Workaround
Unknown. No documented workaround found.
Exploitation
- No evidence of active exploitation found. - CISA KEV status: not verified directly. - No public proof of concept found. - Do not confuse with CVE-2026-124194, a separate Outlook flaw that Microsoft marked as exploited in the same update cycle.
Our recommendation
- Install the November 2026 Office and Outlook updates as a priority. - Verify the installed build on each device against the fixed versions on the MSRC advisory. - Until patched, filter unsolicited email attachments and links. - Monitor for exploitation and for vendor updates to this CVE.
