Spring Framework RCE 0‑Day Vulnerability Triggered by Java Serialization
A recent Spring Framework 0‑day remote code execution vulnerability, caused by unsafe use of SerializationUtils#deserialize, affects Java versions above 8, is rated dangerous by security analysts, and highlights the risks of indiscriminate JDK upgrades.
Hello everyone, I’m the author sharing a recent "melon" I found: Spring has unintentionally contributed a security issue.
While some were joking about whether the issue is as tasty as Log4j2, the reality is that a closed GitHub issue titled RCE 0 Day #28248 actually points to a serious vulnerability.
Research confirms that Spring Framework suffers from a remote code execution (RCE) 0‑day vulnerability caused by the use of SerializationUtils#deserialize , which exploits Java's native serialization mechanism.
Security media FreeBuf has rated this vulnerability as dangerous .
The mitigation is straightforward: environments running JDK 8 or lower are not affected. Running java -version on a server shows that using Java 8 remains safe.
Newer Java releases (e.g., Java 18) do not automatically protect against this issue, so developers should be cautious when upgrading.
Compared to the Log4j2 incident, this Spring vulnerability is less severe but still noteworthy.
Overall, the incident serves as a reminder: do not upgrade your JDK version without verifying compatibility and security implications.
