SCA: security update for web3 (GHSA-5hr4-253g-cpx2)

medium Tenable Cloud Security Plugin ID 439857

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - web3.py allows you to interact with the Ethereum blockchain using Python. From 6.0.0b3 to before 7.15.0
 and 8.0.0b2, web3.py implements CCIP Read / OffchainLookup (EIP-3668) by performing HTTP requests to URLs
 supplied by smart contracts in offchain_lookup_payload["urls"]. The implementation uses these contract-
 supplied URLs directly (after {sender} / {data} template substitution) without any destination validation.
 CCIP Read is enabled by default (global_ccip_read_enabled = True on all providers), meaning any
 application using web3.py's .call() method is exposed without explicit opt-in. This results in Server-Side
 Request Forgery (SSRF) when web3.py is used in backend services, indexers, APIs, or any environment that
 performs eth_call / .call() against untrusted or user-supplied contract addresses. A malicious contract
 can force the web3.py process to issue HTTP requests to arbitrary destinations, including internal network
 services and cloud metadata endpoints. This vulnerability is fixed in 7.15.0 and 8.0.0b2. (CVE-2026-40072)

Solution

Update the web3 library and its related packages to version 7.15.0 or later.
