CVE-2026-50268
Published:June 17, 2026
Updated:June 28, 2026
Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Configuration.Encryption 4.0.0 through 4.1.0, configuring "encrypt:rsa:algorithm=OAEP" does not enable OAEP encryption. Due to an incorrect BouncyCastle transformation string, the "OAEP" setting selects PKCS#1 v1.5, which is the same algorithm as the "DEFAULT" setting. Steeltoe.Configuration.Encryption version 4.2.0 patches the issue.
