CVE-2024-23684 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Inefficient algorithmic complexity in DecodeFromBytes function in com.upokecenter.cbor Java implementation of Concise Binary Object Representation (CBOR) versions 4.0.0 to 4.5.1 allows an attacker to cause a denial of service by passing a maliciously crafted input. Depending on an application's use of this library, this may be a remote attacker.. EPSS estimates a 0.91% chance of exploitation in the next 30 days.
