Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.35% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Jenkins Project Jenkins and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

CVE-2026-27100 · CSAF 2.0 · revision 3 · finalRed Hat Product Securityorg.jenkins-ci.main/jenkins-core: Jenkins: Information disclosure via unauthorized access to build parameters
1 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • jenkins.src as a component of OpenShift Developer Tools and Services
Summary
A flaw was found in Jenkins. An attacker with Item/Build and Item/Configure permissions can exploit this vulnerability by submitting Run Parameter values that refer to builds they do not have authorization to access. This allows the attacker to obtain sensitive information, including the existence of jobs, the existence of builds, and the display names of specific builds. This is an information disclosure vulnerability.
Remediation
It is recommended that existing users of Red Hat OpenShift Developer Tools - OpenShift Jenkins 4.12 upgrade to the latest. This update includes a newer OpenShift client (oc) version bundled in the image. If your Jenkins pipelines require a specific oc version, configure it explicitly using the Jenkins pipeline tools directive.

01

What, why and how

Jenkins 2.550 and earlier, LTS 2.541.1 and earlier accepts Run Parameter values that refer to builds the user submitting the build does not have access to, allowing attackers with Item/Build and Item/Configure permission to obtain information about the existence of jobs, the existence of builds, and if a specified build exists, its display name.

What

Jenkins 2.550 and earlier, LTS 2.541.1 and earlier accepts Run Parameter values that refer to builds the user submitting the build does not have access to, allowing attackers with Item/Build and Item/Configure permission to obtain information about the existence of jobs, the existence of builds, and if a specified build exists, its display name.

Why

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
