Summary

CVE-2026-22155 is a medium-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Fortinet Fortisoar. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires cryptographic protection to ensure confidentiality and integrity of sensitive information transmitted by FortiSOAR, eliminating the cleartext exposure described in CWE-319.

prevent

Mandates use of approved cryptographic mechanisms for all sensitive data transmissions, directly blocking the cleartext channel vulnerability in FortiSOAR versions 7.3-7.6.

prevent

Enforces boundary protections (e.g., TLS inspection or proxy rules) that can prevent unencrypted sensitive flows from FortiSOAR to external systems or users.

PR.DS-02 full match
prevents

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Specifying encryption and other security technology for network services prevents transmission of sensitive information in cleartext over potentially untrusted channels.

prevents

Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.

mitigates

Specifying communications-security requirements and secure remote-access methods (including encryption expectations) prevents the transmission of sensitive data in cleartext over home or public networks.

mitigates

Armoured conduits, electromagnetic shielding and locked enclosures make passive eavesdropping on unencrypted traffic traversing the cables more difficult, mitigating exposure of sensitive data in transit.
