CVE-2026-113371: Sonatype Nexus Repository 3 signing passphrase disclosure in REST endpoint

CVE-2026-113371 · Severity: info · Published 2026-11-04

Sonatype Nexus Repository 3 is a software package manager that organizations use to host and manage dependencies for their applications. A vulnerability allows users with read-only access to APT or YUM repository settings to retrieve the signing passphrase through an internal API endpoint, exposing a sensitive credential that should require edit privileges to access. An attacker with read-only repository access could use this passphrase to forge or tamper with signed packages.

Technical details

The vulnerability is an information disclosure flaw in Nexus Repository 3's REST API endpoint for APT and YUM repository management. A user account with read-only (view) privileges on a repository configuration can query an internal REST endpoint and retrieve the repository's signing passphrase without requiring edit or administrative privileges. No authentication bypass is needed; the flaw is a broken access control where the API fails to enforce privilege escalation checks.
