AI finds critical flaw in Solana's signature update risking 433 metadata accounts

An autonomous AI agent discovered a vulnerability in Solana's SIMD-0376 proposal, which aims to modernize its signature verification system by adopting the ZIP-215 standard. This flaw allows signing at the zero address, potentially exposing 433 metadata accounts to unauthorized actions. The vulnerability arises because ZIP-215 relaxes certain security checks to enable batch processing, unlike the current Ed25519 standard. Solana developers must now assess their programs for this risk, while the Solana Foundation has yet to comment publicly on the issue.

The critical flaw in Solana's SIMD-0376 proposal is the story's subject, with Pluang market data showing strong cryptocurrency gains today. For readers following the crypto market, here is Pluang's snapshot as of Sep 18, 2026 03:45 WIB: 46 of 50 major cryptocurrencies rose, while 3 fell. Notable movers include COTI at Rp408 with a 35.88% increase, UNI at Rp136.750 up 20.34%, and KSM at Rp78.417 down 16.66%.
