Unauthenticated IP blocking bypass via spoofed header
Published Aug 22, 2022 · Updated Aug 3, 2024
Authentication bypass in WordPress Download Manager before 3.2.50 allows remote attackers to access IP-blocked downloads via spoofed headers. The plugin trusts client-controlled forwarding headers such as X-Forwarded-For ahead of PHP REMOTE_ADDR when determining the visitor address, so a crafted request can evade an IP deny rule. No login is required, but a download must be protected by the plugin's IP-based blocking feature; the documented impact is unauthorized file access rather than code execution or service interruption.
