CVE-2026-44068 Details
Description
Incomplete sanitization of extended attribute (EA) path components in Netatalk 2.1.0 through 4.4.2 allows a remote authenticated attacker to write to files outside the intended metadata namespace via crafted EA names.
A path traversal vulnerability has been identified in Netatalk versions 2.1.0 through 4.4.2. This issue arises from incomplete sanitization of extended attribute names during file operations, allowing an authenticated AFP user to manipulate files within their filesystem permissions. The vulnerability is particularly relevant when extended attributes are stored as AppleDouble files, where some operations fail to properly restrict client-controlled names to the designated metadata namespace.
Users can upgrade to Netatalk version 4.4.3 or later, which includes the necessary patch. Alternatively, the patch for this vulnerability can be applied to a Netatalk 4.4.2 source tree. Netatalk administrators are advised to take action as soon as possible.
