CVE-2024-14031 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. Sereal::Encoder versions from 4.000 through 4.009_002 for Perl embeds a vulnerable version of the Zstandard library. Sereal::Encoder embeds a version of the Zstandard (zstd) library that is vulnerable to CVE-2019-11922. This is a race condition in the one-pass compression functions of Zstandard prior to version 1.3.8 could allow an attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used.. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
