Even so, because the flaw relies on a CSRF vector that does not require complex prerequisites, an attacker who can induce a user\u2019s browser to send a request to the delete_async endpoint could delete files without needing administrative credentials. The risk remains significant for sites that rely on the integrity of media assets, and the potential impact warrants immediate attention."}}}}, "created": "2026-03-12T09:56:44.828785+00:00", "updated": "2026-03-20T15:29:19.453571+00:00", "vendors": ["emlog", "emlog$PRODUCT$emlog"]}
