CVE-2021-3195

7.5 highEPSS 1.3%

High (7.5) in bitcoin bitcoin core. EPSS 1.3% chance of exploitation in the next 30 days.

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
