CVE-2026-44076
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsufficient sanitization of volume paths in Netatalk 3.1.0 through 4.4.2 allows a local privileged user to inject OS commands and execute arbitrary code via a crafted volume path.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceCommand injection vulnerability in Netatalk's volume path handling allows a local privileged user to inject OS commands via crafted volume paths, leading to arbitrary code execution. The issue stems from insufficient sanitization of user-supplied volume path data in Netatalk versions 3.1.0 through 4.4.2.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Netatalk is installedCheck for the presence of the Netatalk daemon by looking for the 'afpd' process or netatalk binary (e.g., run 'ps aux | grep afpd' or check for /usr/sbin/afpd)Affected if Netatalk is running or the binary exists on the system
-
Determine installed Netatalk versionRun 'netatalk -V' or 'afpd -V' to retrieve the version number, then compare against the affected range 3.1.0 to 4.4.2Affected if The installed version falls within 3.1.0 through 4.4.2 (inclusive)
-
Locate Netatalk volume configurationFind the configuration file defining volumes - common locations are /etc/netatalk/afp.conf or files under /etc/netatalk/AppleVolumes, check the 'volume' or 'path' directivesAffected if Volume configurations exist and define custom volume paths
-
Check configuration file permissionsList permissions on the volume configuration files (e.g., 'ls -la /etc/netatalk/afp.conf') to determine if unprivileged users can write to themAffected if Configuration files are writable by users other than root or the netatalk administrator
The system is affected if Netatalk is installed with a version between 3.1.0 and 4.4.2 and volume configurations exist with permissions allowing modification by untrusted users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Netatalk to version 4.4.3 or later which contains the patched code that properly sanitizes volume paths before processing.
Upgrade to a Netatalk version newer than 4.4.2 (e.g., latest stable 4.x release)
- 1. Identify the currently installed Netatalk version using 'netatalk -V' or checking the package manager
- 2. Plan maintenance window as upgrade may require service restart
- 3. Backup current configuration files in /etc/netatalk/
- 4. Stop the Netatalk service: 'systemctl stop netatalk' or 'service netatalk stop'
- 5. Upgrade Netatalk package via package manager (e.g., 'apt update && apt upgrade netatalk' or 'yum update netatalk')
- 6. Verify the new version is greater than 4.4.2
- 7. Restart Netatalk service: 'systemctl start netatalk' or 'service netatalk start'
- 8. Review volume configurations to ensure no unsafe character sequences remain in volume path definitions
