CVE-2026-14646Network attack vector

Sensitive-data disclosure via unchecked redirect targets

Published Jul 14, 2026 · Updated Jul 14, 2026

SSRF in Sonatype Nexus Repository 3 before 3.94.0 allows remote attackers with repository read access to retrieve protected network content. Proxy repository fetches follow HTTP redirects from configured upstream servers without reapplying the product's SSRF protections to each redirect target. The requester needs repository read access and the upstream must be attacker-controlled or compromised; anonymous access can satisfy the gate and expose internal data or cloud IAM credentials.
