Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
OwnTone Server versions 28.4 through 29.0 contain a SQL injection vulnerability in DAAP query and filter handling that allows attackers to inject arbitrary SQL expressions by supplying malicious values through the query= and filter= parameters for integer-mapped DAAP fields. Attackers can exploit insufficient sanitization of these parameters to bypass filters and gain unauthorized access to media library data.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-89

User input is woven into a database query, letting an attacker rewrite the query's logic. From there they can read, alter, or destroy data — frequently the entire database. The reliable fix is parameterised queries (prepared statements), so input is always treated as data and never as SQL.

Recommended fix Moderate confidence

Latest stable release after version 29.0 (check releases for version incorporating commit d4784ebf)

  1. 1. Identify the current OwnTone Server version by checking the application or package version
  2. 2. Navigate to the OwnTone Server GitHub releases page at https://github.com/owntone/owntone-server/releases
  3. 3. Look for a release version newer than 29.0 that includes the security fix from commit d4784ebf
  4. 4. Download or update to that newer release version
  5. 5. Restart the OwnTone Server service to apply the update
  6. 6. Verify the server is running correctly and test that DAAP functionality works
Caveat Minor - OwnTone Server updates are typically backward compatible with media library configurations
