CVE-2026-102596: Nango is an open-source platform for connecting agents and products to third-party APIs. Prior to 0.70.9, on accounts with RBAC enabled through a plan with has_rbac=true, two private flow-read routes, GET /api/v1/integrations/:providerConfigKey/flows and GET /api/v1/flow/:flowName, apply webAuth but omit can({ action: 'read', resource: 'flow', scopedBy: envScope }). A same-team user with the development_full_access role can therefore request env=prod and read production integration flow metadata or named flow configuration despite being denied by guarded production routes. Both controllers use res.locals.environment from the authenticated account, so the issue bypasses the production role boundary but does not cross tenant boundaries. This issue is fixed in version 0.70.9 and managed-1.5.11-0.70.8-aae30d044d7e229807d51a3957c212f3fb689e1a
The exploitability of CVE-2026-102596 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).
CVE-2026-102596 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
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-2026-102596, 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-2026-102596, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
