Web3.py 7.15.0 through 7.16.0 and 8.0.0b2 through 8.0.0 contains a server-side request forgery vulnerability because _check_ip_blocked() does not unwrap IPv4-mapped IPv6 addresses in CCIP Read URL validation. Malicious contracts can return OffchainLookup URLs with IPv4-mapped IPv6 hosts or AAAA records, making clients with CCIP Read enabled send requests to loopback, private, or link-local services.

CVE-2026-755907.2 ALT—
———IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to access internal network resources and obtain sensitive information due to server-side request forgery. A protection that blocks requests to internal addresses can be bypassed, so the server could be made to contact internal services and return part of their responses.5hCVE-2026-191287.5 ALT—
———IBM API Connect 12.1.0.0 through 12.1.1.2 could allow an authenticated attacker to send unauthorized requests from the system due to server-side request forgery. This could be used to enumerate network resources or to support further attacks.5hCVE-2026-191223.8 BAI—

———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote attacker to obtain sensitive information due to server-side request forgery. The affected component can be made to send requests to unintended destinations and return the response to the attacker.5hCVE-2026-174068.5 ALT—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to server-side request forgery. Address checks can be bypassed, which could allow the server to reach destinations that should be blocked.5hCVE-2026-174048.5 ALT—
