{"schemaVersion":3,"id":"CVE-2026-88808","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability has been identified within Rancher Manager where the Fleet agent wrote resources to downstream clusters using its own cluster-admin credentials instead of the ServiceAccount pinned to the deployment. It affects multi-tenancy environments where different tenants share the same downstream clusters, for example different privileged or untrusted teams inside the same organization. This could lead to overwritten configuration files.\n\nThis issue affected SUSE Rancher Fleet 0.16 before 0.16.2, 0.15 before 0.15.7, and 0.14 before 0.14.11.","dates":{"published":"2026-09-28T15:36:13.506Z","modified":"2026-09-29T03:55:24.347Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00278,"percentile":0.19042,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-09-29T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00278,"percentile":0.19042}],"last30":[{"date":"2026-09-29T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00278,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00278,"percentile":0.19042}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-250","name":"Execution
