CVE-2026-62334 OpenVM's OpenVmHalo2Verifier self-call can bypass proof verification

OpenVM is a performant and modular zkVM framework built for customization and extensibility. Before 1.7.0 in the 1.x line and in affected 2.0 and 2.1 prereleases, OpenVmHalo2Verifier.verify constructs raw proof calldata from user-controlled proofData, performs a staticcall to addressthis, and...

CVE-2026-33471

nimiq-block contains block primitives to be used in Nimiq's Rust implementation. "SkipBlockProof::verify" computes its quorum check using "BitSet.len", then iterates "BitSet" indices and casts each "usize" index to "u16" "slot as u16" for slot lookup. Prior to version 1.3.0, if an attacker can ge...
