CVE-2026-124430

Craft CMS from 5.10.0 before 5.11.2 contains an authorization bypass vulnerability that allows authenticated low-privileged users to browse volumes they lack permissions for. Attackers can delete a linked asset and use the replacement volume browser modal to view directory structures of all volumes, though not file contents.

Craft CMS from 5.0.0 before 5.11.2 contains a privilege escalation vulnerability that allows unauthenticated public registrants to reclaim deactivated non-admin accounts while retaining their direct permissions. Attackers can register using a deactivated account, set a new password, and inherit permissions stored in userpermissions_users, enabling privileged account takeover when email verification is disabled.

Craft CMS from 5.7.0 before 5.11.2 contains an arbitrary file read vulnerability that allows authenticated control panel users to read SVG files by posting arbitrary paths to the app/icon-svg endpoint. Attackers can supply aliases or absolute paths, which are resolved without permission checks, to read any SVG-content file readable by the PHP process, including files outside the Craft installation.

Craft CMS from 5.0.0 before 5.11.2 contains an authorization bypass vulnerability that allows unauthenticated attackers to read content from sites outside a GraphQL schema's Sites scope. Attackers can send a POST request to /actions/graphql/api selecting the localized field without the siteId argument to disclose out-of-scope site content.

Craft 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.

Craft 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 and set a new password, enabling complete control-panel takeover.

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 replacePeerFiles permission is never enforced, allowing an authenticated low-privilege author with replaceFiles permission to overwrite peer asset files.

Craft CMS versions >= 5.0.0-RC1 and < 5.10.11 fail to perform an independent authorization check in ElementsController::actionDeleteForSite(). The method checks permissions only against the user's own provisional draft, then deletes the canonical element without re-checking, allowing an authenticated user without deleteEntriesForSite permission to hard-delete entries.

Craft 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.

Craft CMS versions before 5.10.11 contain a site scope bypass vulnerability in GraphQL entry mutation resolvers that fail to validate siteId through ArgumentManager::prepareArguments(). Attackers with tokens scoped to one site can read, modify, or delete entries across unauthorized sites.
