External Control of File Name or Path

Grav versions before 1.10.55 contain a path traversal vulnerability in the admin plugin's Save As action that fails to validate the language code parameter. An authenticated admin user with admin.pages.create permission can supply directory traversal sequences in the lang POST field to write arbitrary .md files outside the pages directory with attacker-controlled content.Show less

The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.134 does not validate a user supplied path before using it in a file deletion routine, allowing administrators to delete arbitrary files on the server, including files outside the web root.Show less

The Frontend Admin by DynamiApps WordPress plugin before 3.29.13 does not properly validate a user-controllable directory path before deleting files within it, allowing unauthenticated attackers to delete index.php and .htaccess files outside the intended directory, including the WordPress root, which can render the site inoperable. Successful exploitation requires a non-default form configuration.Show less

OpenList a file list program that supports multiple storage. Prior to 4.2.3, OpenList's offline-download feature at POST /api/fs/add_offline_download with tool: "SimpleHttp" accepts an attacker-supplied URL and saves its bytes under a per-task temporary directory before transferring them to the user's destination storage. The temporary filename comes from the attacker-controlled Content-Disposition header, is passed from parseFilenameFromContentDisposition in internal/offline_download/http/util.go to filepath.Join(task.TempDir, filename) in SimpleHttp.Run in internal/offline_download/http/client.go, and is opened with os.Create without a containment check. Because filepath.Join cleans .. segments, a non-admin user with PermAddOfflineDownload on any path can traverse out of task.TempDir and create, truncate, or overwrite any file writable by the OpenList process whose parent directory already exists. The server/handles/offline_download.go AddOfflineDownload route uses normal user authentication rather than AuthAdmin, and local-storage destinations fall through tryPutUrl in internal/offline_download/tool/add.go to the vulnerable SimpleHttp.Run path. This issue is fixed in version 4.2.3.Show less

DbGate fails to validate jslid parameters in the jsldata controller, allowing authenticated users to read and write arbitrary files via file:// scheme resolution. Attackers can exploit getJslFileName() to bypass directory containment and access sensitive files including encrypted database credentials stored in connections configuration.Show less

AVideo through commit c91b5975d contains a cross-site request forgery and path traversal vulnerability in stopLive.php that allows attackers to delete directories by exploiting missing token validation and unsanitized key parameter concatenation. Attackers can craft an image tag with a traversal payload like key=../../videos to trigger recursive deletion of the videos directory when an admin visits a malicious page.Show less

WWBN AVideo contains a path traversal vulnerability in the API get_api_login_code endpoint that allows unauthenticated attackers to delete arbitrary .log files by supplying directory traversal sequences in the code parameter. Attackers can exploit this to destroy audit logs and probe for file existence on the server, with the vulnerability enabling both file deletion and information disclosure about the filesystem.Show less

Laravel Excel provides supercharged Excel exports and imports in Laravel. From 3.1.8 until 3.1.70, in src/Files/Disk.php the Maatwebsite\Excel\Files\Disk::copy() method resolves the caller-controlled $destination supplied through Excel::store(), $export->store(), or storeExcel() against the process working directory with realpath() instead of the configured filesystem disk. If the path names an existing writable file, Disk::copy() opens it with fopen() in rb+ mode and uses stream_copy_to_stream(), bypassing Flysystem path confinement and allowing an attacker whose application input controls the export path to overwrite arbitrary existing files with export content. The rb+ behavior creates a non-truncating overwrite and trailing bytes when the new export is shorter, and overwriting an executable PHP file can lead to remote code execution. This issue is fixed in version 3.1.70.Show less

An authenticated arbitrary file write vulnerability exists in AOS-CX. Successful exploitation could allow an authenticated malicious actor, under specific conditions outside the attacker's control and following a required action by another user, to create or modify arbitrary files and execute arbitrary commands as a privileged user on the underlying operating system.Show less

Insecure file operations in the API of HPE Networking Fabric Composer could allow an authenticated remote attacker to achieve remote code execution. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system.Show less

An arbitrary file write vulnerability exists in the API of HPE Networking Fabric Composer and could allow an authenticated administrative user to escalate privileges. Successful exploitation of this vulnerability may enable the attacker to execute arbitrary system commands with root privileges on the underlying operating system.Show less

pnpm is a package manager. Prior to 10.34.5 and 11.11.0, pnpm accepts a scoped path traversal in a tarball dependency's package.json manifest name because pnpm11/resolving/npm-resolver/src/pickPackage.ts rejects slash characters only for unscoped names. During pnpm install, the unvalidated name reaches raw path joins in pnpm11/installing/deps-resolver/src/resolvePeers.ts, pnpm11/installing/deps-resolver/src/index.ts, and pnpm11/deps/graph-builder/src/lockfileToDepGraph.ts, causing package extraction outside node_modules and allowing attacker-controlled files to overwrite arbitrary filesystem paths even when --ignore-scripts is used. The overwrite can replace shell startup files, Git hooks, or installed package code and lead to code execution. This issue is fixed in versions 10.34.5, and 11.11.0.Show less

oasdiff is a command-line and Go package that compares and detects breaking changes in OpenAPI specs. From version 1.13.2 through version 1.18.0, oasdiff did not enforce --allow-external-refs=false (library: openapi3.Loader.IsExternalRefsAllowed = false) when loading a spec from a git revision (the rev:path form, e.g. main:openapi.yaml). External $refs were resolved on that load path even when external refs were explicitly disabled, so the mitigation silently did not apply there. This issue has been patched in version 1.18.1.Show less

nodemailer before 9.0.1 fails to apply disableFileAccess and disableUrlAccess flags to message-level raw option, allowing authenticated attackers to read arbitrary files or perform server-side request forgery by supplying path or href properties. Attackers can exploit this by crafting raw messages with file paths or URLs that bypass the intended sandbox, with fetched content delivered in the outgoing message to attacker-controlled recipients.Show less

browser-use web-ui versions 2.0.0 through 3.0.0 fail to validate browser settings paths in run_agent_task, allowing attackers to create directories at arbitrary locations by supplying absolute paths to save_recording_path, save_trace_path, save_agent_history_path, or save_download_path parameters. Attackers can exploit this via the unauthenticated Gradio interface to create directories anywhere the root-running container has write access.Show less

The shared-files-pro WordPress plugin before 1.7.70 does not validate the file path supplied when creating a featured image, allowing unauthenticated attackers to read arbitrary files from the server and republish their contents at a public URL.Show less

The Shared Files WordPress plugin before 1.7.67, shared-files-pro WordPress plugin before 1.7.68 do not properly sanitize a file path taken from a frontend file submission and their single-pass traversal filter is bypassable, allowing unauthenticated users to store a path that points outside the uploads directory. When the corresponding file entry is later permanently deleted, an arbitrary file on the server (such as wp-config.php) is deleted, leading to denial of service and potential site takeover.Show less

Trilium is an open-source hierarchical note-taking application. In versions prior to 0.104.0, the automatic image-download feature accepts file:// URLs in a note's img tags and reads the referenced local file with no path validation, allowing any authenticated user to disclose arbitrary files readable by the Trilium process. When a text note is saved, Trilium scans its HTML for image sources and downloads each external one; because the HTML sanitizer keeps file as an allowed scheme, a source such as file:///etc/passwd is passed straight to a filesystem read and its contents are stored as a note attachment the user can then retrieve. Pointing the same primitive at an unbounded source such as /dev/zero causes uncontrolled memory allocation that crashes the server process. The feature is enabled by default and is reachable through the web UI, the ETAPI, the web clipper, and note imports, requiring only an authenticated session or an ETAPI token. This issue is fixed in version 0.104.0Show less

NLTK through 3.10.3 contains a path traversal vulnerability in model-artifact APIs that bypass pathsec enforcement by using raw file operations on caller-controlled paths. Attackers can read or write files outside allowed sandbox roots through TransitionParser, AveragedPerceptron, PerceptronTagger, and maxent parameter APIs when pathsec is enabled.Show less
