| CVE-2023-50428 | 2 Bitcoin, Bitcoinknots | 2 Bitcoin Core, Bitcoin Knots | 2024-01-04 | N/A | 5.3 MEDIUM |
| 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." | |||||
| CVE-2019-15947 | 1 Bitcoin | 1 Bitcoin Core | 2022-05-03 | 5.0 MEDIUM | 7.5 HIGH |
| In Bitcoin Core 0.18.0, bitcoin-qt stores wallet.dat data unencrypted in memory. Upon a crash, it may dump a core file. If a user were to mishandle a core file, an attacker can reconstruct the user's wallet.dat file, including their private keys, via a grep "6231 0500" command. | |||||
| CVE-2021-3195 | 1 Bitcoin | 1 Bitcoin Core | 2021-03-08 | 5.0 MEDIUM | 7.5 HIGH |
| ** DISPUTED ** bitcoind in Bitcoin Core through 0.21.0 can create a new file in an arbitrary directory (e.g., outside the ~/.bitcoin directory) via a dumpwallet RPC call. NOTE: this reportedly does not violate the security model of Bitcoin Core, but can violate the security model of a fork that has implemented dumpwallet restrictions. | |||||
| CVE-2020-14198 | 1 Bitcoin | 1 Bitcoin Core | 2020-09-30 | 5.0 MEDIUM | 7.5 HIGH |
| Bitcoin Core 0.20.0 allows remote denial of service. | |||||
