CVE-2025-9868Network attack vector

Credential disclosure via attacker-directed remote browsing

Published Oct 8, 2025 · Updated Oct 8, 2025

SSRF in Sonatype Nexus Repository 2.0.0 through 2.15.2 allows remote attackers to disclose proxy credentials via HTTP requests. The default-enabled Remote Browser Plugin accepts an attacker-selected destination and sends an outbound GET that can include configured proxy credentials. No authentication is required, but disclosure requires the plugin and a proxy repository configured with authentication.
