Vulnerability Reportelectronuserland/builder:24-wine-mono

This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker with access to the container's rendering or input paths could trigger out-of-bounds memory access in the Mesa GPU stack or escalate to root code execution inside the container via CVE-2026-50292 or CVE-2026-40393, and the image ships a full build/desktop toolchain rather than a minimal runtime, so a large share of the 781 exposed findings sits directly in the deployed surface. Note that CVE-2026-50292 requires local access to crafted uinput devices, and the WebGPU allocation path in CVE-2026-40393 is only reachable when untrusted data drives GPU memory allocation. The 333 post-exploit-only findings all fall below severity 6.0 and only matter after an initial compromise, but they should not be read as eliminating the need to rebuild on a fresher base.
