GHSA-J8H8-75H3-JG53 Fleet has a rate limiting bypass via untrusted client IP headers

Impact Fleet trusted client-supplied IP address headers when determining the source IP for incoming requests. This allowed authenticated and unauthenticated clients to spoof their apparent IP address and bypass per-IP rate limiting controls. Fleet determines a client’s public IP address using HTT...

CVE-2026-44183 Cleanuparr: X-Forwarded-For leftmost parsing allows remote unauthenticated admin takeover when reverse-proxy mode is enabled

Cleanuparr is a tool for automating the cleanup of unwanted or blocked files in Sonarr, Radarr, and supported download clients like qBittorrent. Prior to 2.9.10, TrustedNetworkAuthenticationHandler.ResolveClientIp parses the leftmost entry of the X-Forwarded-For header as the client IP. That entr...

CVE-2026-44183

CVE-2026-44183 affects Cleanuparr prior to 2.9.10. The vulnerability arises because TrustedNetworkAuthenticationHandler.ResolveClientIp uses the leftmost entry of the X-Forwarded-For header as the client IP, which is attacker-controlled since X-Forwarded-For is append-only. An unauthenticated rem...
