GEM

private_address_check

SEVERITY

CVSS v3.x: 8.1 (High)

CVSS v2.0: 6.8 (Medium)

PATCHED VERSIONS

• >= 0.4.0

DESCRIPTION

The private_address_check ruby gem before 0.4.0 is vulnerable to a bypass due to use of Ruby's Resolv.getaddresses method, which is OS-dependent and should not be relied upon for security measures, such as when used to blacklist private network addresses to prevent server-side request forgery.
