On behalf of the team and everyone who has contributed, I am pleased to announce that Spring Framework 6.1.6, 6.0.19 and 5.3.34 are available now:

• Spring Framework 6.1.6 ships with 41 fixes and documentation improvements. This version will be shipped with Spring Boot 3.2.5, to be released next week.
• Spring Framework 6.0.19 ships with 14 fixes and documentation improvements. This version will be shipped with Spring Boot 3.1.11, to be released next week.
• Spring Framework 5.3.34 ships with 10 fixes and documentation improvements.

The releases address CVE-2024-22262 for "URL Parsing with Host Validation (3rd report)". Important CVEs on popular projects, like the original CVE-2024-22243, often get attention from the security community. We received many reports and helpful feedback about new attack variants over the last weeks. The security of Spring applications is our priority and we will keep addressing vulnerabilities in a transparent and timely fashion.

We are actively working on a new approach that will completely revisit the implementation.

Commercial customers using Spring Boot 2.7 or 3.0 can make use of Spring Boot Hotfix releases 2.7.20.3 and 3.0.15.3. Releases are available now on the Spring commercial artifact repository and can be accessed with a Spring Enterprise Subscription.
