Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Contao (contao/core-bundle and contao/contao packages) versions from 5.0.0-RC1 before 5.3.38 and from 5.4.0-RC1 before 5.6.1 are affected. If a news feed includes protected news archives, their news items are not filtered out and appear publicly in the RSS feed, so an unauthenticated visitor can read them. Upgrade to 5.3.38 or 5.6.1. As a workaround, do not add protected news archives to the news feed page.
