CVE-2026-44052: Netatalk Exposes LDAP Passwords in Logs
The National Vulnerability Database (NVD) has identified CVE-2026-44052, a critical vulnerability affecting Netatalk versions 2.1.0 through 4.4.2. This flaw allows for the exposure of LDAP simple-bind passwords directly within log output. This is a significant risk as it could lead to unauthorized access to sensitive network resources if attackers can pivot to the logs.
The vulnerability, classified as HIGH severity with a CVSS score of 7.5, stems from inadequate handling of sensitive credentials during the authentication process. The National Vulnerability Database notes that fixed versions are available starting with Netatalk 4.4.3. Defenders should prioritize patching or upgrading affected Netatalk instances immediately to mitigate the risk of credential compromise.
What This Means For You
- If your organization uses Netatalk for Apple Filing Protocol services and leverages LDAP for authentication, you must immediately verify your Netatalk version. Patch to 4.4.3 or later to address CVE-2026-44052. Review system logs for any unusual activity or signs of credential exposure related to LDAP binds.
