CVE-2023-45372Network attack vector

Item changes via omitted edit filter

Published Oct 9, 2023 · Updated Sep 19, 2024

Edit-filter bypass in Wikibase before 1.35.12, 1.36.x before 1.39.5, and 1.40.x before 1.40.1 allows remote attackers to merge items. ItemMergeInteractor writes the source-clearing and target-update revisions through WikiPageEntityStore without running the EditFilterMergedContent hook. Normal merge permissions still apply, but a blocking AbuseFilter stops only redirect creation after the first two revisions have already changed both items.
