CVE-2026-49129: Music Player Daemon < 0.24.11 SSRF via CurlInputPlugin

Music Player Daemon (MPD) before version 0.24.11 contains a server-side request forgery vulnerability in CurlInputPlugin where CURLOPT_FOLLOWLOCATION is set without CURLOPT_REDIR_PROTOCOLS_STR, allowing unauthenticated attackers to bypass the http/https scheme restriction by causing a malicious HTTP server to redirect to non-HTTP protocols such as gopher, ftp, sftp, ldap, dict, rtmp, or rtsp. Attackers can trigger this vulnerability via MPD commands that initiate URL fetches, including add, readcomments, albumart, readpicture, or load, to interact with internal or restricted network services on systems running libcurl versions prior to 7.85.0.

Security readout for executives and security teams

Plain-English summary

MPD versions before 0.24.11 can be tricked into following a web redirect to services that should be unreachable. An unauthenticated attacker able to send relevant MPD commands could use the server as a network proxy, potentially reaching internal or restricted services. The reported impact is limited to downstream confidentiality, with no direct integrity or availability impact identified.

Executive priority

Schedule prompt remediation, prioritizing externally reachable or broadly accessible MPD servers. The 6.9 CVSS score and SSRF capability justify timely action, but absent evidence of active exploitation and direct integrity or availability impact, this does not currently warrant emergency critical-incident handling.

Technical view

CurlInputPlugin enables redirect following without restricting redirect protocols. On systems using libcurl before 7.85.0, an HTTP or HTTPS request can redirect to protocols including gopher, FTP, SFTP, LDAP, DICT, RTMP, or RTSP. Commands such as add, readcomments, albumart, readpicture, and load can trigger the vulnerable fetch path. MPD 0.24.11 contains the correction.

Likely exposure

Exposure requires MPD before 0.24.11, CurlInputPlugin functionality, libcurl before 7.85.0, and attacker access to commands that initiate URL retrieval. Internet-accessible or insufficiently restricted MPD command interfaces present the clearest risk. The supplied evidence does not quantify deployment prevalence.

Exploitation context

The researcher published technical details, but the supplied sources do not establish attacks in the wild. This CVE is not listed as KEV in the bundle. Exploitation is remotely reachable, low complexity, unauthenticated, and requires no user interaction according to the supplied CVSS 4.0 vector.

Researcher notes

CWE-918 applies. The security boundary fails across redirects: initial HTTP or HTTPS validation does not constrain the redirected protocol. The patch reference indicates redirect-protocol handling was corrected in 0.24.11. The supplied evidence identifies downstream confidentiality impact but does not demonstrate code execution, data modification, service disruption, or observed exploitation.

Mitigation direction

  • Upgrade MPD to version 0.24.11 or later.
  • Prioritize systems exposing MPD command access to untrusted networks.
  • Restrict MPD command access to trusted hosts while upgrades are pending.
  • Check vendor guidance before applying alternative mitigations.

Validation and detection

  • Inventory MPD versions and identify installations earlier than 0.24.11.
  • Record the linked libcurl version and flag versions earlier than 7.85.0.
  • Determine whether CurlInputPlugin and URL-fetching commands are available.
  • Verify untrusted networks cannot reach the MPD command interface.
  • After upgrading, confirm MPD reports version 0.24.11 or later.
