Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-53760 is a server-side request forgery vulnerability (CWE-918) in Microsoft Office SharePoint. The flaw received a CVSS 3.1 base score of 7.1 reflecting network attack vector, low attack complexity, and low privileges required.

An authorized attacker can send crafted requests over a network to the affected SharePoint instance and thereby elevate privileges, achieving high confidentiality impact together with limited integrity impact and no user interaction.

The official advisory is published at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-53760. The associated EPSS score has remained flat at 0.0286 with no material increase since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
