{"id":"CVE-2026-48826","summary":"HomeBox: Cross-Group Inventory Wipe in Homebox via Global Owner Role and X-Tenant Header Switching","details":"HomeBox is a home inventory and organization system. Prior to 0.26.0, HandleWipeInventory in backend/app/api/handlers/v1/v1_ctrl_actions.go authorizes POST /v1/actions/wipe-inventory through the global ctx.User.IsOwner value instead of the caller's role in the active group, while the active group is selected through the X-Tenant request header. Because every self-registered user who creates a group receives the global owner value, a user who is also a member of another group can select that group with X-Tenant and permanently delete its complete inventory, which is not recoverable without external backups. This issue is fixed in version 0.26.0.","aliases":["GHSA-559j-7w3w-4fr7"],"modified":"2026-09-23T03:45:33.010636724Z","published":"2026-09-21T17:43:43.510Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48826.json"},"references":[{"type":"WEB","url":"https://github.com/sysadminsmedia/homebox/releases/tag/v0.26.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48826.json"},{"type":"ADVISORY","url":"https://github.com/sysadminsmedia/homebox/security/advisories/GHSA-559j-7w3w-4fr7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48826"},{"type":"FIX","url":"https://github.com/sysadminsmedia/homebox/commit/ed3216a80998dfd81d4418700696244144883160"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sysadminsmedia/homebox","events":[{"introduced":"0"},{"fixed":"ed3216a80998dfd81d4418700696244144883160"},{"fixed":"c0bcd3b4682fce0fb512cb191ea754d725e416ee"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"0.26.0"}]}}],"versions":["v0.26.0-rc.1","v0.25.0","v0.25.0-rc.1","v0.24.2","v0.24.1","v0.24.0","v0.24.0-rc.1","v0.23.1","v0.23.0","v0.23.0-rc.1","v0.22.3","v0.22.2","v0.22.1","v0.22.0-rc.1","v0.21.0","v0.20.2","v0.20.1","v0.19.0","v0.18.0","v0.17.2","v0.17.1","v0.17.0","v0.16.0","v0.15.2","v0.15.1","v0.15.0","v0.14.2","v0.14.1","v0.14.0","v0.13.0","v0.12.1","v0.12.0","v0.11.1","v0.11.0","v0.9.2","v0.9.1","v0.9.0","v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.1","v0.5.0","v0.4.0","v0.3.1","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48826.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"}]}
