Sonarr
Monthly
Sonarr, a PVR application for Usenet and BitTorrent users, contains an unauthenticated path traversal vulnerability on Windows systems that allows remote attackers to read arbitrary files accessible to the Sonarr process. Affected versions include all 4.x branch releases prior to 4.0.17.2950 (nightly/develop) or 4.0.17.2952 (stable/main). With a CVSS score of 8.6 and network-based unauthenticated access (AV:N/PR:N), this represents a significant confidentiality risk allowing attackers to extract API keys, database credentials, and sensitive system files from Windows installations.
Sonarr, a PVR application for Usenet and BitTorrent users, contains an authentication bypass vulnerability affecting installations configured with authentication disabled for local addresses. Attackers can exploit this flaw to gain unauthorized access to Sonarr instances when deployed without a properly configured reverse proxy that filters malicious headers. The vulnerability affects versions prior to 4.0.16.2942 (nightly/develop) and 4.0.16.2944 (stable/main), with patches now available from the vendor.
