CVE-2021-41133 log

Severity High
Remote No
Type Sandbox escape
A security issue has been found in Flatpak before version 1.12.0. An anonymous reporter discovered that Flatpak apps with direct access to AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can trick portals and other host-OS services into treating the Flatpak app as though it was an ordinary, non-sandboxed host-OS process, by manipulating the VFS using recent mount-related syscalls that are not blocked by Flatpak's denylist seccomp filter, in order to substitute a crafted /.flatpak-info or make that file disappear entirely.
