CVE-2026-0234 is a high-severity improper verification of cryptographic signature vulnerability in the Microsoft Teams Marketplace integration for Cortex XSOAR and Cortex XSIAM. The flaw affects integration versions 1.5.0 through 1.5.51 and allows the affected platforms to accept a forged or spoofed cryptographic signature during Microsoft Teams integration workflows. Because signature validation is not performed correctly, a remote attacker can submit crafted requests that are treated as trusted by the integration. The issue is exploitable over the network, requires no authentication, and does not require user interaction. Successful exploitation enables unauthorized access to protected resources and unauthorized modification of data handled through the integration, including security-relevant content processed by the affected platforms.
