Descripción técnica

A flaw was found in the QEMU Guest Agent (qga). A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use (TOCTOU) file-symlink race. Successful exploitation allows the attacker to gain ownership of arbitrary root-owned files or directories, leading to root access. This vulnerability requires an external management layer (e.g., libvirt) to trigger the affected code path.

——1A UNIX Symbolic Link (Symlink) Following vulnerability in openSUSE Tumbleweed suricata package allows the suricata user to escalate to root. This issue affects openSUSE Tumbleweed: from ? before 8.0.5-2.1; openSUSE Tumbleweed: from ? before 8.0.5-2.1.6d CVE-2026-398227.8 ALT

——2On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, 'root.Open("symlink/")' will open "symlink" even when "symlink" is a symbolic link pointing outside of the root.8d CVE-2026-146993.3 BAJ

——1A weakness has been identified in zcaceres markdownify-mcp up to 1.1.0. The affected element is the function assertPathAllowed of the file src/Markdownify.ts. Executing a manipulation can lead to symlink following. The attack can only be executed locally. The pull request to fix this issue awaits acceptance.15d CVE-2026-534896.5 MED

——3containerd is an open-source container runtime. Versions prior to 2.3.2, 2.2.5 and 2.1.9 contain a bug where the CRI plugin restores container.log from a checkpoint image without validating a symlinked path. This could result in reading an arbitrary file on the host via kubectl logs. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.19d CVE-2026-415793.3 BAJ

——4runc is a CLI tool for spawning and running containers according to the OCI specification. In versions prior to 1.3.6, 1.4.0-rc.1, 1.4.0-rc.12, 1.5.0-rc.1, and 1.5.0-rc.1, when setting up the container rootfs, setupPtmx and setupDevSymlinks call os.Remove and os.Symlink with a filepath.Join string which allow an image with /dev as a symlink to trick runc into deleting files called ptmx on the host or creating a hardcoded set of symlinks with specific names and targets in an arbitrary pre-existing host directory. This issue is not exploitable under Docker, because Docker creates a top-level read-only layer that masks any malicious /dev symlink present in the container image — unlike some other Linux container tooling, whose higher-level runtimes built on runc remain exposed to exploitation via a malicious image. This issue has been fixed in versions 1.3.6, 1.4.3 and 1.5.0.19d CVE-2026-137486.3 MED

——1Improper restriction of file path resolution in Snowflake CLI versions prior to 3.19 allowed arbitrary local file content to be read and transmitted to Snowflake services. An attacker could exploit this by supplying crafted repository or project content that referenced files outside the intended project boundary, causing Snowflake CLI to read local files and upload or embed their contents during deployment or SQL template processing. Successful exploitation required the victim to process attacker-controlled project content, and retrieval of exfiltrated data depended on access to the victim's Snowflake account artifacts such as query history or uploaded stage content. The fix is available in Snowflake CLI version 3.19, and users must manually upgrade.21d
