DescriptionCVE.org

An authorization bypass in Nexus Repository 3's component upload API allowed a user with only read/browse privileges on a Swift, Terraform, or Conda hosted repository to upload arbitrary artifacts, bypassing the intended write-permission check.

AnalysisAI

Authorization bypass in Sonatype Nexus Repository 3's component upload API lets an account holding only read/browse privileges on a Swift, Terraform, or Conda hosted repository push arbitrary artifacts, defeating the intended write-permission check (CWE-862). The flaw affects the specific upload paths for these three formats and enables unauthorized artifact publishing that can poison downstream builds. No public exploit identified at time of analysis; Sonatype has shipped a fix in release 3.94.0.
