CVE	Sev	Risk	CVSS	EPSS	Published	Description
CVE-2025-46597	Hig	0.49	7.5	0.00	Mar 20, 2026	Bitcoin Core 0.13.0 through 29.x has an integer overflow.
CVE-2025-46598	Med	0.34	5.3	0.00	Mar 20, 2026	Bitcoin Core through 29.0 allows a denial of service via a crafted transaction.
CVE-2013-3220		0.01	—	0.07	Aug 2, 2013	bitcoind and Bitcoin-Qt before 0.4.9rc2, 0.5.x before 0.5.8rc2, 0.6.x before 0.6.5rc2, and 0.7.x before 0.7.3rc2, and wxBitcoin, do not properly consider whether a block's size could require an excessive number of database locks, which allows remote attackers to cause a denial of service (split) and enable certain double-spending capabilities via a large block that triggers incorrect Berkeley DB locking.
CVE-2013-5700		0.00	—	0.00	Sep 10, 2013	The Bloom Filter implementation in bitcoind and Bitcoin-Qt 0.8.x before 0.8.4rc1 allows remote attackers to cause a denial of service (divide-by-zero error and daemon crash) via a crafted sequence of messages.
CVE-2013-4627		0.00	—	0.00	Aug 2, 2013	Unspecified vulnerability in bitcoind and Bitcoin-Qt 0.8.x allows remote attackers to cause a denial of service (memory consumption) via a large amount of tx message data.
CVE-2013-4165		0.00	—	0.00	Aug 2, 2013	The HTTPAuthorized function in bitcoinrpc.cpp in bitcoind 0.8.1 provides information about authentication failure upon detecting the first incorrect byte of a password, which makes it easier for remote attackers to determine passwords via a timing side-channel attack.
CVE-2013-3219		0.00	—	0.00	Aug 2, 2013	bitcoind and Bitcoin-Qt 0.8.x before 0.8.1 do not enforce a certain block protocol rule, which allows remote attackers to bypass intended access restrictions and conduct double-spending attacks via a large block that triggers incorrect Berkeley DB locking in older product versions.
CVE-2013-2293		0.00	—	0.01	Mar 12, 2013	The CTransaction::FetchInputs method in bitcoind and Bitcoin-Qt before 0.8.0rc1 copies transactions from disk to memory without incrementally checking for spent prevouts, which allows remote attackers to cause a denial of service (disk I/O consumption) via a Bitcoin transaction with many inputs corresponding to many different parts of the stored block chain.
CVE-2013-2292		0.00	—	0.03	Mar 12, 2013	bitcoind and Bitcoin-Qt 0.8.0 and earlier allow remote attackers to cause a denial of service (electricity consumption) by mining a block to create a nonstandard Bitcoin transaction containing multiple OP_CHECKSIG script opcodes.
CVE-2013-2273		0.00	—	0.00	Mar 12, 2013	bitcoind and Bitcoin-Qt before 0.4.9rc1, 0.5.x before 0.5.8rc1, 0.6.0 before 0.6.0.11rc1, 0.6.1 through 0.6.5 before 0.6.5rc1, and 0.7.x before 0.7.3rc1 make it easier for remote attackers to obtain potentially sensitive information about returned change by leveraging certain predictability in the outputs of a Bitcoin transaction.
CVE-2013-2272		0.00	—	0.00	Mar 12, 2013	The penny-flooding protection mechanism in the CTxMemPool::accept method in bitcoind and Bitcoin-Qt before 0.4.9rc1, 0.5.x before 0.5.8rc1, 0.6.0 before 0.6.0.11rc1, 0.6.1 through 0.6.5 before 0.6.5rc1, and 0.7.x before 0.7.3rc1 allows remote attackers to determine associations between wallet addresses and IP addresses via a series of large Bitcoin transactions with insufficient fees.
CVE-2012-4684		0.00	—	0.01	Mar 12, 2013	The alert functionality in bitcoind and Bitcoin-Qt before 0.7.0 supports different character representations of the same signature data, but relies on a hash of this signature, which allows remote attackers to cause a denial of service (resource consumption) via a valid modified signature for a circulating alert.
CVE-2012-4683		0.00	—	0.01	Sep 14, 2012	Unspecified vulnerability in bitcoind and Bitcoin-Qt allows attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2012-4682.
CVE-2012-4682		0.00	—	0.00	Sep 14, 2012	Unspecified vulnerability in bitcoind and Bitcoin-Qt allows attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2012-4683.
CVE-2012-3789		0.00	—	0.00	Aug 6, 2012	Unspecified vulnerability in bitcoind and Bitcoin-Qt before 0.4.7rc3, 0.5.x before 0.5.6rc3, 0.6.0.x before 0.6.0.9rc1, and 0.6.x before 0.6.3rc1 allows remote attackers to cause a denial of service (process hang) via unknown behavior on a Bitcoin network.
CVE-2012-2459		0.00	—	0.01	Aug 6, 2012	Unspecified vulnerability in bitcoind and Bitcoin-Qt before 0.4.6, 0.5.x before 0.5.5, 0.6.0.x before 0.6.0.7, and 0.6.x before 0.6.2 allows remote attackers to cause a denial of service (block-processing outage and incorrect block count) via unknown behavior on a Bitcoin network.
CVE-2012-1910		0.00	—	0.03	Aug 6, 2012	Bitcoin-Qt 0.5.0.x before 0.5.0.5; 0.5.1.x, 0.5.2.x, and 0.5.3.x before 0.5.3.1; and 0.6.x before 0.6.0rc4 on Windows does not use MinGW multithread-safe exception handling, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted Bitcoin protocol messages.
CVE-2012-1909		0.00	—	0.01	Aug 6, 2012	The Bitcoin protocol, as used in bitcoind before 0.4.4, wxBitcoin, Bitcoin-Qt, and other programs, does not properly handle multiple transactions with the same identifier, which allows remote attackers to cause a denial of service (unspendable transaction) by leveraging the ability to create a duplicate coinbase transaction.
CVE-2011-4447		0.00	—	0.00	Aug 6, 2012	The "encrypt wallet" feature in wxBitcoin and bitcoind 0.4.x before 0.4.1, and 0.5.0rc, does not properly interact with the deletion functionality of BSDDB, which allows context-dependent attackers to obtain unencrypted private keys from Bitcoin wallet files by bypassing the BSDDB interface and reading entries that are marked for deletion.
CVE-2010-5141		0.00	—	0.01	Aug 6, 2012	wxBitcoin and bitcoind before 0.3.5 do not properly handle script opcodes in Bitcoin transactions, which allows remote attackers to spend bitcoins owned by other users via unspecified vectors.
