CVE-2025-53762 is a high-severity Permissive List of Allowed Inputs (CWE-183) vulnerability in Microsoft Purview. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 49% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Microsoft Purview contains a permissive list of allowed inputs tracked as CWE-183 that produces the vulnerability described in CVE-2025-53762. The flaw permits an authorized attacker to elevate privileges across a network and carries a CVSS 3.1 base score of 8.7 reflecting network attack vector, low complexity, high-privilege requirement, and changed scope with high impact to confidentiality and integrity.
An attacker already holding high privileges can send crafted inputs over the network to expand access beyond the intended authorization boundary, achieving broad control over affected Purview resources without user interaction.
Microsoft publishes mitigation guidance and patch information for this issue in its Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-53762. The associated EPSS score remains low, moving only from 0.0178 to a peak of 0.0189.

Mitigating Controls (NIST 800-53 r5) AI
Strict validity checks on inputs directly stop overly permissive allow lists from being used as the protection mechanism.

Secure SDLC practices directly require rigorous allow-list design and testing that prevents permissive input validation.

Security testing can detect overly broad allow-lists, but does not inherently prevent their creation.
Application security requirements can mandate strict, minimal allow-lists and input validation rules that prevent overly permissive lists.
Secure system architecture and engineering principles require explicit, least-privilege input validation designs that directly address permissive allow-lists.
Secure coding standards enforce rigorous input validation and reject unsafe values, mitigating permissive allow-list weaknesses.
Configuration management can enforce validated input rules, yet does not directly address the design flaw of permissive lists.
