CVE-2026-13208

A flaw was found in KubeVirt's virt-handler domain notify server. The gRPC handlers for HandleDomainEvent and HandleK8SEvent derive the VMI identity namespace/name solely from the request body without validating it against the connection's origin. Each virt-launcher pod connects through a per-VMI...

CVE-2026-13201

A flaw was found in KubeVirt's safepath package used by virt-handler. The OpenAtNoFollow function uses OPATH|ONOFOLLOW to obtain a file descriptor to a path leaf, but downstream operations resolve the path via /proc/self/fd/N using link-following syscalls. When the leaf is a symlink, the kernel...

StrikeShark: investigating a new campaign delivering Cobalt Strike through SharkLoader

Introduction During our research of activity affecting a diplomatic organization in Indonesia, we uncovered a previously undocumented malware family that we have named SharkLoader. What initially appeared to be an isolated case quickly expanded into a broader campaign as we identified additional...

UNIX Symbolic Link (Symlink) Following

Overview Affected versions of this package are vulnerable to UNIX Symbolic Link Symlink Following in the OpenAtNoFollow process. An attacker can cause unintended file ownership or permission changes on host files by placing a symlink in the virt-launcher filesystem, which is then followed via...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication in the notify server process. An attacker can disrupt the lifecycle management of co-located virtual machines by sending forged domain lifecycle events through a legitimate Unix socket after gaining shell access...

DOMPurify: Permanent `ALLOWED_ATTR` pollution via `setConfig()` bypassing the hook clone-guard (incomplete fix of the 3.4.7 hook-pollution patch)

Summary DOMPurify 3.4.7 shipped a security fix "permanent hook pollution" that makes a registered uponSanitizeAttribute hook's mutation of data.allowedAttributes non-persistent — so allowing an attribute for one element does not leak into later sanitize calls. The fix clones ALLOWEDATTR inside...
