Solana developers, validators, and client teams have successfully patched a critical security vulnerability on the network, securing the blockchain before disclosing the information to the public.
Solana validator Laine stated on X that a “critical security vulnerability” was addressed by ecosystem participants. The company received messages on August 7 from multiple Solana Foundation members advising of an upcoming critical patch and a hashed message with the incident’s unique identifier.
Laine explained that prominent members of Anza, Jito, and the Solana Foundation published the hash on various platforms to confirm the message’s authenticity. The communication included a specific date and time for applying the patch to mainnet nodes urgently to protect the network.
According to Laine, the vulnerability could have potentially led to a network outage. The patch itself clarifies the nature of the flaw, which is why it was not disclosed earlier. If leaked, an attacker could have attempted to reverse engineer the vulnerability and potentially “halt the network.”
To mitigate risks, the patch was only communicated between trusted parties and released simultaneously for coordinated upgrades. Once 70% of the network was patched and deemed safe, the vulnerability was finally disclosed to the public.
This preemptive action comes in the wake of past criticisms regarding Solana’s network outages. Earlier this year, the network experienced significant downtime, with block production halted for over five hours. The incident impacted crypto exchanges, leading some to suspend deposits and withdrawals of Solana-based tokens.
Critics have pointed to the network’s lack of client diversity as a contributing factor to previous outages.
In April, Solana developers released update version 1.17.31 to address severe network congestion caused by heavy meme coin trading. At the time, Solana Foundation strategy lead Austin Federa acknowledged that the protocol remains in a beta phase, emphasizing that the current network does not represent its final form.
The Solana Foundation also removed several operators in June from its delegation program due to their involvement in malicious sandwich attacks, enhancing network integrity.
