- ">=11.6.11 >=12.0.9 >=12.1.6 >=12.2.4"
--- A cross-tenant isolation vulnerability was found in Grafana’s Correlations feature affecting legacy correlation records. Due to a backward compatibility condition allowing org_id = 0 records to be returned across organizations, a user with datasource management privileges could read and permanently delete legacy correlation data belonging to another organization. This issue affects correlations created prior to Grafana 10.2 and is fixed in >=11.6.11, >=12.0.9, >=12.1.6, and >=12.2.4.
Thanks to Gyu-hyeok Lee (g2h) for reporting this vulnerability.
