CVE-2026-44063 Details
Description
An LDAP injection vulnerability in Netatalk 2.1.0 through 4.4.2 allows a remote authenticated attacker to manipulate LDAP queries and obtain limited information or modify LDAP entries via crafted filter input.
A vulnerability allowing LDAP filter injection has been identified in Netatalk versions 2.1.0 through 4.4.2. This issue arises because LDAP lookup filters can incorporate client-influenced name values without proper escaping. In deployments using LDAP for access control lists or identity mapping, this could lead to authorization or lookup errors.
Users can upgrade to Netatalk version 4.5.0 or later, which includes the necessary patch. For those using Netatalk 4.4.2, the patch can be applied manually. The Netatalk team advises against applying the patch to existing deployments before upgrading, due to the low likelihood of practical exploitation.
