CVE-2016-8624: Haxx Curl

High severity, CVSS 7.5. EPSS: 6.3% chance of exploitation in the next 30 days.

curl before version 7.51.0 doesn't parse the authority component of the URL correctly when the host name part ends with a '#' character, and could instead be tricked into connecting to a different host. This may have security implications if you for example use an URL parser that follows the RFC to check for allowed domains before using curl to request them.

Affected products

• Haxx Curl: before 7.51.0 (fixed in 7.51.0)
