Descripción técnica

Craft CMS versions >= 5.0.0-RC1 and < 5.10.11 contain a missing authorization vulnerability in AssetsController::actionReplaceFile. When a request supplies sourceAssetId and targetFilename but omits assetId, the target asset is resolved by folder and filename after the permission checks execute, so the replacePeerFiles permission is never enforced. An authenticated low-privilege author with only the replaceFiles permission on a shared folder can overwrite the content of a peer's asset file (located in the same folder) with attacker-controlled bytes. Fixed in 5.10.11.

——0Kimai versions from 2.61.0 before 2.63.0 fail to disable admin-only work-contract preferences for low-privilege users in the PATCH /api/users/{id}/preferences endpoint. Although the web interface gates these employment-contract fields behind the contract_other_profile admin permission, the WorkContractPreferenceSubscriber (introduced in 2.61.0) registers the preferences as enabled without a permission check, so an authenticated regular user can use the API to modify their own admin-only work-contract data. The issue is fixed in 2.63.0 by applying the same permission check to the API endpoint.3h CVE-2026-848024.3 MED

——0Craft CMS versions from 5.7.0 before 5.10.12 contain an information disclosure vulnerability in AssetsController::actionMoveInfo that fails to enforce volume permissions. Authenticated control panel users can submit POST requests to the assets/move-info endpoint with arbitrary folderIds to retrieve asset count and total storage size for volumes they cannot access.3h CVE-2026-848018.8 ALT

——0Craft CMS versions before 5.10.11 fail to validate admin status in the actionGetPasswordResetUrl endpoint, allowing non-admin users with administrateUsers permission to mint password reset URLs for administrator accounts. Attackers can generate a valid reset URL for any admin user and set a new password via actionSetPassword, which validates only the verification code without checking the caller's session, enabling complete control-panel takeover.3h CVE-2026-847987.1 ALT

——0Craft CMS versions >= 5.0.0-RC1 and < 5.10.11 fail to perform an independent authorization check in ElementsController::actionDeleteForSite(). The method loads an element with checkForProvisionalDraft enabled and runs the deletion authorization check against the user's own provisional draft (which only verifies draft ownership), then propagates the deletion to the canonical element without re-checking permissions. As a result, an authenticated user who has viewEntries, viewPeerEntries, saveEntries, savePeerEntries, and editSite permissions but lacks the deleteEntriesForSite permission can hard-delete a canonical entry's site record (and, for single-site entries, the full element and content), which is irrecoverable via Craft's recycle bin.3h CVE-2026-847976.3 MED

——0Craft CMS versions before 5.10.11 contain an authorization bypass vulnerability in ElementsController::actionDuplicate() that allows authenticated users with createEntries permission to delete peer provisional drafts. Attackers can exploit the deleteProvisionalDraft parameter to delete another user's unsaved draft without proper authorization checks, gaining access to the victim's in-progress content.3h
