Summary
A vulnerability was detected in 0-Gaurav-0 nexus-mcp version aed0026e7ac1f23dc940e46e9fd3a2da6904f914 in the function child_process.exec of the file src/auth/browser.ts of the nexus_reauth MCP tool component. Manipulation of the argument url results in command injection. The attack can be performed remotely and the exploit is now public.
Risk Assessment
A remote attacker could execute arbitrary system commands on the server, potentially leading to full system compromise. The project has not responded to the report, so a fix may not be available.
Recommendation
Monitor the project repository for a fix and consider restricting access to the MCP tool. Until fixed, implement URL validation and permission restrictions.

- CVE-2026-123614Critical
imgproxy from 4.0.0 before 4.0.16 contains an integer overflow in the ICO loader that allows remote attackers to trigger a heap buffer overflow via a crafted data_size value. Attackers can submit a crafted ICO image whose data_size wraps the allocation in vips/icoload.c, corrupting heap memory to crash the process or achieve code execution.
- CVE-2026-123551Critical
OpenAM from 14.0.0 before 16.1.4 contains an information disclosure vulnerability that allows unauthenticated attackers to read live session tokens from the notification WebSocket. Attackers can bypass the agent-only check through an unvalidated internal forward on legacy Liberty ID-FF endpoints, collecting iPlanetDirectoryPro tokens to hijack user and administrator sessions.
- CVE-2026-123550Critical
OpenAM before 16.1.4 contains an authentication bypass vulnerability in its SAML v2.0 service provider that accepts unsigned assertions on the ECP (PAOS) and HTTP-Artifact bindings when WantAssertionsSigned is false. Unauthenticated remote attackers can submit forged assertions to obtain sessions as any mapped user, including administrators, and hijack single sign-on to dependent applications.
- CVE-2026-123549Critical
OpenAM before 16.1.4 fails to enforce the Valid Creation Attributes list during self-registration, allowing anonymous attackers to set restricted attributes including group membership. Attackers can register through the legacy self-service REST endpoint or User Self-Service flow to join administrative groups and gain full administrative control of OpenAM.
