| CVE-2026-34078 | 1 Flatpak | 1 Flatpak | 2026-04-24 | 10.0 Critical |
| Flatpak is a Linux application sandboxing and distribution framework. Prior to 1.16.4, the Flatpak portal accepts paths in the sandbox-expose options which can be app-controlled symlinks pointing at arbitrary paths. Flatpak run mounts the resolved host path in the sandbox. This gives apps access to all host files and can be used as a primitive to gain code execution in the host context. This vulnerability is fixed in 1.16.4. | ||||
| CVE-2026-39861 | 2 Anthropic, Anthropics | 2 Claude Code, Claude Code | 2026-04-23 | 10.0 Critical |
| Claude Code is an agentic coding tool. Prior to version 2.1.64, Claude Code's sandbox did not prevent sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code subsequently wrote to a path within such a symlink, its unsandboxed process followed the symlink and wrote to the target location outside the workspace without prompting the user for confirmation. This allowed a sandbox escape where neither the sandboxed command nor the unsandboxed app could independently write outside the workspace, but their combination could write to arbitrary locations, potentially leading to code execution outside the sandbox. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window to trigger sandboxed code execution via prompt injection. Users on standard Claude Code auto-update have received this fix automatically. Users performing manual updates are advised to update to version 2.1.64 or later. | ||||
| CVE-2026-23968 | 1 Copier-org | 1 Copier | 2026-04-18 | 5.5 Medium |
| Copier is a library and CLI app for rendering project templates. Prior to version 9.11.2, Copier suggests that it's safe to generate a project from a safe template, i.e. one that doesn't use unsafe features like custom Jinja extensions which would require passing the `--UNSAFE,--trust` flag. As it turns out, a safe template can currently include arbitrary files/directories outside the local template clone location by using symlinks along with `_preserve_symlinks: false` (which is Copier's default setting). Version 9.11.2 patches the issue. | ||||
| CVE-2026-23986 | 1 Copier-org | 1 Copier | 2026-04-18 | 7.1 High |
| Copier is a library and CLI app for rendering project templates. Prior to version 9.11.2, Copier suggests that it's safe to generate a project from a safe template, i.e. one that doesn't use unsafe features like custom Jinja extensions which would require passing the `--UNSAFE,--trust` flag. As it turns out, a safe template can currently write to arbitrary directories outside the destination path by using directory a symlink along with `_preserve_symlinks: true` and a generated directory structure whose rendered path is inside the symlinked directory. This way, a malicious template author can create a template that overwrites arbitrary files (according to the user's write permissions), e.g., to cause havoc. Version 9.11.2 patches the issue. | ||||
| CVE-2026-24047 | 1 Backstage | 1 Backstage | 2026-04-18 | 6.3 Medium |
| Backstage is an open framework for building developer portals, and @backstage/cli-common provides config loading functionality used by the backend and command line interface of Backstage. Prior to version 0.1.17, the `resolveSafeChildPath` utility function in `@backstage/backend-plugin-api`, which is used to prevent path traversal attacks, failed to properly validate symlink chains and dangling symlinks. An attacker could bypass the path validation via symlink chains (creating `link1 → link2 → /outside` where intermediate symlinks eventually resolve outside the allowed directory) and dangling symlinks (creating symlinks pointing to non-existent paths outside the base directory, which would later be created during file operations). This function is used by Scaffolder actions and other backend components to ensure file operations stay within designated directories. This vulnerability is fixed in `@backstage/backend-plugin-api` version 0.1.17. Users should upgrade to this version or later. Some workarounds are available. Run Backstage in a containerized environment with limited filesystem access and/or restrict template creation to trusted users. | ||||
| CVE-2026-1386 | 1 Amazon | 1 Firecracker | 2026-04-18 | 6 Medium |
| A UNIX symbolic link following issue in the jailer component in Firecracker version v1.13.1 and earlier and 1.14.0 on Linux may allow a local host user with write access to the pre-created jailer directories to overwrite arbitrary host files via a symlink attack during the initialization copy at jailer startup, if the jailer is executed with root privileges. To mitigate this issue, users should upgrade to version v1.13.2 or 1.14.1 or above. | ||||
| CVE-2026-21916 | 2 Juniper, Juniper Networks | 2 Junos, Junos Os | 2026-04-17 | 7.3 High |
| A UNIX Symbolic Link (Symlink) Following vulnerability in the CLI of Juniper Networks Junos OS allows a local, authenticated attacker with low privileges to escalate their privileges to root which will lead to a complete compromise of the system. When after a user has performed a specific 'file link ...' CLI operation, another user commits (unrelated configuration changes), the first user can login as root. This issue affects Junos OS: * all versions before 23.2R2-S7, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S3, * 24.4 versions before 24.4R2-S2, * 25.2 versions before 25.2R2. This issue does not affect versions 25.4R1 or later. | ||||
| CVE-2026-27485 | 1 Openclaw | 1 Openclaw | 2026-04-17 | 4.4 Medium |
| OpenClaw is a personal AI assistant. In versions 2026.2.17 and below, skills/skill-creator/scripts/package_skill.py (a local helper script used when authors package skills) previously followed symlinks while building .skill archives. If an author runs this script on a crafted local skill directory containing symlinks to files outside the skill root, the resulting archive can include unintended file contents. If exploited, this vulnerability can lead to potential unintentional disclosure of local files from the packaging machine into a generated .skill artifact, but requires local execution of the packaging script on attacker-controlled skill contents. This issue has been fixed in version 2026.2.18. | ||||
| CVE-2026-27976 | 2 Zed, Zed-industries | 2 Zed, Zed | 2026-04-17 | 8.8 High |
| Zed, a code editor, has an extension installer allows tar/gzip downloads. Prior to version 0.224.4, the tar extractor (`async_tar::Archive::unpack`) creates symlinks from the archive without validation, and the path guard (`writeable_path_from_extension`) only performs lexical prefix checks without resolving symlinks. An attacker can ship a tar that first creates a symlink inside the extension workdir pointing outside (e.g., `escape -> /`), then writes files through the symlink, causing writes to arbitrary host paths. This escapes the extension sandbox and enables code execution. Version 0.224.4 patches the issue. | ||||
| CVE-2026-25724 | 2 Anthropic, Anthropics | 2 Claude Code, Claude Code | 2026-04-16 | 7.5 High |
| Claude Code is an agentic coding tool. Prior to version 2.1.7, Claude Code failed to strictly enforce deny rules configured in settings.json when accessing files through symbolic links. If a user explicitly denied Claude Code access to a file (such as /etc/passwd) and Claude Code had access to a symbolic link pointing to that file, it was possible for Claude Code to read the restricted file through the symlink without triggering deny rule enforcement. This issue has been patched in version 2.1.7. | ||||
| CVE-2026-24018 | 1 Fortinet | 2 Forticlient, Forticlientlinux | 2026-04-16 | 7.4 High |
| A UNIX symbolic link (Symlink) following vulnerability in Fortinet FortiClientLinux 7.4.0 through 7.4.4, FortiClientLinux 7.2.2 through 7.2.12 may allow a local and unprivileged user to escalate their privileges to root. | ||||
| CVE-2026-39860 | 2 Linux, Nixos | 2 Linux Kernel, Nix | 2026-04-15 | 9 Critical |
| Nix is a package manager for Linux and other Unix systems. A bug in the fix for CVE-2024-27297 allowed for arbitrary overwrites of files writable by the Nix process orchestrating the builds (typically the Nix daemon running as root in multi-user installations) by following symlinks during fixed-output derivation output registration. This affects sandboxed Linux builds - sandboxed macOS builds are unaffected. The location of the temporary output used for the output copy was located inside the build chroot. A symlink, pointing to an arbitrary location in the filesystem, could be created by the derivation builder at that path. During output registration, the Nix process (running in the host mount namespace) would follow that symlink and overwrite the destination with the derivation's output contents. In multi-user installations, this allows all users able to submit builds to the Nix daemon (allowed-users - defaulting to all users) to gain root privileges by modifying sensitive files. This vulnerability is fixed in 2.34.5, 2.33.4, 2.32.7, 2.31.4, 2.30.4, 2.29.3, and 2.28.6. | ||||
| CVE-2026-34446 | 2 Linuxfoundation, Onnx | 2 Onnx, Onnx | 2026-04-15 | 4.7 Medium |
| Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to version 1.21.0, there is an issue in onnx.load, the code checks for symlinks to prevent path traversal, but completely misses hardlinks because a hardlink looks exactly like a regular file on the filesystem. This issue has been patched in version 1.21.0. | ||||
| CVE-2026-34447 | 2 Linuxfoundation, Onnx | 2 Onnx, Onnx | 2026-04-15 | 5.5 Medium |
| Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to version 1.21.0, there is a symlink traversal vulnerability in external data loading allows reading files outside the model directory. This issue has been patched in version 1.21.0. | ||||
| CVE-2025-55345 | 1 Openai | 1 Codex | 2026-04-15 | 8.8 High |
| Using Codex CLI in workspace-write mode inside a malicious context (repo, directory, etc) could lead to arbitrary file overwrite and potentially remote code execution due to symlinks being followed outside the allowed current working directory. | ||||
| CVE-2024-52522 | 1 Rclone | 1 Rclone | 2026-04-15 | 6.8 Medium |
| Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Insecure handling of symlinks with --links and --metadata in rclone while copying to local disk allows unprivileged users to indirectly modify ownership and permissions on symlink target files when a superuser or privileged process performs a copy. This vulnerability could enable privilege escalation and unauthorized access to critical system files, compromising system integrity, confidentiality, and availability. This vulnerability is fixed in 1.68.2. | ||||
| CVE-2025-53881 | 2 Exim, Opensuse | 2 Exim, Tumbleweed | 2026-04-15 | N/A |
| A UNIX Symbolic Link (Symlink) Following vulnerability in logrotate config in the exim package allowed privilege escalation from mail user/group to root.This issue affects Tumbleweed: from ? before 4.98.2-lp156.248.1. | ||||
| CVE-2024-47515 | 2026-04-15 | 8.1 High | ||
| A vulnerability was found in Pagure. Support of symbolic links during repository archiving of repositories allows the disclosure of local files. This flaw allows a malicious user to take advantage of the Pagure instance. | ||||
| CVE-2023-6597 | 2 Python Software Foundation, Redhat | 8 Cpython, Enterprise Linux, Openshift and 5 more | 2026-04-15 | 7.8 High |
| An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances. | ||||
| CVE-2025-14693 | 1 Ugreen | 1 Dh2100+ | 2026-04-15 | 6.2 Medium |
| A vulnerability has been found in Ugreen DH2100+ up to 5.3.0. This affects an unknown function of the component USB Handler. Such manipulation leads to symlink following. The attack can be executed directly on the physical device. The exploit has been disclosed to the public and may be used. It is suggested to upgrade the affected component. | ||||
