CVE-2026-113620: In Eclipse ioFog Controller versions 3.8.0 through 3.9.1, operator WebSocket upgrades on the exec and log routes do not verify the bearer JWT. The payload is decoded and its groups or roles are used as RBAC subjects. A self-minted token whose groups contain admin matches the built-in admin role, with no account and no RoleBinding. The attacker can open an exec or log session for a microservice or fog whose UUID they already know. HTTP routes are not affected: they verify the token before RBAC. Agent WebSockets verify the fog token and are not affected.
The exploitability of CVE-2026-113620 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2026-113620 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-113620, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-113620, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
