AnalysisAI
Unauthenticated access control bypass in Fortinet FortiWeb - spanning the 7.0 line through 8.0.2 - and multiple FortiOS branches stems from an incomplete list of disallowed inputs (CWE-184), allowing remote attackers to circumvent input-filtering enforcement and achieve unauthorized integrity modifications. The vulnerability extends to FortiOS, implicating shared blocklist logic across Fortinet's platform stack according to EUVD-2026-57192 and CPE data. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates no authentication, no user interaction, no special network position, and no elevated attack complexity are required - exploitation is achievable by any remote unauthenticated actor who can reach the FortiWeb service over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.8 (Medium) is anchored by a fully network-accessible, unauthenticated attack path (AV:N/AC:L/PR:N/UI:N) with scope unchanged and impact confined to low integrity (I:L), reflecting no confidentiality or availability loss per available data. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The CVSS temporal Remediation Level of RL:O confirms Fortinet has released an official fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
