Risk summary
Not in the CISA KEV catalog. EPSS exploit probability 2.3%. CVSS 8.8 (High).
This CVE is among the lower half of tracked Microsoft CVEs by EPSS exploit probability.
On-premises SharePoint remains one of the most attacked Microsoft server products, and this remote code execution flaw touches every supported branch: 2016, 2019, and Subscription Edition. The 2% EPSS score and absence from CISA KEV suggest no active exploitation, but SharePoint RCEs have a history of being weaponized once proof-of-concept code appears.
Do this: Patch internet-facing SharePoint servers today and keep internal farms in the same maintenance window.
