CVE-2026-0234: CWE-347 Improper Verification of Cryptographic Signature in Palo Alto Networks Cortex XSOAR Microsoft Teams Marketplace
CVE-2026-0234 is a high-severity vulnerability in Palo Alto Networks Cortex XSOAR Microsoft Teams Marketplace version 1.5.0. It involves improper verification of cryptographic signatures during Microsoft Teams integration, allowing unauthenticated users to access and modify protected resources.
AI Analysis
Technical Summary
This vulnerability (CWE-347) in Cortex XSOAR and Cortex XSIAM platforms arises from improper verification of cryptographic signatures when integrating Microsoft Teams. The flaw enables unauthenticated attackers to bypass security controls and gain unauthorized access to protected resources, potentially modifying them. The CVSS 4.0 base score is 7.2, reflecting network attack vector with high complexity and partial attack requirements. No official patch or remediation guidance is currently available from the vendor, and no known exploits are reported in the wild.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to access and modify protected resources within the affected Cortex XSOAR Microsoft Teams integration. This could lead to unauthorized data manipulation or disclosure, impacting the confidentiality and integrity of the system's resources.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected integration and monitor for suspicious activity related to Microsoft Teams integrations in Cortex XSOAR environments.
