CISA KEV (Known Exploited Vulnerabilities)
For the benefit of the cybersecurity community and network defenders—and to help every organization better manage vulnerabilities and keep pace with threat activity—CISA maintains the authoritative source of vulnerabilities that have been exploited in the wild.
Microsoft SharePoint contains a code injection vulnerability that could allow an authorized attacker to execute code over a network. This vulnerability could be chained with CVE-2025-49706. The update for CVE-2025-53770 includes more robust protections than the update for CVE-2025-49704.
CISA recommends disconnecting public-facing versions of SharePoint Server that have reached their end-of-life (EOL) or end-of-service (EOS). For example, SharePoint Server 2013 and earlier versions are end-of-life and should be discontinued if still in use. For supported versions, please follow the mitigations according to CISA and vendor instructions. Adhere to the applicable BOD 22-01 guidance for cloud services or discontinue use of the product if mitigations are not available.
