| [CVE-2026-44949](https://github.com/rancher/webhook/security/advisories/GHSA-h83p-cq95-vph4) | Fixed a security vulnerability in rancher-webhook where the FleetWorkspace mutating admission webhook performed side effects without authenticating requests, allowing a pod inside the cluster to create arbitrary namespaces and inject RBAC bindings. | 29 June 2026 | Rancher [v2.14.3](https://github.com/rancher/rancher/releases/tag/v2.14.3), Rancher [v2.13.7](https://github.com/rancher/rancher/releases/tag/v2.13.7), Rancher [v2.12.11](https://github.com/rancher/rancher/releases/tag/v2.12.11) and Rancher [v2.11.15](https://github.com/rancher/rancher/releases/tag/v2.11.15) |
| [CVE-2026-44947](https://github.com/rancher/rancher/security/advisories/GHSA-c4rp-wgqc-mfhc) | Fixed a security vulnerability in Rancher's legacy PRTB reconciler where removing the `updatepsa` permission from a RoleTemplate did not clean up stale PSA ClusterRole and ClusterRoleBinding resources, allowing affected users to retain unauthorized Pod Security Admission access indefinitely. | 29 June 2026 | Rancher [v2.14.3](https://github.com/rancher/rancher/releases/tag/v2.14.3) and Rancher [v2.13.7](https://github.com/rancher/rancher/releases/tag/v2.13.7) |
| [CVE-2026-44946](https://github.com/rancher/rancher/security/advisories/GHSA-c5jm-xcmq-9j95) | Fixed a security vulnerability in Rancher's SAML authentication handler where a valid signed SAML response could be replayed by an attacker who had also captured the victim's pre-authentication SAML state cookie, allowing the attacker to create a separate authenticated session with the victim's permissions. All SAML providers (Okta, Ping, ADFS, Keycloak, Shibboleth) were affected. | 29 June 2026 | Rancher [v2.14.3](https://github.com/rancher/rancher/releases/tag/v2.14.3), Rancher [v2.13.7](https://github.com/rancher/rancher/releases/tag/v2.13.7), Rancher [v2.12.11](https://github.com/rancher/rancher/releases/tag/v2.12.11) and Rancher [v2.11.15](https://github.com/rancher/rancher/releases/tag/v2.11.15) |
| [CVE-2026-41053](https://github.com/rancher/rancher/security/advisories/GHSA-4j6x-2764-m8gh) | Fixed a security vulnerability in the GitHub App authentication provider where users incorrectly inherited permissions from all teams within their GitHub organization, rather than only the specific teams to which they belonged. Upon upgrading, Rancher automatically triggers a mandatory refresh of all affected user `principals` to remove these incorrectly assigned team memberships and restore proper access. | 27 May 2026 | Rancher [v2.14.2](https://github.com/rancher/rancher/releases/tag/v2.14.2), Rancher [v2.13.6](https://github.com/rancher/rancher/releases/tag/v2.13.6) |
| [CVE-2026-41052](https://github.com/rancher/rancher/security/advisories/GHSA-vx8h-4prv-g744) | Updated the permissions of the built-in `project-owner` role to no longer include the `updatepsa` verb. This prevents users with this role from bypassing restricted PSA policies or deploying privileged workloads within their projects. If your organization requires users to retain this capability, administrators must create a custom project role that explicitly grants the `updatepsa` verb for the project resource. | 27 May 2026 | Rancher [v2.14.2](https://github.com/rancher/rancher/releases/tag/v2.14.2), Rancher [v2.13.6](https://github.com/rancher/rancher/releases/tag/v2.13.6), [v2.12.10](https://github.com/rancher/rancher/releases/tag/v2.12.10) |
| [CVE-2026-44939](https://github.com/rancher/rancher/security/advisories/GHSA-mhc6-2gfq-xx62) | Rancher now validates the `authImage` parameter in cluster import manifests to prevent YAML injection attacks. | 27 May 2026 | Rancher [v2.14.2](https://github.com/rancher/rancher/releases/tag/v2.14.2), Rancher [v2.13.6](https://github.com/rancher/rancher/releases/tag/v2.13.6), [v2.12.10](https://github.com/rancher/rancher/releases/tag/v2.12.10), [v2.11.14](https://github.com/rancher/rancher/releases/tag/v2.11.14), and [v2.10.12](https://github.com/rancher/rancher/releases/tag/v2.10.12) |
