CVE-2026-49130 Details
Description
Music Player Daemon (MPD) before version 0.24.11 contains a CRLF injection vulnerability in the xspf_char_data function within the XSPF playlist plugin that allows attackers to embed literal CR/LF bytes in URI fields by supplying a malicious XSPF playlist with XML numeric character references. Attackers can inject forged key-value lines through the location field into MPD protocol responses including playlistinfo, currentsong, and listplaylist outputs, as well as the state file writer, by exploiting Expat's decoding of numeric character references prior to the character data callback.
A CRLF injection vulnerability has been identified in Music Player Daemon (MPD) versions prior to 0.24.11. The issue resides in the XSPF playlist plugin, specifically within the 'xspf_char_data' function. This vulnerability allows attackers to embed literal carriage return and line feed bytes into URI fields by using a malicious XSPF playlist that includes XML numeric character references. Exploitation of this vulnerability involves injecting forged key-value lines through the 'location' field, which are then incorporated into MPD protocol responses such as 'playlistinfo', 'currentsong', and 'listplaylist'. Additionally, the injected data can disrupt the state file writer. The vulnerability arises from Expat's handling of numeric character references, which are decoded before the character data callback, creating an opportunity for injection.
Users can update to MPD version 0.24.11 or later, where this vulnerability has been fixed.
