CVE-2026-59185 is a high-severity cross-tenant authorization bypass in Identrail's GitHub App connection-completion workflow before version 1.0.2. The workflow validates that a pending connection state belongs to the authenticated caller's tenant, workspace, and project, but accepts a client-controlled GitHub App installation identifier without verifying that the installation belongs to the organization authorized for that workspace. The supplied identifier is persisted as the workspace's GitHub connection. Identrail can subsequently use its GitHub App credentials to mint an installation token for that linked installation. The feature-flagged V2 connector path reportedly contains the same unbound installation-identifier flaw and additionally resolves pending connectors by state without fully rechecking caller scope. The weakness is classified as CWE-639 and CWE-862.

A high-severity vulnerability affecting the github.com/identrail/identrail library and related packages prior to version 1.0.2. It has CVSS v3 base score 8.5 and is associated with CWE-639 and CWE-862.
A cross-tenant insecure direct object reference (IDOR) in identrail's GitHub App connection-completion flow. The endpoint accepts an attacker-controlled GitHub App installation_id without ownership validation, allowing an authenticated tenant to mint an installation token for another tenant's installation and access the victim organization's private repository inventory and metadata.
A high-severity cross-tenant authorization-bypass vulnerability in Identrail's GitHub App connection-completion flow. An authenticated tenant can provide another customer's GitHub App installation ID, causing Identrail to mint an installation token and expose the victim organization's private repository inventory, metadata, and potentially repository content through posture scans or repository reads.
