Nexus Repository - Arbitrary Class Instantiation via Unsafe Realm Configuration

An account holding the nexus:settings:update permission in Nexus Repository 3 (or the equivalent nexus:settings permission in the legacy Nexus Repository 2) could submit arbitrary values as realm identifiers through an internal configuration API that did not validate them against the set of registered realms. Because unrecognized entries were persisted and re-evaluated on every realm load via a legacy code path, this could result in unintended code executing inside the Nexus Repository process, …

Nexus Repository - SSRF in SSL Certificate Retrieval

Nexus Repository 3 is vulnerable to Server-Side Request Forgery (SSRF) via the SSL Certificate Retrieval endpoint. A user holding the nexus:ssl-truststore:read permission could cause the server to initiate outbound connections to internal or otherwise restricted network hosts. This issue affects Nexus Repository 3.0.0 through versions prior to 3.94.0.

Nexus Repository 3 - Stored Cross-Site Scripting (XSS) via HTML Browse Page

An authenticated user with upload permission to a hosted repository can store content that causes arbitrary JavaScript to execute in the browser of any user who browses that repository directory via the HTML index page in Sonatype Nexus Repository versions 3.6.0 through versions before 3.92.0. This could allow the attacker to perform actions in the context of the victim's session.
