An issue has been discovered affecting GitLab versions prior to 14.4.5, between 14.5.0 and 14.5.3, and between 14.6.0 and 14.6.1. Gitlab's Slack integration is incorrectly validating user input and allows to craft malicious URLs that are sent to slack.
The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.
