Summary
Craft CMS 5.0.0-RC1 through 5.10.5 contains an incorrect authorization vulnerability. A control-panel user holding only the viewCategories permission (without saveCategories) for a category group can permanently modify that group's category structure — reordering and re-parenting categories — via the structures/move-element action. The structureEditable flag is computed from the view permission rather than the save permission, and the StructuresController authorizes the mutating action on that read-time session grant without a save re-check. Because a category's URI is derived from its position in the structure, moving a category changes its URL and those of its descendants and can corrupt navigation menus built from the category taxonomy. The issue is fixed in 5.10.6.
Risk Assessment
Risk of unauthorized modification of category structure, potentially leading to broken navigation, URL changes, and integrity issues.
Recommendation
Update Craft CMS to version 5.10.6 or later, which includes the fix. Additionally, review user permissions and restrict access to the structures/move-element action.
