CVE-2026-84652 (GCVE-0-2026-84652)

Vulnerability from nvd – Published: 2026-09-02 15:40 – Updated: 2026-09-03 15:22

Summary

In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, Jenkins does not rotate the session when a user is authenticated via the "remember me" cookie, allowing attackers able to serve content on the same site as Jenkins to set a known session cookie in the victim's browser, which after the victim authenticates via the "remember me" cookie, grants the attacker access to Jenkins as that user.

Severity

7.3 (High)

CVE-2026-84651 (GCVE-0-2026-84651)

Vulnerability from nvd – Published: 2026-09-02 15:40 – Updated: 2026-09-02 17:23

Summary

In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the REST API and CLI endpoints for updating agent configuration do not prevent a submitted configuration from overwriting a different agent by specifying that agent's name in the submitted XML document, allowing attackers with Agent/Configure permission on one agent to take over a different agent, gaining control of its configuration and obtaining access to its inbound agent secret and environment variables.

Severity

6.3 (Medium)

Summary

In Stapler 1839.ved17667b_a_eb_5 through 2107.v8dfcb_e8ed317 (both inclusive), except 2088.2093.vd7c3e58008a_6, included in Jenkins 2.447 through 2.579 (both inclusive), LTS 2.452.1 through 2.568.2 (both inclusive), an HTTP endpoint serving dynamically generated JavaScript resources embeds the user's cross-site request forgery (CSRF) token (crumb) as a string literal, allowing attackers with control over a page hosted on the same site as Jenkins to obtain a valid crumb for the targeted user's session and perform actions on their behalf.

CVE-2026-84645 (GCVE-0-2026-84645)

Vulnerability from nvd – Published: 2026-09-02 15:40 – Updated: 2026-09-03 03:56

Summary

In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, objects of types marked as storing their configuration in independent top-level configuration files in Jenkins (such as the global configuration and jobs) can appear as nested field values in user-submitted `config.xml` documents and subsequently handle HTTP requests via Stapler, resulting in remote code execution.

Severity

8.8 (High)

CVE-2026-84652 (GCVE-0-2026-84652)

Vulnerability from cvelistv5 – Published: 2026-09-02 15:40 – Updated: 2026-09-03 15:22

Summary

In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, Jenkins does not rotate the session when a user is authenticated via the "remember me" cookie, allowing attackers able to serve content on the same site as Jenkins to set a known session cookie in the victim's browser, which after the victim authenticates via the "remember me" cookie, grants the attacker access to Jenkins as that user.

Severity

7.3 (High)

CVE-2026-84651 (GCVE-0-2026-84651)

Vulnerability from cvelistv5 – Published: 2026-09-02 15:40 – Updated: 2026-09-02 17:23

Summary

In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the REST API and CLI endpoints for updating agent configuration do not prevent a submitted configuration from overwriting a different agent by specifying that agent's name in the submitted XML document, allowing attackers with Agent/Configure permission on one agent to take over a different agent, gaining control of its configuration and obtaining access to its inbound agent secret and environment variables.

CVE-2026-84645 (GCVE-0-2026-84645)

Vulnerability from cvelistv5 – Published: 2026-09-02 15:40 – Updated: 2026-09-03 03:56

Summary

In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, objects of types marked as storing their configuration in independent top-level configuration files in Jenkins (such as the global configuration and jobs) can appear as nested field values in user-submitted `config.xml` documents and subsequently handle HTTP requests via Stapler, resulting in remote code execution.

Severity
