CVE-2026-20960 is a vulnerability classified under CWE-285 (Improper Authorization) found in Microsoft Power Apps version 1710 (9.2.23071.136). This flaw allows an attacker who already has some level of authorization within the Power Apps environment to execute arbitrary code remotely over a network. The vulnerability arises due to insufficient authorization checks within the application, enabling privilege escalation or unauthorized actions beyond the attacker's intended permissions. The CVSS v3.1 score of 8.0 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L) and user interaction (UI:R). The impact includes full compromise of confidentiality, integrity, and availability (C:H/I:H/A:H). Although no exploits are currently known in the wild, the vulnerability poses a significant risk to organizations relying on Power Apps for business-critical workflows and data processing. The lack of available patches at the time of publication necessitates immediate risk mitigation through compensating controls. The vulnerability's presence in a widely used Microsoft product highlights the importance of vigilant monitoring and rapid response to emerging threats.

For European organizations, the impact of CVE-2026-20960 can be severe. Power Apps is commonly used across various sectors including finance, healthcare, government, and manufacturing for custom business applications and automation. Exploitation could lead to unauthorized code execution, resulting in data breaches, manipulation of business processes, or disruption of services. Confidential and sensitive data processed within Power Apps could be exposed or altered, undermining compliance with GDPR and other data protection regulations. The attack requires some privileges and user interaction, which means insider threats or compromised credentials could facilitate exploitation. The broad use of Microsoft products in Europe increases the attack surface, and critical infrastructure relying on Power Apps workflows could face operational risks. Additionally, the high severity score indicates potential for widespread damage if exploited at scale.

1. Immediately inventory and identify all instances of Microsoft Power Apps version 1710 (9.2.23071.136) within the organization. 2. Apply official patches or updates from Microsoft as soon as they become available; monitor Microsoft security advisories closely. 3. Restrict user privileges within Power Apps to the minimum necessary, enforcing the principle of least privilege to reduce the risk of exploitation. 4. Implement multi-factor authentication (MFA) for all users accessing Power Apps to mitigate risks from compromised credentials. 5. Monitor Power Apps logs and network traffic for unusual activities indicative of exploitation attempts, such as unexpected code execution or privilege escalations. 6. Segment networks to isolate critical Power Apps environments from broader corporate networks, limiting lateral movement. 7. Conduct user awareness training focusing on the risks of social engineering and the importance of cautious interaction with Power Apps workflows. 8. Review and harden authorization policies within Power Apps configurations to ensure strict access controls. 9. Prepare incident response plans specific to Power Apps compromise scenarios to enable rapid containment and recovery.
