安全公告和 CVE
Rancher 致力于向社区披露我们产品的安全问题。我们会针对已解决的问题发布安全公告和 CVE（Common Vulnerabilities and Exposures，通用漏洞披露）。Rancher GitHub 上的安全页面也会发布新的安全公告。
| ID | 描述 | 日期 | 解决 |
|---|---|---|---|
A vulnerability was found where users with permission to create a service in the Kubernetes cluster where Rancher is deployed can take over the Rancher UI, display their own UI, and gather sensitive information. This is only possible when the setting |

A vulnerability has been identified within Rancher where a Restricted Administrator can change the password of Administrators and take over their accounts. A Restricted Administrator should not be allowed to change the password of more privileged users unless it contains the Manage Users permissions. A new validation has been added to block a user from editing or deleting another user with more permissions than themselves. Rancher deployments where the Restricted Administrator role is not being used are not affected by this CVE. |

A vulnerability in Rancher has been discovered, leading to a local user impersonation through SAML Authentication on first login. The issue occurs when a SAML authentication provider (AP) is configured (e.g. Keycloak). A newly created AP user can impersonate any user on Rancher by manipulating cookie values during their initial login to Rancher. This vulnerability could also be exploited if a Rancher user (present on the AP) is removed, either manually or automatically via the User Retention feature with delete-inactive-user-after |

An unauthenticated stack overflow crash, leading to a denial of service (DoS), was identified in Rancher’s This vulnerability affects those using external authentication providers as well as Rancher’s local authentication. |

||
A vulnerability has been identified within Rancher where it is possible for an unauthenticated user to list all CLI authentication tokens and delete them before the CLI is able to get the token value. This effectively prevents users from logging in via the CLI when using rancher token as the execution command (instead of the token directly being in the kubeconfig). Note that this token is not the kubeconfig token and if an attacker is able to intercept it they can’t use it to impersonate a real user since it is encrypted. |

||
A high severity vulnerability was identified within the Rancher UI that allows a malicious actor to perform a Stored XSS attack through the cluster description field. |
15 Jan 2025 |
||
A medium severity vulnerability was discovered within Rancher Manager whereby applications installed via Rancher Manager Apps Catalog store their Helm values directly into the Apps Custom Resource Definition, resulting in any users with GET access to it to be able to read any sensitive information that are contained within the Apps’ values. Additionally, the same information leaks into auditing logs when the audit level is set to equal or above 2. Rancher v2.7 is vulnerable and hasn’t received the fix. |

A critical severity vulnerability was discovered in the way that Rancher stores vSphere’s CPI (Cloud Provider Interface) and CSI (Container Storage Interface) credentials used to deploy clusters through the vSphere cloud provider. This issue leads to the vSphere CPI and CSI passwords being stored in a plaintext object inside Rancher. This vulnerability is only applicable to users that deploy clusters in vSphere environments. Rancher v2.7 is vulnerable and hasn’t received the fix. |
24 Oct 2024 |
||
A high severity vulnerability was discovered in Rancher’s agents that under very specific circumstances allows a malicious actor to take over existing Rancher nodes. The attacker needs to have control of an expired domain or execute a DNS spoofing/hijacking attack against the domain in order to exploit this vulnerability. The targeted domain is the one used as the Rancher URL (the |

An issue was discovered in Rancher versions up to and including 2.7.13 and 2.8.4, where Rancher did not have a user retention process for when external authentication providers are used, that could be configured to run periodically and disable and/or delete inactive users. The new user retention process added in Rancher v2.8.5 and Rancher v2.7.14 is disabled by default. If enabled, a user becomes subject to the retention process if they don’t log in for a configurable period of time. It’s possible to set overrides for user accounts that are primarily intended for programmatic access (e.g. CI, scripts, etc.) so that they don’t become subject to the retention process for a longer period of time or at all. |
17 Jun 2024 |
||
An issue was discovered in Rancher versions up to and including 2.7.13 and 2.8.4, in which supported RKE versions store credentials inside a ConfigMap that can be accessible by non-administrative users in Rancher. This vulnerability only affects an RKE-provisioned cluster. |
