CVE-2026-17593 Alta · 7.2 CWE-470 07/08/2026

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

CVE-2026-7494 Média · 5.0 CWE-918 14/07/2026

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.

CVE-2026-10748 Alta · 7.2 CWE-502 16/06/2026

Nexus Repository 3 - Remote Code Execution via License Deserialization

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.

CVE-2026-7308 Média · 5.4 CWE-79 11/05/2026

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.

CVE-2026-3048 Baixa · 3.8 CWE-502 11/05/2026

Nexus Repository 3 - Improper LDAP Referral Handling

An authenticated administrator who configures or tests LDAP connectivity in Sonatype Nexus Repository Manager versions 3.0.0 through 3.91.1 may be able to initiate unintended server-side connections when interacting with a malicious LDAP server.

CVE-2026-5189 Crítica · 9.8 CWE-798 15/04/2026

Nexus Repository 3 - Hardcoded Credential in Internal Database Component

CWE-798: Use of Hard-coded Credentials in Sonatype Nexus Repository Manager versions 3.0.0 through 3.70.5 allows an unauthenticated attacker with network access to gain unauthorized read/write access to the internal database and execute arbitrary OS commands as the Nexus process user. Exploitation requires the non-default nexus.orient.binaryListenerEnabled=true configuration to be enabled.

CVE-2026-3438 Média · 6.1 CWE-79 08/04/2026

Nexus Repository 3 - Reflected Cross-Site Scripting (XSS) in ?describe Pages

A reflected cross-site scripting vulnerability exists in Sonatype Nexus Repository versions 3.0.0 through 3.90.2 that allows unauthenticated remote attackers to execute arbitrary JavaScript in a victim's browser through a specially crafted URL. Exploitation requires user interaction.

CVE-2026-3199 Alta · 8.8 CWE-502 08/04/2026

Nexus Repository 3 - Authenticated Remote Code Execution via Task Property Injection

A vulnerability in the task management component of Sonatype Nexus Repository versions 3.22.1 through 3.90.2 allows an authenticated attacker with task creation permissions to execute arbitrary code, bypassing the nexus.scripts.allowCreation security control.

CVE-2026-0600 Média · 6.2 CWE-918 14/01/2026

Nexus Repository 3 - Server-Side Request Forgery in Proxy Repository Configuration

Server-Side Request Forgery (SSRF) vulnerability in Sonatype Nexus Repository 3 versions 3.0.0 and later allows authenticated administrators to configure proxy repositories with URLs that can access unintended network destinations, potentially including cloud metadata services and internal network resources. A workaround configuration is available starting in version 3.88.0, but the product remains vulnerable by default.

CVE-2026-0601 Média · 5.1 CWE-79 14/01/2026

Nexus Repository 3 - Cross-Site Scripting

A reflected cross-site scripting vulnerability exists in Nexus Repository 3 that allows unauthenticated attackers to execute arbitrary JavaScript in a victim's browser through a specially crafted request requiring user interaction.

CVE-2025-13488 Média · 5.1 CWE-79 04/12/2025

Nexus Repository 3 - Stored Cross-Site Scripting (XSS)

Due to a regression introduced in version 3.83.0, a security header is no longer applied to certain user-uploaded content served from repositories. This may allow an authenticated attacker with repository upload privileges to exploit a stored cross-site scripting (XSS) vulnerability with user context.
