CVE-2021-46320 affects OpenZeppelin versions up to 4.4.0, specifically impacting initializer functions in smart contracts. The vulnerability allows for reentrancy in initializer functions that make untrusted external calls, particularly when invoked separately from contract creation, such as with minimal proxies. Rated 7.5 HIGH, this flaw has a low attack complexity and can lead to high integrity impacts, as it breaks the expectation of single execution for initializers. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
