Linux Distros Unpatched Vulnerability : CVE-2026-49128

high Nessus Plugin ID 317834

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- Music Player Daemon (MPD) before version 0.24.11 contains a path traversal vulnerability in LocalStorage::MapFSOrThrow and LocalStorage::MapUTF8 within the local storage plugin, where the on-disk path is constructed by joining the storage root with a user-supplied URI as plain strings without canonicalization, allowing '..' segments to survive into the resolved path and be flattened by the kernel at openat() time. An unauthenticated attacker can exploit this flaw using the listfiles command to enumerate names, sizes, and modification times of arbitrary directories readable by the MPD process, and the albumart command to read image files in any attacker-chosen directory outside the configured music_directory. (CVE-2026-49128)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
