{"id":"GHSA-j5g3-42wp-gqm3","summary":"Snipe-IT has an Improper Privilege Management issue","details":"## Impact\n\nThe `update()` method in `UsersController` passes the `permission` request field unconditionally to `NormalizePermissionsPayloadAction`, which returns an empty array when the field is absent. 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-\u003epermissions` 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","aliases":["CVE-2026-55843"],"modified":"2026-08-28T22:45:06.777701927Z","published":"2026-08-28T22:37:24Z","database_specific":{"nvd_published_at":"2026-07-10T19:17:26Z","cwe_ids":["CWE-269"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-08-28T22:37:24Z"},"references":[{"type":"WEB","url":"https://github.com/grokability/snipe-it/security/advisories/GHSA-j5g3-42wp-gqm3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55843"},{"type":"WEB","url":"https://github.com/grokability/snipe-it/commit/1cff2d67aabd00ee51d864c1d7fb717494c1d6ad"},{"type":"PACKAGE","url":"https://github.com/grokability/snipe-it"},{"type":"WEB","url":"https://github.com/grokability/snipe-it/releases/tag/v8.6.0"}],"affected":[{"package":{"name":"snipe/snipe-it","ecosystem":"Packagist","purl":"pkg:composer/snipe/snipe-it"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.6.0"}]}],"versions":["3.2.0","v0.1.0","v0.1.1","v0.1.2","v0.2.0","v0.3.0-alpha","v0.3.10-alpha","v0.3.11-alpha","v0.3.7-alpha","v0.3.8-alpha","v0.3.9-alpha","v1.0","v1.1","v1.2.0","v1.2.1","v1.2.10","v1.2.11","v1.2.2","v1.2.3","v1.2.3-beta","v1.2.4","v1.2.4-beta","v1.2.5","v1.2.6","v1.2.6-beta","v1.2.6.1","v1.2.7","v1.2.7-beta","v1.2.8","v1.2.9","v2.0","v2.0-RC-1","v2.0-beta","v2.0.1","v2.0.2","v2.0.3","v2.0.4","v2.0.5","v2.0.6","v2.1.0","v2.1.1","v2.1.2","v3.0","v3.0-alpha","v3.0-alpha2","v3.0-beta.1","v3.0-beta.2","v3.0-beta.3","v3.0.0-beta","v3.1.0","v3.3.0","v3.3.0-beta","v3.4","v3.4.0-alpha","v3.4.0-beta","v3.5.0","v3.5.0-beta","v3.5.0-beta2","v3.5.1","v3.5.2","v3.6.0","v3.6.1","v3.6.2","v3.6.3","v3.6.4","v3.6.5","v3.6.6","v4-beta3","v4-beta4","v4.0","v4.0-alpha","v4.0-alpha-2","v4.0-beta","v4.0-beta2","v4.0-beta5","v4.0-beta6","v4.0.1","v4.0.10","v4.0.11","v4.0.12","v4.0.13","v4.0.14","v4.0.15","v4.0.2","v4.0.3","v4.0.4","v4.0.5","v4.0.6","v4.0.7","v4.0.8","v4.0.9","v4.1.0","v4.1.0-beta","v4.1.0-beta2","v4.1.1","v4.1.10","v4.1.11","v4.1.12","v4.1.13","v4.1.14","v4.1.2","v4.1.3","v4.1.4","v4.1.5","v4.1.6","v4.1.7","v4.1.8","v4.1.9","v4.2.0","v4.3.0","v4.4.0","v4.4.1","v4.5.0","v4.6.0","v4.6.1","v4.6.10","v4.6.11","v4.6.12","v4.6.13","v4.6.14","v4.6.15","v4.6.16","v4.6.17","v4.6.18","v4.6.2","v4.6.3","v4.6.4","v4.6.5","v4.6.6","v4.6.7","v4.6.8","v4.6.9","v4.7.0","v4.7.1","v4.7.2","v4.7.3","v4.7.4","v4.7.5","v4.7.6","v4.7.7","v4.7.8","v4.8.0","v4.9.0","v4.9.1","v4.9.2","v4.9.3","v4.9.4","v4.9.5","v5.0.0","v5.0.0-beta-1.0","v5.0.0-beta-1.1","v5.0.0-beta-2","v5.0.0-beta-3.0","v5.0.0-beta-4","v5.0.0-beta-5","v5.0.1","v5.0.10","v5.0.11","v5.0.12","v5.0.2","v5.0.3","v5.0.4","v5.0.5","v5.0.6","v5.0.7","v5.0.8","v5.0.9","v5.1.0","v5.1.1","v5.1.2","v5.1.3","v5.1.4","v5.1.5","v5.1.6","v5.1.7","v5.1.8","v5.2.0","v5.3.0","v5.3.1","v5.3.10","v5.3.2","v5.3.3","v5.3.4","v5.3.5","v5.3.6","v5.3.7","v5.3.8","v5.3.9","v5.4.0","v5.4.1","v5.4.2","v5.4.3","v5.4.4","v6.0.0","v6.0.0-RC-1","v6.0.0-RC-2","v6.0.0-RC-3","v6.0.0-RC-4","v6.0.0-RC-5","v6.0.0-RC-6","v6.0.0-RC-7","v6.0.0-RC-8","v6.0.1","v6.0.10","v6.0.11","v6.0.12","v6.0.13","v6.0.14","v6.0.2","v6.0.3","v6.0.4","v6.0.5","v6.0.6","v6.0.7","v6.0.8","v6.0.9","v6.1.0","v6.1.1","v6.1.2","v6.2.0","v6.2.1","v6.2.2","v6.2.3","v6.3.0","v6.3.1","v6.3.2","v6.3.3","v6.3.4","v6.4.0","v6.4.1","v6.4.2","v7.0.0","v7.0.1","v7.0.10","v7.0.11","v7.0.12","v7.0.13","v7.0.2","v7.0.3","v7.0.4","v7.0.5","v7.0.6","v7.0.7","v7.0.8","v7.0.9","v7.1.14","v7.1.15","v7.1.16","v7.1.17","v8.0.0","v8.0.1","v8.0.2","v8.0.3","v8.0.4","v8.1.0","v8.1.1","v8.1.15","v8.1.16","v8.1.17","v8.1.18","v8.1.2","v8.1.3","v8.1.4","v8.2.0","v8.2.1","v8.3.0","v8.3.1","v8.3.2","v8.3.3","v8.3.4","v8.3.5","v8.3.6","v8.3.7","v8.4.0","v8.4.1","v8.5.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-j5g3-42wp-gqm3/GHSA-j5g3-42wp-gqm3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
