The result is passed to `PreserveUnauthorizedPrivilegedPermissionsAction`, which selectively restores only the `superuser` key (when the editor is not a superuser) and the `admin` key (when the editor is neither admin nor superuser). All other permissions — including the `admin` flag itself when the editing user is an admin — are discarded and `$user->permissions` is overwritten with the sparse result.\n\nThe `canEditAuthFields` gate permits admins to update other non-superuser accounts (including other admins). When an admin sends a `PUT /users/{id}` request for another admin without including the `permission` field, the target's `admin` flag and all granular permissions are permanently destroyed. The target loses administrative access entirely with no error, warning, or out-of-band notification.\n\nA secondary, lower-impact path exists for non-admin users holding the `users.edit` permission: they may target regular (non-admin, non-superuser) accounts and wipe all granular permissions in the same way.\n\n### Patches\nPatched in https://github.com/grokability/snipe-it/commit/1cff2d67aabd00ee51d864c1d7fb717494c1d6ad\n\n## Affected packages\n\n- `snipe/snipe-it < 8.6.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `snipe/snipe-it 8.6.0`","depth":"twilight","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
