Improper Input Validation in Jenkins
Jenkins versions 2.88 and earlier and 2.73.2 and earlier stores metadata related to 'people', which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping, potentially resulting in problems like overwriting of unrelated configuration files.
