Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
October Rain (october/rain) versions before 3.7.14 and from 4.0.0 before 4.1.10 are vulnerable to information disclosure through the INI settings parser. An attacker with Editor access to the backend could inject environment variable references into CMS page settings, causing values such as application keys or database credentials to be stored and shown back to them when the page is reopened. Upgrade to 3.7.14 or 4.1.10. If upgrading is not possible, restrict Editor access to fully trusted administrators.
