PatchTheCVECVE-2026-75035: A flaw was found in Rancher Manager
CVE-2026-75035 is a high-severity flaw (CVSS 7.7) affecting rancher. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A flaw was found in Rancher Manager. When a non-administrative caller supplied a label selector naming a different user, the ext.cattle.io/v1 Token store dropped its internal owner filter instead of returning an empty result. Any authenticated user could therefore list and watch every other user's tokens, disclosing token metadata and the stored salted hash of the bearer token. This issue affects Rancher: before 2.15.1.
Why this priority
- High severity
A fixed release or distro patch exists.
