Is the Rumored Spring “Super” Vulnerability Real? What You Need to Know

Yesterday a tweet about a "big Spring vulnerability" was deleted after concerns it might violate platform rules, prompting many questions.

Rumors started on March 29 when a security enthusiast shared that a severe vulnerability had been discovered in the Java ecosystem, with some comparing its impact to Log4j.

Further details from another security researcher narrowed the affected scope to projects using Java 9+ and Spring .

Subsequent speculation linked the issue to a recent Spring commit that addressed an RCE problem. The commit can be examined here:

https://github.com/spring-projects/spring-framework/commit/7f7fb58dd0dae86d22268a4b59ac7c72a6c22529

However, official sources identified the referenced vulnerability as CVE-2022-22963, which is not as severe as the rumors suggested. The CVE details are available at:

Discussion on the Spring issue clarified that the reported change does not constitute a CVE in the core framework; it merely warns about unsafe deserialization using SerializationUtils. The Spring security policy advises reporting genuine issues via https://spring.io/security-policy.

Summary

Spring's officially reported vulnerability is not critical; updating to the patched version suffices.

The rumored "super" vulnerability may be unrelated to the official advisory.

Some marketing articles distribute risky download files; exercise caution.
