VWE-2021-6191 Viewing Source [template]Vulnerability | aka= | severity=High | difficulty=Easy | description=Permissions Escalation and Data Loss. Some edits do not preserve existing custom field values from the previous edit. This is most common for edits generated from outside the Edit tab, such as mass edits. Within the Edit tab, when a user who does not have permission to change any custom field for a page edits that page, the unpermitted custom fields may be changed to a blank value. | platform=XF2 | lite=no | issueid= | discover-date=August 8, 2021 | patch-date=September 14, 2021 | patches=4.1.2 Patch Level 2 4.1.1 Patch Level 7 4.1.0 Patch Level 9 | workaround= [/template] 672 characters
