Bumps ch.qos.logback:logback-classic from 1.5.18 to 1.5.21.

Release notes

Sourced from ch.qos.logback:logback-classic's releases.

Logback 1.5.20

2025-10-19 Release of logback version 1.5.20

• Due to potential vulnerabilities associated with dynamic, i.e. runtime, java code compilation and execution (using Janino), the 'condition' attribute within the <if> element is deprecated and will be removed in 2027.

An online migration service is provided to help with the transition.

The <condition> element, new in this version, admits custom PropertyEvaluator as a recommended alternative. See also the updated documentation on conditional configuration.

• Logback-classic's initialization procedure has been simplified by removing the step instantiating a SerializedModelConfigurator. However, it is still possible to set up SerializedModelConfigurator as a custom configurator.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit 930fb15c993a4344bcecc6ba2225c12a2c38e676 associated with the tag v_1.5.20. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.5.19

2025-09-30 Release of logback version 1.5.19

• Disallow "new" operator in the condition attribute of <if> elements. This fixes an ACE vulnerability recorded as CVE-2025-11226.

• At initialization time, slightly better reporting about watched configuration files.

• Softer message regarding usage of ConsoleAppender and its potential impact on performance.

• In ViewStatusMessagesServlet, restrict processing of "Clear" button to POST method. This change was proposed by Ralf Wiebicke who also provided the relevant PR.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit e572d4f87f06674788eb3ca7148e8d1dffc615fa associated with the tag v_1.5.19. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.
