CVE-2025-29072

7.5 highEPSS 0.5%

High (7.5) in nethermind juno. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/NethermindEth/juno 0.12.5.

An integer overflow in Nethermind Juno before v.12.05 within the Sierra bytecode decompression logic within the "cairo-lang-starknet-classes" library could allow remote attackers to trigger an infinite loop (and high CPU usage) by submitting a malicious Declare v2/v3 transaction. This results in a denial-of-service condition for affected Starknet full-node implementations.
