Summary
keystone vulnerabilities
Details

Grzegorz Grasza discovered that OpenStack Keystone did not consistently enforce restrictions for delegated authentication tokens. An authenticated attacker could possibly use this issue to create credentials or delegations that outlasted the delegated token. (CVE-2026-80182)

It was discovered that OpenStack Keystone incorrectly handled role assignment queries under certain circumstances. An authenticated attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-80183)

Tim Shephard discovered that OpenStack Keystone did not properly restrict reauthentication using delegated tokens. An authenticated attacker could possibly use this issue to escape their intended project scope and obtain unauthorized access. (CVE-2026-80184)
