Threats affecting pkg:maven/sonatype/nexus_repository_manager

CVE-2026-97667 is a medium severity cross-site scripting (XSS) vulnerability in Sonatype Nexus Repository 3. It allows a user with edit permission on a hosted R repository to inject script content into the metadata of an uploaded R package. This script executes in the browser of any user who views the package details, running with the permissions of the viewing user. Both authenticated and anonymous users (if granted permission) can exploit this. The vulnerability affects versions from 3.28.0 up to but not including 3.97.0.

Nexus Repository 3 was found to be vulnerable to stored cross-site scripting (XSS). A user with the nexus:blobstores:create or nexus:blobstores:update permission could set a blob store name containing malicious script content, which would later execute in the browser of another user viewing system health-check status. This issue has been fixed in version 3.95.0.

Sonatype Nexus Repository 3 did not properly filter internal configuration keys from user-supplied task properties when creating or updating a scheduled task through the administrative UI. An account holding permission to create at least one scheduled task type could supply a crafted property value that caused the system to overwrite the configuration of an unrelated, existing task instead of creating a new one.

Nexus Repository 3 contained an endpoint used to change the administrator account password during initial onboarding. This endpoint did not verify that onboarding was still in progress before allowing the password change, relying instead on the presence of a local onboarding artifact. As a result, an account holding the nexus:* permission could invoke the endpoint outside the intended onboarding flow to replace the administrator password, and existing sessions were not invalidated after the change.

A user holding a permission to update privilege definitions could modify a wildcard privilege already assigned to their own role to grant broader permissions than they were authorized to hold, including full administrative access, without any additional authorization check or role reassignment.

Nexus Repository 3 contains a Server-Side Request Forgery (SSRF) vulnerability in the email configuration verification feature. A user holding the nexus:settings:update permission could submit arbitrary host and port values to the email test/verification endpoint, causing the server to attempt outbound network connections to internal or otherwise restricted network addresses. Differences in the server's response could be used to infer whether internal hosts and ports are reachable. This issue affects Nexus Repository 3 CE/Pro versions up to and including 3.94.1, and is fixed in version 3.95.0.

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.

Sonatype Nexus Repository Manager before 3.93.0 contains an authorization vulnerability in the proxy repository configuration that allows a delegated repository administrator to disclose stored upstream proxy credentials.

An authenticated user with the nx-licensing-create privilege can upload a specially crafted license file to execute arbitrary operating system commands as the Nexus process user in Sonatype Nexus Repository 3 versions before 3.92.0.
