Sonatype: >> Nexus Repository Manager >> 3.92.3 Security Vulnerabilities
Nexus Repository 3 contained a privilege escalation vulnerability in the REST privileges API. An authenticated user with permission to manage privileges could, under certain role configurations, escalate their own access to full administrator by exploiting a type-confusion flaw in the privilege update endpoint.

Nexus Repository 3 does not validate the destination of the "Webhook: Global" capability's configured URL before making an outbound HTTP request, allowing a user holding the Capability Administration permission to cause the server to send requests to internal network locations (Server-Side Request Forgery). This permission is granted by role assignment, independent of authentication status, so an unauthenticated user could also trigger this behavior if the anonymous role has been granted the permission.

Nexus Repository 3 did not apply its existing Server-Side Request Forgery (SSRF) protections to HTTP redirect targets returned by proxy repository upstream servers. Any user with read access to a proxy repository backed by an attacker-controlled or compromised upstream server — including an anonymous user, if anonymous access is enabled — could receive a response from an internal network address or cloud metadata endpoint as repository content, potentially exposing sensitive information such as cloud IAM credentials.

A vulnerability in Sonatype Nexus Repository Manager's format-specific API key generation may allow a remote attacker to gain unauthorized access to repository operations as a targeted user. A format-specific API key realm (NuGet API Key, Docker Bearer Token, or npm Bearer Token) must be enabled and the targeted user must have an active API key for this vulnerability to be exploitable.

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.
