CVE-2026-72817

A flaw was found in the go-chi/chi component. The RealIP middleware, responsible for resolving the request source IP, does not properly validate trusted proxies when processing the X-Forwarded-For header. A remote attacker can exploit this by prepending a forged IP address to the X-Forwarded-For...

CVE-2026-12631

CVE-2026-12631 is a broken access-control flaw in the Zephyr RTOS kernel affecting the k_thread_join() and k_thread_abort() syscall validation path in kernel/thread.c. The root cause is a logic inversion: K_SYSCALL_VERIFY_MSG treats a non-zero (error) return as success, so the access-denied branc...

CVE-2026-12631 Broken access-control denial in k_thread_join/k_thread_abort syscall validation in Zephyr kernel

The Zephyr kernel validates the kthreadjoin and kthreadabort system calls declared syscall in include/zephyr/kernel.h through threadobjvalidate in kernel/thread.c. Its default switch branch is the access-denied path, taken when kobjectvalidate returns -EPERM the calling user thread was never...

CVE-2026-53759 linuxfabrik-lib: Insecure creation of SQLite databases

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations. Prior to version 4.2.0, dbsqlite.py created SQLite databases at predictable paths in the shared /tmp directory and followed attacker-created symbolic links at those paths. An attacker who...

CVE-2026-53759

In linuxfabrik-lib versions before 4.2.0, db_sqlite.py created SQLite databases at predictable /tmp paths and followed attacker-created symlinks. A compromised local account (e.g., nagios) could create a symlink and trigger a sudo-authorized plugin, causing a root process to write to arbitrary pa...
