This means that `` tags will be converted to iframes instead the next time the page is saved, which may break any pages that rely upon previously saved `` tags. Developers can override this configuration if desired to revert to the original behaviour.\n\nWe reviewed the potential impact of this vulnerability within the context of Silverstripe CMS. We concluded this is a medium impact vulnerability given how TinyMCE is used by Silverstripe CMS.\n\n### References:\n- https://www.silverstripe.org/download/security-releases/ss-2024-001\n- https://github.com/advisories/GHSA-5359-pvf2-pw78\n\n","public_affected_ranges":["ECOSYSTEM: introduced 0; fixed 5.2.16"]}],"null_published_at":"2026-10-31T22:13:05.876Z","source_updated_at":"2024-12-01T05:37:28.631Z","source_disclosed_at":"2024-07-17T16:00:48.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:41:49.675Z"}],"next_cursor":null,"snapshot_revision":"42594"}
