CVE-2026-49130Public exploitNetwork attack vector

Protocol-field injection via unchecked XSPF location

Published May 28, 2026 · Updated May 28, 2026

CRLF injection in Music Player Daemon before 0.24.11 allows remote attackers to forge MPD protocol fields through a malicious XSPF playlist. The xspf_char_data callback appends Expat-decoded numeric character references to a location URI without rejecting CR or LF bytes, which then reach protocol and state-file writers as raw line delimiters. An unauthenticated client that can make MPD load an attacker-controlled playlist can falsify song metadata seen by clients and downstream consumers.
