{"id":"GHSA-43cq-c2gq-pfpw","summary":"Craft CMS: Authorization bypass in `entries/move-to-section` via missing target-section save check","details":"### Summary\n\nThe `EntriesController::actionMoveToSection()` endpoint checks only whether the current user can view the destination section, but it does not require permission to save entries into that section. A low-privileged authenticated control-panel user who can move an entry out of its current section can therefore move that entry into a different section where they have read access but no write access.\n\n### Details\n\nThe vulnerable route is implemented in [EntriesController.php](/D:/files/projects/cms-5.9.19/cms-5.9.19/src/controllers/EntriesController.php):465:\n\nThe destination check is only `viewEntries:$section-\u003euid` . The source-entry gate is `Entry::canMove()`, which verifies whether the user can move the existing entry based on the source section:\n\nThis closes the exploit chain:\n\n1. External source: authenticated CP request to `entries/move-to-section`.\n2. Missing authorization check: destination section requires only `viewEntries`, not `saveEntries`.\n3. Privileged sink: `moveEntryToSection()` rewrites `sectionId` and saves the entry into the unauthorized section.\n\nPreconditions derived from the code:\n\n1. The attacker is authenticated to the control panel.\n2. Entry `345` is movable by the attacker from its current section.\n3. The attacker can satisfy `viewEntries` on destination section `12`.\n4. The attacker does not have `saveEntries:DESTINATION_UID`, which is the missing check that makes the bypass possible.\n\nResult:\n\n1. The controller accepts the request because `viewEntries:$section-\u003euid` passes.\n2. Each source entry passes `canMove()` based on source-section permissions.\n3. `moveEntryToSection()` updates the entry’s `sectionId` and saves it.\n4. The entry is now located in a section where the attacker did not have write permission.\n\n### Impact\n\nThis breaks the intended section-level authorization model. A user with limited content permissions can inject or relocate content into a protected section, interfering with editorial boundaries, approval workflows, section-specific business logic, and content ownership expectations.","aliases":["CVE-2026-50280"],"modified":"2026-09-10T03:51:10.214512171Z","published":"2026-07-02T18:47:37Z","database_specific":{"nvd_published_at":"2026-07-02T00:16:44Z","cwe_ids":["CWE-284"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-07-02T18:47:37Z"},"references":[{"type":"WEB","url":"https://github.com/craftcms/cms/security/advisories/GHSA-43cq-c2gq-pfpw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50280"},{"type":"WEB","url":"https://github.com/craftcms/cms/commit/0a6b916f6367b0162b2eaf2366add67b45fa98ea"},{"type":"PACKAGE","url":"https://github.com/craftcms/cms"}],"affected":[{"package":{"name":"craftcms/cms","ecosystem":"Packagist","purl":"pkg:composer/craftcms/cms"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0-RC1"},{"fixed":"5.9.21"}]}],"versions":["5.0.0","5.0.0-RC1","5.0.1","5.0.2","5.0.3","5.0.4","5.0.5","5.0.6","5.1.0","5.1.1","5.1.10","5.1.2","5.1.3","5.1.4","5.1.5","5.1.6","5.1.7","5.1.8","5.1.9","5.2.0","5.2.0-beta.1","5.2.0-beta.2","5.2.0-beta.3","5.2.0-beta.4","5.2.0-beta.5","5.2.0-beta.6","5.2.1","5.2.10","5.2.2","5.2.3","5.2.4","5.2.4.1","5.2.5","5.2.6","5.2.7","5.2.8","5.2.9","5.3.0","5.3.0-beta.1","5.3.0-beta.2","5.3.0.1","5.3.0.2","5.3.0.3","5.3.1","5.3.2","5.3.3","5.3.4","5.3.5","5.3.6","5.4.0","5.4.0.1","5.4.1","5.4.10","5.4.10.1","5.4.2","5.4.3","5.4.4","5.4.5","5.4.5.1","5.4.6","5.4.7","5.4.7.1","5.4.8","5.4.9","5.5.0","5.5.0.1","5.5.1","5.5.1.1","5.5.10","5.5.2","5.5.3","5.5.4","5.5.5","5.5.6","5.5.6.1","5.5.7","5.5.8","5.5.9","5.6.0","5.6.0.1","5.6.0.2","5.6.1","5.6.10","5.6.10.1","5.6.10.2","5.6.11","5.6.12","5.6.13","5.6.14","5.6.15","5.6.16","5.6.17","5.6.2","5.6.3","5.6.4","5.6.5","5.6.5.1","5.6.6","5.6.7","5.6.8","5.6.9","5.6.9.1","5.7.0","5.7.0-beta.1","5.7.0-beta.2","5.7.1","5.7.1.1","5.7.10","5.7.11","5.7.2","5.7.3","5.7.4","5.7.5","5.7.6","5.7.7","5.7.8","5.7.8.1","5.7.8.2","5.7.9","5.8.0","5.8.1","5.8.10","5.8.11","5.8.12","5.8.13","5.8.13.1","5.8.13.2","5.8.14","5.8.15","5.8.16","5.8.17","5.8.18","5.8.19","5.8.2","5.8.20","5.8.21","5.8.22","5.8.23","5.8.3","5.8.4","5.8.5","5.8.6","5.8.7","5.8.8","5.8.9","5.9.0","5.9.0-beta.1","5.9.0-beta.2","5.9.1","5.9.10","5.9.11","5.9.12","5.9.13","5.9.14","5.9.15","5.9.16","5.9.17","5.9.18","5.9.19","5.9.2","5.9.20","5.9.3","5.9.4","5.9.5","5.9.6","5.9.7","5.9.8","5.9.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-43cq-c2gq-pfpw/GHSA-43cq-c2gq-pfpw.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
