A recent security report identified a vulnerability in Solana's ZK ElGamal program related to its confidential token system. Engineers quickly responded by releasing the necessary patches.
Detection of Vulnerability
In April 2025, a security report submitted to the Anza GitHub repository outlined a potential flaw in Solana's ZK ElGamal Proof program. The report included a proof of concept demonstrating how an attacker could create invalid proofs that the program might accept. Engineers from Anza, Firedancer, and Jito confirmed the issue within hours.
Response and Patches
By the evening of April 18, teams from Solana Foundation and Jito began privately distributing fixes to validator operators. A second related flaw was identified later that night, prompting another update. Both patches underwent review by security firms before reaching validators. By April 18, over two-thirds of the network's validators had implemented the fixes, ensuring the blockchain's security.
Current Market Situation for Solana
As of now, Solana (SOL) is trading at $146.27, showing a 0.88% decrease in the last 24 hours. Its market capitalization stands at approximately $75.77 billion. Although SOL has shown an increase of 18.6% over the past 30 days, recent corrections signal possible consolidation.
The incident underscores the importance of security in cryptographic systems. The resolution of the vulnerability was made possible by the rapid response of the community, highlighting the effectiveness of collaborative efforts in decentralized environments.
