CVE-2022-43760Network attack vector

Administrator impersonation via stored UI script injection

Published Jun 1, 2023 · Updated Jan 9, 2025

Stored XSS in the Rancher UI 2.6.0 through 2.6.12 and 2.7.0 through 2.7.3 allows remote authenticated users to execute scripts. The Projects/Namespaces and Auth Provider views render attacker-controlled content without neutralizing script-related HTML tags. A user with write access to either area must convince an administrator to open the affected page, after which the script runs with the administrator's browser privileges and can steal sensitive information or alter content.
