Release Notes

ethers-io/ethers.js (@​ethersproject/contracts)

v5.8.0: ethers/v5.8.0 (2025-02-25 19:15) [legacy version]

Compare Source

This is a security update for the legacy Ethers v5 branch, addressing two security fixes.

• A bug in elliptic, which does not affect ethers but triggers a critical security warning during nom audit [see: missing signature length check, missing check for leading bit, allow BER-encoded signatures, false negative verification, signing malformed input]
• A bug in ws which can be used as DoS vector when communicating with malicious WebSocket service providers, triggering a high security warning during nom audit [see: too many HTTP headers]

For those that wish to audit the specific changes in the the bundled version between v5.7 and v5.8, see this gist.

Changes

• Updated to latest elliptic library to fix audit warnings. (f8deaae)
• Added ENS to Sepolia. (0065547)
• Bump ws package version to address DoS security concern. (#​4791; f345816)
• Added modern networks, updated third-party backend URLs and added QuickNode. (#​3935, #​4010; f7c813d)
