{"id":"CVE-2026-48826","published":"2026-09-21T18:17:08.073","lastModified":"2026-09-23T18:26:49.087","description":"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.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","cwes":["CWE-269","CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/sysadminsmedia/homebox/commit/ed3216a80998dfd81d4418700696244144883160","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/releases/tag/v0.26.0","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/security/advisories/GHSA-559j-7w3w-4fr7","tags":[]}],"exploitRefs":[{"url":"https://github.com/sysadminsmedia/homebox/commit/ed3216a80998dfd81d4418700696244144883160","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/releases/tag/v0.26.0","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/security/advisories/GHSA-559j-7w3w-4fr7","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows a user to delete another group's inventory by exploiting the global owner role, leading to data loss.","exploitability":"Exploitation is moderately hard as it requires the attacker to be a member of another group and manipulate the X-Tenant header.
