthorized party gains access to these logs, they can extract the tokens and reuse them to impersonate legitimate users or systems, thereby gaining unauthorized access. The vulnerability requires the attacker to have local access to the system logs and high privileges (as indicated by the CVSS vector: Privileges Required: High). No user interaction is needed, and the attack vector is local, limiting remote exploitation. The vulnerability impacts confidentiality by exposing authentication tokens, and integrity by enabling unauthorized access. The CVSS score of 4.6 (medium severity) reflects the limited attack vector and the requirement for high privileges, but the potential for misuse of sensitive tokens. No known exploits have been reported in the wild as of the publication date. The vulnerability affects a specific product widely used for secure access management, which may be integrated into critical infrastructure and enterprise environments. The lack of available patches at the time of reporting necessitates immediate mitigation through configuration review and access controls.

For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of authentication credentials used within Secure Access environments. If exploited, attackers with access to logs could impersonate legitimate users or systems, potentially gaining unauthorized access to sensitive integrated systems. This could lead to data breaches, unauthorized system control, and lateral movement within networks. Organizations in sectors such as finance, government, healthcare, and critical infrastructure that rely on Absolute Security Secure Access for authentication and access management are particularly at risk. The requirement for high privileges and local access reduces the likelihood of widespread exploitation but does not eliminate insider threats or risks from compromised administrative accounts. The exposure of authentication tokens in logs could also facilitate further attacks if logs are not properly secured or if log management systems are accessible by unauthorized personnel. The medium severity indicates a moderate risk that should be addressed promptly to prevent escalation.

1. Immediately review logging configurations in Secure Access to ensure that authentication tokens are not logged in plaintext or unredacted form. 2. Restrict access to log files strictly to authorized personnel and systems, implementing least privilege principles. 3. Conduct an audit of existing logs to identify any exposure of authentication tokens and take remedial actions such as token revocation or password resets. 4. Monitor for unusual access patterns that might indicate misuse of exposed tokens. 5. Apply any available patches or updates from Absolute Security as soon as they are released, prioritizing upgrades to versions 14.20 or later where the vulnerability is fixed. 6. Implement enhanced monitoring and alerting on systems running affected versions to detect potential exploitation attempts. 7. Consider isolating or segmenting systems that generate sensitive logs to limit exposure. 8. Educate administrators and security teams about the risk of sensitive data in logs and enforce secure logging practices.
