ColossusCoinXT through 1.0.5 (a chain-based proof-of-stake cryptocurrency) allows a remote denial of service, exploitable by an attacker who acquires even a small amount of stake/coins in the system. The attacker sends invalid headers/blocks, which are stored on the victim's disk.

Security readout for executives and security teams

This issue affects ColossusCoinXT cryptocurrency nodes through version 1.0.5. A remote attacker with even a small amount of stake could make a victim store invalid blockchain data, consuming disk space and causing denial of service. The bundle does not show active exploitation. Exposure is limited to systems running ColossusCoinXT nodes or wallets through version 1.0.5. The bundle does not identify broader affected products, packaged distributions, hosted services, or downstream dependencies. Treat this as targeted operational risk for any business process depending on ColossusCoinXT availability. It is not shown as internet-wide critical infrastructure risk, but affected nodes could be disrupted through disk exhaustion. Mitigation focus: Inventory ColossusCoinXT nodes and confirm whether any run version 1.0.5 or earlier.; Check ColossusCoinXT maintainer guidance and the referenced compare for corrective changes.; Upgrade or rebuild only from trusted maintainer sources when a fixed release is confirmed..
