CVE-2026-24783 is a high-severity vulnerability (CVSS 7.5) affecting the soroban-fixed-point-math library (versions 1.3.0 and 1.4.0) used in Soroban smart contracts. The vulnerability lies within the mulDiv function, which incorrectly handles negative intermediate products and divisors, leading to miscalculated rounding in critical division functions like fixed_div_floor and fixed_div_ceil. This could result in incorrect financial calculations or logic within affected smart contracts. The attack vector is network-based with low attack complexity, requiring no user interaction or privileges, and its impact is primarily on integrity (I:H). While the vulnerability is significant, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or community discussion. Patches are available in versions 1.3.1 and 1.4.1, and no workarounds exist for unpatched versions.
