Descrição técnica

borgbackup is an opensource, deduplicating archiver with compression and authenticated encryption. Prior to 1.4.5 and 2.0.0b22, extracting a malicious archive can follow a symlinked parent path or resolve embedded dot-dot path components and delete or overwrite files outside the extraction directory. A crafted slave hardlink can also use an attacker-controlled hardlink source outside the extraction directory and hard-link that file into the restored tree, disclosing its contents. Creating the malicious archive requires repository access and, for encrypted or authenticated repositories, the Borg key and passphrase; a victim must then extract the archive. This issue is fixed in versions 1.4.5 and 2.0.0b22.

———LXC is a userspace interface for the Linux kernel containment features used to create and manage system containers. In LXC 7.0.0 and earlier, lxc-copy and the public liblxc clone() API can follow attacker-controlled symbolic links while updating /etc/hostname in a copied container root filesystem. The affected surfaces are lxc-copy and liblxc's public lxc_container::clone() API. The privileged cloning process must run as root. The source rootfs must be attacker-controlled or less trusted. A symlink can be placed at etc/hostname or in an intermediate component. The clone operation preserves the symlink before updating the hostname. The vulnerable write truncates and overwrites an existing file outside the destination rootfs. When root clones an untrusted container without LXC_CLONE_KEEPNAME, the copied symlink can resolve outside the destination rootfs and cause the privileged process to overwrite an existing host file with the destination container name. Unprivileged use and managers with independent cloning implementations are not affected. LXC_CLONE_KEEPNAME avoids the hostname update and therefore the affected write.6h CVE-2026-870087.1 ALT

———Code Graph RAG is an AI-powered knowledge graph and retrieval system for querying, understanding, and editing multi-language codebases. Prior to 0.0.589, AstGrepService in codebase_rag/tools/ast_grep_service.py enumerates files beneath project_root and relies on should_skip_path in codebase_rag/utils/path_utils.py to classify them, but the containment check operates on unresolved lexical paths. A symbolic link planted inside an analyzed repository can therefore reference a file outside the configured root while still appearing in scope. The structural_search tool follows the link and discloses readable content without an approval gate, while structural_replace with dry_run=False follows it and overwrites writable content; the MCP path invokes structural replacement without the agent-loop approval control. An attacker who causes a victim to analyze a repository containing such a link can read credentials, keys, environment files, or sibling source and can modify files accessible to the code-graph-rag process. This issue is fixed in version 0.0.589.7h CVE-2026-1121106.3 MÉD

——0A time-of-check to time-of-use race condition in the SafeNet Authentication Client (SAC) SACSrv log-cleanup function can allow an authenticated, non-administrator local user to redirect a privileged file deletion operation outside the intended log directory. This issue affects SAC releases up to and including 10.9 R3 GA (build 10.9.7449).8h CVE-2026-1217475.5 MÉD

——2Node Version Manager (nvm) is a POSIX-compliant shell function for managing multiple node.js versions. In versions 0.2.0 through 0.40.8, nvm does not check whether `.nvmrc` is a symbolic link. A repository or archive that ships `.nvmrc` as a symlink to another file (for example `../../.npmrc`, or `/proc/self/environ` on Linux) makes a plain `nvm use`, `nvm install`, `nvm which`, `nvm exec`, `nvm run`, or `nvm-exec` read that file and print its contents in the invalid-`.nvmrc` message (even with `--silent`) or, for a one-line file, in the `Found ... with version <...>` message; with the README's zsh `load-nvmrc` or bash `cdnvm` hook installed, entering the directory is enough. nvm sends the content nowhere; the attacker learns it only where they can see the victim's output, such as a CI log for a contributed branch. Version 0.41.0 still follows a symlinked `.nvmrc`, so deliberate links to another version file keep working, but never prints its content, and accepts it only if it contains a version or the name of an existing alias; the README's bash `cdnvm` hook, which read `.nvmrc` itself, now gets the version from nvm, so users of that hook must also update their copy of it.1d CVE-2026-1217465.5 MÉD

——2Node Version Manager (nvm) is a POSIX-compliant shell function for managing multiple node.js versions. In versions 0.40.0 through 0.40.8, `nvm use --save` and `nvm install --save` (or `-w`) write the resolved version to `$PWD/.nvmrc` with `tee`, which follows a symbolic link. A repository that commits `.nvmrc` as a symlink to a path outside itself (git recreates the link on clone) therefore makes `--save` truncate any file the user can write, such as a shell startup file or `~/.ssh/authorized_keys`, and replace its contents with the version string, or create the target of a dangling link; the link itself is left unchanged, so `git status` stays clean. The attacker does not control the content written, so this is data loss, not code execution. Version 0.41.0 refuses, with a warning, to write when `.nvmrc` in the current directory is a symlink, dangling or not, rather than writing through it or replacing it.1d CVE-2026-1222354.7 MÉD

——2Jan from 0.8.5 before 0.8.8 contains a workspace guard bypass vulnerability in the agent-tools gate.rs that allows attackers to write files outside the workspace via dangling symlinks. Attackers supplying a malicious repository can use prompt injection to make the write or edit tools follow symlinks, creating files like ~/.ssh/authorized_keys on the host.1d
