Descripción técnica

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.

———FairEmail is a fully featured, open source, privacy-friendly email app for Android. Prior to 1.2325, shared attachment handling does not adequately sanitize an attacker-controlled filename before constructing its destination path. A local attacker-controlled app can therefore supply path components that escape the intended shared attachment directory and overwrite or corrupt files in the FairEmail private data directory, including account or message databases. Exploitation requires app lock using PIN or biometric authentication and user interaction to unlock FairEmail. This issue is fixed in version 1.2325.5h CVE-2026-1029436.5 MED

———Dagu is a workflow engine with a built-in Web user interface. Prior to version 2.11.0, its MCP dagu_read operation with target dag_spec invokes the DAG specification API directly, bypassing the HTTP middleware introduced for CVE-2026-33344. The underlying resolver does not restrict resolved paths to configured DAG directories. An authenticated attacker with a viewer-role API key can supply an absolute or traversing path to read .yaml or .yml files outside those directories that are accessible to the Dagu process. The affected operation does not provide write or execution capability. This issue is fixed in version 2.11.0.5h CVE-2026-100395—

———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-2026-62268—

———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 2.0.0b22.7h CVE-2026-776047.5 ALT

——0Code Graph RAG is an AI-powered knowledge graph and retrieval system for querying, understanding, and editing multi-language codebases. Prior to 0.0.345, the MCPToolsRegistry.read_file implementation in codebase_rag/mcp/tools.py joins attacker-controlled file_path input to project_root without resolving and verifying containment when offset or limit selects the paginated branch. An absolute path causes pathlib to discard the configured root, while relative traversal can also resolve outside it. The protected non-paginated branch uses validate_project_path, but the paginated branch bypasses that validation before opening the path. An unauthenticated caller of a network-exposed HTTP MCP server can therefore read arbitrary UTF-8-readable files available to the server process, including credentials, environment data, private keys, source, and configuration; local callers through the stdio transport can reach the same vulnerable code path. This issue is fixed in version 0.0.345.8h CVE-2026-632137.2 ALT

——0SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the Upgrade Wizard commit flow trusts the hidden zip_to_dir parameter, while clean_path() does not reject traversal sequences. An authenticated administrator can copy extracted package files outside the intended destination, overwrite application or configuration files, place executable PHP under the web root, or cause denial of service. This issue is fixed in versions 7.15.2 and 8.10.2.9h
