Copilot Studio
Monthly
Privilege elevation in Microsoft Copilot Studio lets a network-based, unauthenticated attacker bypass cryptographic signature verification (CWE-347) to gain elevated privileges across a scope boundary, per CVSS:3.1 AV:N/PR:N/S:C rated 10.0. The flaw appears to involve forged or improperly validated JWT tokens, per the 'Jwt Attack' tagging, and because Copilot Studio is a multi-tenant cloud service the scope-change vector implies impact beyond the initially compromised authority. No public exploit identified at time of analysis, and EPSS is low at 0.29% (22nd percentile), but SSVC rates technical impact as total and automatable as yes.
Unauthenticated attackers can remotely access sensitive information in Microsoft Copilot Studio due to improper access controls, requiring no authentication or user interaction. This network-based vulnerability exposes confidential data to unauthorized disclosure with no patch currently available.
Improper neutralization of input during web page generation ('Cross-site Scripting') in Copilot Studio by an unauthorized attacker leads to elevation of privilege over a network. Rated critical severity (CVSS 9.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Exposure of Sensitive Information to an Unauthorized Actor in Copilot Studio allows a unauthenticated attacker to view sensitive information through network attack vector. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
An authenticated attacker can bypass Server-Side Request Forgery (SSRF) protection in Microsoft Copilot Studio to leak sensitive information over a network. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity.
