CVE-2026-21725

*** Pendiente de traducción *** A time-of-create-to-time-of-use (TOCTOU) vulnerability lets recently deleted-then-recreated data sources be re-deleted without permission to do so.<br /> <br /> This requires several very stringent conditions to be met:<br /> <br /> - The attacker must have admin access to the specific datasource prior to its first deletion.<br /> - Upon deletion, all steps within the attack must happen within the next 30 seconds and on the same pod of Grafana.<br /> - The attacker must delete the datasource, then someone must recreate it.<br /> - The new datasource must not have the attacker as an admin.<br /> - The new datasource must have the same UID as the prior datasource. These are randomised by default.<br /> - The datasource can now be re-deleted by the attacker.<br /> - Once 30 seconds are up, the attack is spent and cannot be repeated.<br /> - No datasource with any other UID can be attacked.
