CVE Published:

Summary

A vulnerability exists in the AsyncResponseWrapperImpl class of Apache Olingo versions 4.0.0 to 4.6.0, where the application processes the Retry-After header improperly. If a malicious server sends a substantially large value in this header, it can result in the Thread.sleep() method being invoked with an excessively long duration, potentially leading to a Denial of Service condition. This vulnerability underscores the importance of validating header values to prevent misuse and maintain system availability.

Affected Version(s)

Olingo 4.0.0 to 4.6.0
