Affected packages

• Maven org.jenkins-ci.main:jenkins-core: < 2.263.2 → fixed in 2.263.2 • Maven org.jenkins-ci.main:jenkins-core: >= 2.264, < 2.275 → fixed in 2.275

Description

Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows users with Agent/Configure permission to choose agent names that cause Jenkins to override unrelated `config.xml` files. If the global `config.xml` file is replaced, Jenkins will start up with unsafe legacy defaults after a restart. Jenkins 2.275, LTS 2.263.2 ensures that agent names are considered valid names for items to prevent this problem. In case of problems, this change can be reverted by setting the Java system property `jenkins.model.Nodes.enforceNameRestrictions` to `false`.
