PR:L because exploitation requires GitRepo repository write access; C:L reflects limited templating-context metadata and DNS enumeration only; no integrity or availability impact confirmed by advisory.

DescriptionCVE.org

A security vulnerability was discovered in Fleet's Helm template preprocessing where templates evaluated by the Fleet controller could reach network resources outside the management cluster. A user who can supply bundle content to a repository referenced by a GitRepo resource can cause the Fleet controller to:

  • Disclose cluster metadata available to the templating context.
  • Reveal information about hosts reachable from the controller's network position.

Because the disclosure channel is name resolution, it may remain effective in environments where outbound traffic is otherwise restricted. The disclosed information is limited to values exposed to the Fleet templating context and to name resolution results. Integrity and availability of managed clusters are not affected.

This issue affects Fleet: from 0.12.0 before 0.12.19, from 0.13.0 before 0.13.15, from 0.14.0 before 0.14.10, from 0.15.0 before 0.15.6, and from 0.16.0 before 0.16.1.

AnalysisAI

Fleet controller's Helm template preprocessing exposes cluster metadata and internal DNS topology to any user with write access to a GitRepo-tracked repository, via a server-side request forgery path that abuses name resolution. Affected releases span all active branches from 0.12.0 through 0.16.0, with patched builds released across each branch. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the attacker hold write access to a Git repository referenced by a Fleet GitRepo resource - specifically, the ability to commit Helm bundle content that the Fleet controller will process during reconciliation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.3 (Medium) is appropriate and well-calibrated: PR:L correctly captures that exploitation requires existing GitRepo repository write access rather than unauthenticated network reachability, and the VC:L/VI:N/VA:N vector reflects a bounded information-disclosure outcome with no path to cluster compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade Fleet to the patched release corresponding to the deployed branch: 0.12.19, 0.13.15, 0.14.10, 0.15.6, or 0.16.1, per the Rancher security advisory at https://github.com/rancher/fleet/security/advisories/GHSA-x9m6-xcjr-hpjp. … Detailed patch versions, workarounds, and compensating controls in full report.
