Sonatype Nexus Repository 3 allows a user account that holds the edit permission on a hosted R repository to store script content in the metadata of an uploaded R package. The script runs in the browser of a user who opens the details of that package in the Browse user interface, with the permissions of the viewing user. In this description, a user account means an account that has supplied valid credentials. The anonymous user, if enabled, is also a user account and can hold this permission if an administrator grants it.

Oct 15, 2026A missing authorization check in Nexus Repository 3's NuGet Components API upload path allows an account holding only repository read and browse privileges to uCVE-2026-97665 · Other software · Sonatype · reported by 103e4ec9-0a87-450b-af77-479448ddef11High 7.1
A missing authorization check in Nexus Repository 3's NuGet Components API upload path allows an account holding only repository read and browse privileges to upload and persist NuGet symbol packages (.snupkg) to a hosted repository, bypassing the write-permission check enforced for ordinary package uploads. Exploitation requires a hosted NuGet repository with Symbol Server enabled. If anonymous access is enabled, the built-in anonymous user holds read and browse privileges across all repositories by default, so this precondition can also be met without an authenticated account.

Sep 2, 2026A vulnerability was identified in Sonatype Nexus Repository 3 in which two blobstore group management REST API endpoints did not correctly enforce the intended CVE-2026-77125 · Other software · Sonatype · reported by 103e4ec9-0a87-450b-af77-479448ddef11High 7.1
A vulnerability was identified in Sonatype Nexus Repository 3 in which two blobstore group management REST API endpoints did not correctly enforce the intended authorization check. A user granted only the nexus:blobstores:create permission could invoke these endpoints to convert an existing blobstore into a group blobstore, an action that should require the nexus:blobstores:update permission instead. This could result in unauthorized modification of blobstore configuration without administrator approval. The nexus:blobstores:create permission is a named permission that must be explicitly granted by an administrator; it is not held by default.

In affected versions of Nexus Repository 3, the script execution endpoint (POST /service/rest/v1/script/{name}/run) did not verify whether script execution had been administratively disabled. An account holding script-execution permission could continue to run previously-created scripts even after an administrator set nexus.scripts.allowCreation=false, undermining the expectation that this setting fully blocks script execution.

An authorization flaw in the REST API repository details endpoint (GET /service/rest/v1/repositories/{repositoryName}) in Sonatype Nexus Repository 3 allowed an account holding read or browse permission on a group repository to retrieve metadata for member repositories on which it held no direct permission, by requesting the endpoint directly for the member repository name. For proxy repositories, the disclosed metadata includes the configured remote URL, which may reveal internal upstream hostnames. This includes the anonymous user if it has been granted this permission; whether the anonymous user holds this permission depends on the role and permission configuration of the specific installation.

A user account with permission to deploy artifacts to a hosted Maven repository could upload a POM file containing an oversized metadata field. This causes future attempts to list or browse that repository's components to permanently fail until an administrator repairs the underlying data. Only the targeted repository is affected; other repositories and overall server health remain unaffected.

Nexus Repository 3 did not sufficiently restrict which HikariCP connection-pool properties could be set through the DataStore configuration API. A user holding the nx-datastores-update permission could set the connectionInitSql property to execute arbitrary SQL against the configured database on every new connection. On the default H2 database backend, this could be leveraged to achieve remote code execution as the Nexus process user.

Aug 7, 2026Sonatype Nexus Repository 3 did not immediately terminate a user's active login session or revoke their cached permissions when that user's account was deleted,CVE-2026-17600 · Other software · Sonatype · reported by 103e4ec9-0a87-450b-af77-479448ddef11High 8.7
Sonatype Nexus Repository 3 did not immediately terminate a user's active login session or revoke their cached permissions when that user's account was deleted, deactivated, or had its password changed. A user whose account was already logged in at the time of one of these actions could continue using their existing session to interact with the repository as though the account were still active, until that session independently expired. Depending on the permissions previously held, this could allow continued unauthorized access to read, modify, or delete repository content after access was intended to be revoked.

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.

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 did not fully sandbox JEXL expressions used in Content Selectors. An account holding the nexus:selectors:create permission could construct an expression that read Java object properties not intended to be exposed to the expression engine, disclosing internal JVM class metadata such as class and classloader names. This issue does not permit method invocation, object construction, or arbitrary code execution. This has been fixed by restricting property access in the JEXL sandbox to the intended data types.

Nexus Repository 3 CE/Pro versions 3.0.0 through 3.94.x contain an incorrect authorization vulnerability (CWE-863) in the repository-creation user interface. An individual user account holding a delegated repository-admin privilege scoped to a specific repository format could create a repository of a different, unauthorized format, because authorization was checked against one request field while a separate, attacker-controlled field determined the repository format actually created. This does not affect the anonymous user, which cannot hold this privilege by default. Fixed in version 3.95.0.

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, and in some cases a persistent authentication lockout that was not visible through the administrative UI.
