CVE-2026-63293 Arbitrary File Read/Write: metadata.yaml symlink in image allows host filesystem access as root

A link following vulnerability in LXD allows an attacker to achieve arbitrary file read and write operations on the host system. When importing or unpacking an image archive, LXD fails to validate whether the metadata.yaml file is a symbolic link. An attacker can exploit this flaw by providing a...

CVE-2026-63293

The CVE-2026-63293 entry concerns LXD: during image import/unpack, metadata.yaml is not validated as a symlink, enabling a crafted image archive to point to host filesystem paths. This can allow arbitrary file read and write on the host, escalating to full access via symlink traversal. The descri...

CVE-2026-73409

Budibase Open Source platform suffered a filesystem information disclosure via builder-controlled TLS options. Before 3.40.1, packages/server/src/integrations/mongodb.ts passed tlsCertificateKeyFile and tlsCAFile values directly to MongoClient on Budibase Cloud. A malicious builder could submit a...

CVE-2026-73409 Budibase: Server Filesystem Existence/Read Oracle via Builder-Controlled MongoDB tlsCertificateKeyFile

Budibase is an open-source low-code platform. Prior to 3.40.1, packages/server/src/integrations/mongodb.ts passed builder-controlled tlsCertificateKeyFile and tlsCAFile values directly to MongoClient on Budibase Cloud.

CVE-2026-68448

A flaw was found in the Linux kernel's overlayfs component. When copying files across different overlay filesystems, the system incorrectly checked read permissions using the destination filesystem's credentials instead of the source's. This oversight could allow an unauthorized user to read file...

CVE-2026-68442

A flaw was found in the btrfs filesystem component of the Linux kernel. When an extent map is split, a flag EXTENTFLAGLOGGING is incorrectly propagated to the new split maps. This issue occurs because the flag clearing operation was applied to the wrong variable during the splitting process...
