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.
CVE-2026-50268
LOWPre-NVD 1.91.9
EchelonGraph scoreLOW confidence
This low-severity CVE scores 1.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.0%, top 100% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
