{"id":"CVE-2026-108854","summary":"Wanwu before 0.6.3 IDOR AppKey Deletion via DELETE /v1/appspace/app/key","details":"Wanwu before 0.6.3 contains an insecure direct object reference vulnerability that allows any authenticated enabled user to delete other users' legacy AppKeys by supplying a numeric apiId. Attackers can iterate sequential key IDs against DELETE /v1/appspace/app/key to revoke AppKeys across organizations, breaking MCP and OpenAPI clients until owners issue new keys.","modified":"2026-10-13T02:46:20.260285058Z","published":"2026-10-11T13:26:03.304Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108854.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-639"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108854.json"},{"type":"ADVISORY","url":"https://github.com/UnicomAI/wanwu/releases/tag/v0.6.3"},{"type":"ADVISORY","url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/unicomai-wanwu-appkey-delete-id-bola"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-108854"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/wanwu-before-0.6.3-idor-appkey-deletion-via-delete-v1-appspace-app-key"},{"type":"FIX","url":"https://github.com/UnicomAI/wanwu/commit/13d0b225ec237d5a0b44730b2331efadaeb462a2"},{"type":"PACKAGE","url":"https://github.com/UnicomAI/wanwu"},{"type":"ARTICLE","url":"https://github.com/UnicomAI/wanwu/blob/v0.6.2/internal/app-service/client/orm/app_key.go#L26-L31"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/unicomai/wanwu","events":[{"introduced":"0"},{"fixed":"88dd0894243fccbc1745eb04d2c5dc61ad1af0b6"},{"fixed":"13d0b225ec237d5a0b44730b2331efadaeb462a2"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"0.6.3"}]}}],"versions":["v0.6.2","v0.6.1","v0.6.0","v0.5.10","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.5","v0.4.3","v0.4.1","v0.4.2","v0.4.0","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.9","v0.2.8","v0.2.7","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.8","v0.1.7","v0.1.5","v0.1.3-dc97f77","v0.1.3","v0.1.2","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-108854.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
