On April 14, 2026, security firm Innora disclosed two critical vulnerabilities in the Ethereum-based lending protocol Saturn, exposing $35 million in funds. The first vulnerability could freeze withdrawals for 30 days or longer, while the second allows privileged addresses to legally withdraw up to 33.33% per operation. A single exploit could siphon $157,000, with a total potential risk of $4.26 million. Innora noted that over 90% of Saturn’s assets are held off-chain, raising concerns under MiCA and CFT frameworks. The vulnerabilities remain unpatched.

BlockBeats report: On April 14, security firm Innora released a report stating that the Ethereum-based yield protocol Saturn has two critical vulnerabilities, including:


· Withdrawal freeze vulnerability: Under normal business operations, all user funds could be locked, with a minimum freeze period of 30 days—or indefinitely in extreme cases. No hacker is required; the protocol can trigger this on its own.


The privileged address in the protocol can legally withhold up to 33.33% of funds per operation. Based on current data, this amounts to a maximum of approximately $157,000 per transaction, with a theoretical total risk of up to $4.26 million.


Innora stated that over 90% of Saturn's assets are managed off-chain by a privileged address, leaving users entirely dependent on trust. As of the report's publication, this vulnerability remains unpatched.
