A flaw was found in the `mod_dav_fs` module of Apache HTTP Server. A WebDAV (Web Distributed Authoring and Versioning) content author could exploit a path handling issue to directly manipulate trusted DAV property databases. This manipulation could potentially lead to child process crashes, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-06-08 16:02:26 UTC
A path handling issue in mod_dav_fs in Apache 2.4.67 and earlier allows a WebDAV content author to directly manipulate trusted DAV property databases, potentially causing child process crashes.

Users are recommended to upgrade to version 2.4.68, which fixes this issue.
