CVE-2026-0519
📋 TL;DR
Secure Access versions 12.70 through 14.20 may write unredacted authentication tokens to logs under certain configurations. Attackers with access to these logs could steal tokens and impersonate legitimate users to access integrated systems. This affects organizations using vulnerable Secure Access configurations.

📦 What is this software?
Secure Access by Absolute
⚠️ Risk & Real-World Impact
Worst Case
An attacker with log access steals authentication tokens and gains unauthorized access to integrated systems, potentially leading to data breaches or lateral movement.
Likely Case
Internal users or administrators with log access inadvertently discover tokens and misuse them for unauthorized access to connected systems.
If Mitigated
With proper log access controls and monitoring, token exposure is limited to authorized personnel only.
🎯 Exploit Status
Exploitation requires access to logs containing unredacted tokens, which typically requires some level of system access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 14.20 or later
Vendor Advisory: https://www.absolute.com/platform/security-information/vulnerability-archive/cve-2026-0519
Restart Required: Yes
Instructions:

🔧 Temporary Workarounds
Enable Token Redaction in Logging
allConfigure logging subsystem to redact authentication tokens in all log outputs.
# Check current logging configuration
# Configure token redaction via Secure Access admin interface
Restrict Log Access
linuxImplement strict access controls on log files and directories to prevent unauthorized access.
# Set appropriate file permissions on log directories
# chmod 640 /var/log/secure_access/*
# Configure log rotation with secure permissions
🧯 If You Can't Patch
- Implement strict access controls on log storage and transmission
- Enable comprehensive monitoring and alerting for log access attempts
🔍 How to Verify
Check if Vulnerable:
Check Secure Access version and review logging configuration for token redaction settings.Check Version:
# On Secure Access server: secure_access --versionVerify Fix Applied:
Verify version is 14.20 or later and test that authentication tokens are properly redacted in logs.📡 Detection & Monitoring
