ContextForge: DNS TOCTOU race condition causes SSRF protection bypass (`/admin/gateways/test`)

SummaryThe /admin/gateways/test endpoint validates submitted URLs by resolving the hostname at validation time and blocking private address ranges. The HTTP client independently re-resolves DNS at connection time with no IP binding between the two operations, creating a TOCTOU window exploitable...

CVE-2026-49415

A TOCTOU race condition exists in the FreeBSD kernel during the execve(2) system call when executing a SUID binary . The kernel installs the new virtual address space before updating process credentials, creating a window where a local unprivileged user (running as the same user) can access and m...

CVE-2026-49415 Local privilege escalation via execve(2) TOCTOU race

During execve2 of a SUID binary, the new virtual address space is installed before the process credentials are updated. During this window, a process running as the same user can access the target process's memory via procfs or linprocfs, because the kernel's debugging permission check still saw...
