What’s New and Noteworthy in This Release?
Support for Proxy Terraform Repositories
Sonatype Nexus Repository now supports proxy repositories for Terraform, enabling users to cache Terraform providers and modules from registry.terraform.io for improved performance, reliability, and governance.
This allows organizations to streamline infrastructure-as-code workflows by hosting provider binaries, checksums, signatures, and module archives directly within Nexus Repository. By rewriting upstream metadata, all download URLs point to your Nexus Repository instance, ensuring consistent access and control over Terraform content across all environments.
Terraform currently requires user token-based authentication, which requires a paid Nexus Repository Pro or Nexus Repository Cloud license. This means that, at the moment, Community Edition users are unable to authenticate for Terraform repositories. Anonymous access is not currently available for Terraform proxy repositories, though that will be enabled shortly.
Nexus Repository is compatible with the Terraform CLI version 0.13 and later, including all 1.x releases. To get started, see our Terraform repository help documentation.
Search Now Powered by SQL Instead of Elasticsearch
Starting in Nexus Repository 3.88.0, all search operations are now executed directly against the underlying SQL database, replacing Elasticsearch across all repository formats and editions.
This change improves consistency and simplifies deployment by using your configured database (i.e., PostgreSQL or H2) for search indexing and queries. While search functionality, API endpoints, and query syntax remain unchanged, some behavior may differ slightly, particularly around wildcard support, fuzzy matching, and relevance ranking.
PostgreSQL is recommended for production environments and supports relevance-based search; H2 is intended for development and may yield reduced performance on large datasets.
For full details, see our SQL Search help documentation.
Trigram Module Required for PostgreSQL
Reminder that it is required to have the pg_trgm (trigram) module installed when using a PostgreSQL database. This module may not be installed with PostgreSQL by default on all Linux distributions, which will result in an exception when attempting to upgrade.
New API to Retrieve Capability Types and Metadata
This releaseadds a new GET /v1/capabilities/types API endpoint that allows you to programmatically retrieve all available capability types along with their metadata, such as form fields, descriptions, and configuration requirements. This is useful for automating or dynamically generating capability-related configurations in external tools or custom UIs.
For full details, see the Capabilities API help documentation.
New Capability and Task for Managing Browse Tree Cleanup
Sonatype Nexus Repository 3.88.0 introduces a new Repository: Browse Trim capability and a Repair - Repository trim browse tree task to give administrators more control over cleaning up empty browse nodes (folders) after component deletion.
Automatic trimming is always enabled for H2 databases but disabled by default for PostgreSQL. For PostgreSQL users who prefer to keep automatic trimming disabled, the new repair task offers a manual alternative to clean up empty nodes on demand.
Learn more in the capability and task documentation.
Configurable Interation Settings for Password and Secret Encryption
Sonatype Nexus Repository 3.88.0 adds support for two new properties (nexus.security.password.iterations and nexus.security.secrets.iterations) that allow administrators to configure the number of PBKDF2 iterations used when encrypting user passwords and sensitive secrets like API keys and tokens.
These properties, set in the nexus.properties file, provide greater control over encryption strength and support seamless migration to updated security configurations.
See our Re-encryption in Nexus Repository help documentation for full details.
New URL Validation to Protect Against Private Network Access
Sonatype Nexus Repository 3.88.0 introduces optional URL validation to help protect against Server-Side Request Forgery (SSRF) by blocking outbound connections to private network addresses, localhost, or cloud metadata endpoints.
This validation applies to Remote Storage URLs for proxy repositories and Endpoint URLs for Amazon S3 blob stores. By default, private network access remains allowed, but administrators can restrict it by setting nexus.proxy.allowPrivateNetworks=false in the nexus.properties file or using environment variables.
For full details, see Securing Nexus Repository.
Important Change Coming in 3.90.0
Starting in version 3.90.0, private network access will be blocked by default.
Updated SAML Library for Improved Security and Compatibility
Sonatype Nexus Repository now uses a new library for handling SAML authentication. This update aligns with our ongoing efforts to improve security and maintain compatibility with modern identity providers (IdPs). We have tested this change internally with a range of IdPs, but we recommend validating your SAML configuration in a test environment before deploying to production.
Note
If your IdP includes an entityId in its SAML response, it must match the entityId configured in Nexus Repository for authentication to succeed. This behavior may differ from previous versions.
Repair - Execute Data Repair Plan Task Disabled by Default
To prevent potential data loss caused by a known issue impacting Sonatype Nexus Repository 3.83.0 and later, the Repair - Execute Data Repair Plan task is now disabled by default starting in version 3.88.0.
Attempting to run this task in 3.88.0 will result in a failure and an error in the logs. The task remains visible in the UI, and any existing instances of this task will not be removed. However, execution is blocked by default.
While it is possible to manually re-enable this task by setting the nexus.reconcile.task.enabled property to true, it is important that you not do so until you are using a release that restores support.
Bug Fixes
This release delivers a wide range of fixes and improvements focused on stability, accuracy, and operational reliability. For better readability, we’ve organized these improvements into logical sections below.
Note
Common Vulnerabilities and Exposures Fix
Sonatype Nexus Repository 3.88.0 fixes a reflected cross-site scripting (XSS) vulnerability (CVE-2026-0601) that impacts Sonatype Nexus Repository versions 3.82.0 through 3.87.1.
The vulnerability allows unauthenticated attackers to execute arbitrary JavaScript in a victim’s browser, which could lead to privilege escalation or unauthorized configuration changes.
