09 Dec 2023 — In Bitcoin Core through 26.0 and Bitcoin Knots before 25.1.knots20231115, datacarrier size limits can be bypassed by obfuscating data as code (e.g., with OP_FALSE OP_IF), as exploited in the wild by Inscriptions in 2022 and 2023. NOTE: although this is a vulnerability from the perspective of the Bitcoin Knots project, some others consider it "not a bug."

06 Jul 2023 — Memory management and protection issues in Bitcoin Core v22 allows attackers to modify the stored sending address within the app's memory, potentially allowing them to redirect Bitcoin transactions to wallets of their own choosing. Los problemas de gestión de memoria y protección en Bitcoin Core v22 permiten a los atacantes modificar la dirección de envío almacenada en la memoria de la aplicación, lo que potencialmente les permite redirigir las transacciones de Bitcoin a los monederos de su elección. • https://bitcoin.org/en/bitcoin-core • CWE-311: Missing Encryption of Sensitive Data •

22 May 2023 — Bitcoin Core before 24.1, when debug mode is not used, allows attackers to cause a denial of service (e.g., CPU consumption) because draining the inventory-to-send queue is inefficient, as exploited in the wild in May 2023. A vulnerability has been discovered in Bitcoin, which can lead to a denial of service. Versions greater than or equal to 25.0 are affected. • https://en.bitcoin.it/wiki/Common_Vulnerabilities_and_Exposures • CWE-400: Uncontrolled Resource Consumption •

16 Mar 2020 — Bitcoin Core before 0.14 allows an attacker to create an ostensibly valid SPV proof for a payment to a victim who uses an SPV wallet, even if that payment did not actually occur. Completing the attack would cost more than a million dollars, and is relevant mainly only in situations where an autonomous system relies solely on an SPV proof for transactions of a greater dollar amount.
