- Severity: medium (CVSS 6.5 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known

- Weakness: CWE-639
Description
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.
Affected products
- SUSE Rancher: before 2.15.1 — fixed in 2.15.1
How to fix
Upgrade to a fixed version: SUSE Rancher 2.15.1. Check the vendor advisory for mitigations.
