Exploitation Conditions

Exploitation requires the attacker to hold valid authenticated credentials on an affected FortiSOAR instance (PR:L) - FortiSOAR PaaS or on-premise versions 7.6.0-7.6.2, 7.5.0-7.5.1, and all 7.4 and 7.3 releases. The attacker must send specifically crafted requests to endpoints that fail to enforce proper access controls (CWE-284). Limiting factors: no code execution, modification, or disruption is possible (I:N/A:N) - impact is confined to reading data the account should not access; a valid account is mandatory, so fully anonymous/external attackers cannot exploit it, and it does not apply to versions outside the listed ranges. The exact feature or request type is not specified in the available data.

Impact

This is a moderate-severity, authenticated information-disclosure flaw (CVSS 6.5) whose signals align consistently toward lower-priority-but-legitimate rather than emergency. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N confirms network reachability with low attack complexity but requires at least low-level authenticated access (PR:L), and limits impact to confidentiality only (C:H, I:N, A:N) - no integrity or availability loss. EPSS is low at 0.26% (17th percentile), there is no CISA KEV listing and no public proof-of-concept identified, so exploitation status is 'no public exploit identified at time of analysis.' No SSVC decision data was provided in the input. All signals agree this is a real but non-urgent issue: prioritize it as part of normal patch cycles rather than as an actively-exploited emergency. One data tension to note: the input Tag 'Authentication Bypass' conflicts with both the description ('authenticated attacker') and the CVSS PR:L metric - this is improper access control by an already-authenticated user, not a pre-auth authentication bypass; treat the 'Authentication Bypass' label as suspect pending vendor confirmation.

Exploit ScenarioDerived

An attacker who already holds a valid low-privileged FortiSOAR account (PaaS or on-premise, versions 7.3 through 7.6.2) sends crafted API/HTTP requests that bypass object-level access controls, returning data belonging to other tenants, users, or privilege levels they should not be able to read. No public exploit code is known, but the low attack complexity (AC:L) means a knowledgeable authenticated user could likely reproduce it once the specific endpoint is identified.

AnalysisAIv1 – Oct 14, 2026

Information disclosure in Fortinet FortiSOAR (PaaS and on-premise) 7.3, 7.4, 7.5.0-7.5.1, and 7.6.0-7.6.2 allows an authenticated attacker with a valid low-privileged account to read data they are not authorized to access by sending crafted requests to endpoints that fail to enforce proper access controls. Impact is limited to confidentiality (C:H) with no integrity or availability effect, and a valid account is mandatory (CVSS vector PR:L), so fully anonymous external attackers cannot exploit it. No public exploit code or confirmed active exploitation has been identified at time of analysis, and EPSS is low (0.26%, 17th percentile), consistent with a moderate-severity, authenticated-only issue (CVSS 6.5).

RemediationAI

Consult Fortinet PSIRT advisory FG-IR-25-601 (https://fortiguard.fortinet.com/psirt/FG-IR-25-601) for the exact fixed release and upgrade path; the provided data does not include a specific patched version number, so do not assume one. Because exploitation requires a valid authenticated account (PR:L), prioritize reducing the attack surface by removing or disabling unused accounts, enforcing least privilege so that low-privileged users cannot reach data outside their role, and auditing role and permission assignments on FortiSOAR PaaS and on-premise instances. If upgrade cannot be performed immediately, restrict network access to the FortiSOAR management and API interfaces to trusted management networks or VPNs, and monitor logs for unusual or crafted request patterns from authenticated users; the trade-off is that tighter network restrictions may inconvenience legitimate remote users, and stricter role restrictions may block legitimate workflows, so validate changes in a test environment. No vendor-released patch version is specified in the provided input, and no public exploit code has been identified.

Technical ContextAI · show details

FortiSOAR is a security orchestration, automation, and response (SOAR) platform deployed either as a PaaS offering or on-premise, used to ingest, correlate, and act on security events through playbooks, APIs, and integrations. The flaw is classified as CWE-284 (Improper Access Control), meaning the application fails to correctly enforce authorization checks on certain request paths or features, allowing an authenticated user with limited privileges to retrieve data that should be restricted to higher-privileged roles. The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N confirms network reachability, low attack complexity, a required low-privileged account, no user interaction, and a high confidentiality impact with no integrity or availability impact. The CPE entries cpe:2.3:a:fortinet:fortisoar:*:*:*:*:*:*:*:* are version-wildcarded, matching the vendor advisory’s broad affected version ranges rather than pinpointing a single build. No code execution, data modification, or service disruption is possible from this defect; the exposure is confined to reading data the account should not access.

Attack Technique

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
