{"id":"CVE-2026-48826","published":"2026-09-21T18:17:08.073","lastModified":"2026-09-21T21:17:03.483","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 privilege through the X-Tenant header, leading to irreversible data loss.","exploitability":"Exploitation requires access to the X-Tenant header and knowledge of another group’s ID, making it moderately difficult but feasible for an attacker with sufficient information.","blast_radius":"If exploited, this can result in significant data loss across multiple groups, impacting users who rely on the system for inventory management.","remediation":"Update to version 0.26.0 or later to apply the necessary authorization fix.","tags":["auth-bypass","data-loss","web"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:08:32.712Z"}}
