| CVE-2023-30541 | Med | 0.28 | 5.3 | 0.01 | Apr 17, 2023 | OpenZeppelin Contracts is a library for secure smart contract development. A function in the implementation contract may be inaccessible if its selector clashes with one of the proxy's own selectors. Specifically, if the clashing function has a different signature with… | ||
| CVE-2022-35915 | Med | 0.28 | 5.3 | 0.01 | Aug 1, 2022 | OpenZeppelin Contracts is a library for secure smart contract development. The target contract of an EIP-165 `supportsInterface` query can cause unbounded gas consumption by returning a lot of data, while it is generally assumed that this operation has a bounded cost. The issue… | ||
| CVE-2023-34459 | Med | 0.27 | 5.3 | 0.00 | Jun 16, 2023 | OpenZeppelin Contracts is a library for smart contract development.

| CVE-2023-34234 | Med | 0.27 | 5.3 | 0.01 | Jun 7, 2023 | OpenZeppelin Contracts is a library for smart contract development. By frontrunning the creation of a proposal, an attacker can become the proposer and gain the ability to cancel it. The attacker can do this repeatedly to try to prevent a proposal from being proposed at all.… | ||
| CVE-2022-35916 | Med | 0.27 | 5.3 | 0.01 | Aug 1, 2022 | OpenZeppelin Contracts is a library for secure smart contract development.
