Affects: 5.3.x

Please upgrade snakeyaml to 2.0 in branch 5.3.x, e.g. or take 9712bb6

This would help many projects to get free of CVE blaming regarding snakeyaml

SnakeYaml is an optional dependency for Spring Framework. The commit you're pointing out merely raises the minimum version and changes an implementation to avoid deprecation warnings.

Is there a runtime issue with SnakeYaml 2.0 and Spring Framework 5.3.x? Can you report the stacktrace here and a minimal application reproducing the problem? Note that Spring Boot 2.7.x is already targeting SnakeYaml 2.0 compatibility (see spring-projects/spring-boot#34405) and it is based on Spring Framework 5.3.x.

as far as I have understood snakeyaml the change from
https://github.com/spring-projects/spring-framework/blob/main/spring-beans/src/main/java/org/springframework/beans/factory/config/YamlProcessor.java#L184-L189 should work also with 1.33 but is then also compatible with 2.0
