Odaily Planet Daily News: Bitcoin Core developers have disclosed a high-risk vulnerability numbered CVE-2024-52911, affecting versions 0.14.1 through 28.4. Attackers can exploit this vulnerability by constructing a special block to remotely crash other nodes and execute code. The vulnerability was discovered and privately reported by developer Cory Fields in November 2024. The fix was merged in December 2024 and officially launched in the v29 release in April 2025.

Currently, support for the last vulnerable version in the 28.x series ended on April 19, 2026. However, since upgrading Bitcoin nodes is voluntary, it is estimated that approximately 43% of nodes are still running vulnerable old versions, posing a potential security risk.
