Vulnerability Details CVE-2026-40069
BSV Ruby SDK is the Ruby SDK for the BSV blockchain. From 0.1.0 to before 0.8.2, BSV::Network::ARC's failure detection only recognises REJECTED and DOUBLE_SPEND_ATTEMPTED. ARC responses with txStatus values of INVALID, MALFORMED, MINED_IN_STALE_BLOCK, or any ORPHAN-containing extraInfo / txStatus are silently treated as successful broadcasts. Applications that gate actions on broadcaster success are tricked into trusting transactions that were never accepted by the network. This vulnerability is fixed in 0.8.2.
