The second vulnerability, CVE-2021-45046, is rated 3.7 out of a possible ten on the CVSS rating system and hinders all versions of Log4j from 2.0-beta9 to 2.12.1 and 2.13.0 to 2.15.0, which the project maintainers shipped last week to address a critical remote code execution vulnerability (CVE-2021-44228) that could be exploited to penetrate and take over systems.
