Vulnerability from github – Published: 2026-10-01 18:32 – Updated: 2026-10-01 21:32

Details

Improper validation of FTP PASV reply address in mod_proxy_ftp in Apache Software Foundation Apache HTTP Server through 2.4.68 on all platforms allows, in forward proxy configurations, an untrusted FTP server to cause the proxy to open a data connection to an arbitrary third-party host via a crafted PASV response.

Users are recommended to upgrade to version 2.4.69, which fixes this issue.

Severity

7.5 (High)
