If an attacker gains access to Netatalk log files — through a compromised internal account, a misconfigured log pipeline, or a separate vulnerability on the same host — they receive working LDAP credentials with no additional effort. Those credentials can open directory services, file shares, and internal applications across the organization, turning a single log read into a broad network access event. For organizations in regulated industries, exposure of directory credentials may constitute a reportable access control failure, and the lateral movement potential amplifies the blast radius well beyond the Netatalk service itself.
You Are Affected If
You run Netatalk version 2.1.0 through 4.4.2 in your environment (typically on Linux/Unix servers providing AFP file sharing to macOS clients)
Netatalk is configured to authenticate users via LDAP simple-bind
Netatalk log files are readable by accounts beyond root or the dedicated Netatalk service account
Logs are shipped to a centralized log aggregation system with broad read access
You have not yet upgraded to a Netatalk version that resolves CVE-2026-44052
Board Talking Points
A flaw in our file-sharing software writes user login passwords to a log file in readable text, potentially handing attackers the keys to our internal directory.
IT should identify all systems running the affected software and rotate exposed credentials within 48 hours, then apply the vendor patch as soon as it is available.
If no action is taken and an attacker has already read these logs, they may already hold valid credentials that allow them to access internal systems and data undetected.
HIPAA — if Netatalk is used for file sharing in a healthcare environment where LDAP credentials govern access to systems containing protected health information, credential exposure may constitute an access control failure under the HIPAA Security Rule (45 CFR §164.312(d))
SOC 2 — exposure of authentication credentials used to access in-scope systems may represent a failure of the CC6.1 logical access control criteria and require disclosure to auditors
