In Netatalk 3.0.2 through 4.4.2, arbitrary file read via attacker-controlled symlink creation. Fixed in 4.4.3.
AnalysisAI
Arbitrary file read in Netatalk 3.0.2 through 4.4.2 allows authenticated remote attackers to create attacker-controlled symbolic links that the AFP server follows, exposing sensitive files outside the intended share. The flaw is fixed in version 4.4.3 and no public exploit identified at time of analysis. Securin reported the issue and the vendor has published an advisory at netatalk.io.
Technical ContextAI
Netatalk is an open-source implementation of the Apple Filing Protocol (AFP) that lets Unix-like systems serve files to macOS clients over the network. The root cause is CWE-59 (Improper Link Resolution Before File Access, a.k.a. Link Following): the daemon resolves symbolic links created by an authenticated user without enforcing that the resolved path remains inside the share boundary, so a crafted symlink pointing to /etc/shadow, configuration files, or other private paths is dereferenced server-side and the contents are returned to the client. The affected CPE is cpe:2.3:a:netatalk:netatalk for all 3.0.2-4.4.2 builds.
RemediationAI
Upgrade to Vendor-released patch: Netatalk 4.4.3, which contains the fix; consult the upstream advisory at https://netatalk.io/security/CVE-2026-44051 for build notes. Until packaged updates are available for your distribution, reduce exposure by restricting AFP access (TCP/548) to trusted networks via host or network firewall, disabling AFP shares that accept untrusted authenticated users, and removing or tightening shares where 'follow symlinks' style options are enabled in afp.conf - note that disabling symlink following may break legitimate macOS Time Machine or shared-mount workflows that rely on it. Where feasible, migrate clients to SMB on Samba as a longer-term alternative, accepting the operational cost of changing the file-sharing stack.
