An update that fixes one vulnerability is now available.
This update for logback fixes the following issues:
Upgrade to version 1.2.8
+ In response to log4Shell/CVE-2021-44228, all JNDI lookup code in logback has been disabled until further notice. This impacts ContextJNDISelector and insertFromJNDI element in configuration files. + Also in response to log4Shell/CVE-2021-44228, all database (JDBC) related code in the project has been removed with no replacement. + Note that the vulnerability mentioned in LOGBACK-1591 requires write access to logback's configuration file as a prerequisite. The log4Shell/CVE-2021-44228 and LOGBACK-1591 are of different severity levels. A successful RCE requires all of the following conditions to be met: - write access to logback.xml - use of versions lower then 1.2.8 - reloading of poisoned configuration data, which implies application restart or scan="true" set prior to attack
