CVE-2026-6940 High · 7.1 CWE-22 Apr 23, 2026

radare2 < 6.1.4 Project Deletion Path Traversal Directory Deletion

radare2 prior to 6.1.4 contains a path traversal vulnerability in project deletion that allows local attackers to recursively delete arbitrary directories by supplying absolute paths that escape the configured dir.projects root directory. Attackers can craft absolute paths to project marker files outside the project storage boundary to cause recursive deletion of attacker-chosen directories with permissions of the radare2 process, resulting in integrity and availability loss.

CVE-2026-41205 High · 7.5 CWE-22 Apr 23, 2026

Mako: Path traversal via double-slash URI prefix in TemplateLookup

Mako is a template library written in Python. Prior to 1.3.11, TemplateLookup.get_template() is vulnerable to path traversal when a URI starts with // (e.g., //../../../secret.txt). The root cause is an inconsistency between two slash-stripping implementations. Any file readable by the process can be returned as rendered template content when an application passes untrusted input directly to TemplateLookup.get_template(). This vulnerability is fixed in 1.3.11.

CVE-2026-6903 High · 7.5 CWE-22 Apr 23, 2026

Path Traversal Vulnerability in LabOne User Interface

The LabOne Web Server, backing the LabOne User Interface, contains insufficient input validation in its file access functionality. An unauthenticated attacker could exploit this vulnerability to read arbitrary files on the host system that are accessible to the operating system user running the LabOne software. Additionally, the Web Server does not sufficiently restrict cross-origin requests, which could allow a remote attacker to trigger file access from a victim's browser by directing the victim to a malicious website. The vulnerability is only exploitable when the LabOne Web Server is running. Installations using only the LabOne APIs without starting the Web Server are not exposed.

CVE-2026-41211 Critical · 10.0 CWE-22 Apr 22, 2026

`vite-plus/binding` has path traversal `downloadPackageManager()` that leads to writes outside of `VP_HOME`

Vite+ is a unified toolchain and entry point for web development. Prior to version 0.1.17, `downloadPackageManager()` accepts an untrusted `version` string and uses it directly in filesystem paths. A caller can supply `../` segments or an absolute path to escape the `VP_HOME/package_manager/<pm>/` cache root and make Vite+ delete, replace, and populate directories outside the intended cache location. Version 0.1.17 contains a patch.

CVE-2026-41180 High · 7.5 CWE-22 Apr 22, 2026

PsiTransfer: Upload PATCH path traversal can create `config.<NODE_ENV>.js` and lead to code execution on restart

PsiTransfer is an open source, self-hosted file sharing solution. Prior to version 2.4.3, the upload PATCH flow under `/files/:uploadId` validates the mounted request path using the still-encoded `req.path`, but the downstream tus handler later writes using the decoded `req.params.uploadId`. In deployments that use a supported custom `PSITRANSFER_UPLOAD_DIR` whose basename prefixes a startup-loaded JavaScript path, such as `conf`, an unauthenticated attacker can create `config.<NODE_ENV>.js` in the application root. The attacker-controlled file is then executed on the next process restart. Version 2.4.3 contains a patch.

CVE-2026-4917 Medium · 4.9 CWE-22 Apr 22, 2026

IBM Guardium Data Protection is affected by multiple vulnerabilities

IBM Guardium Data Protection 12.1 could allow an administrative user to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to write arbitrary files on the system.

CVE-2026-33656 Critical · 9.1 CWE-22 Apr 22, 2026

EspoCRM vulnerable to authenticated RCE via Formula with path traversal in attachment `sourceId`, exploitable by admin user

EspoCRM is an open source customer relationship management application. Prior to version 9.3.4, EspoCRM's built-in formula scripting engine allowing updating attachment's sourceId thus allowing an authenticated admin to overwrite the `sourceId` field on `Attachment` entities. Because `sourceId` is concatenated directly into a file path with no sanitization in `EspoUploadDir::getFilePath()`, an attacker can redirect any file read or write operation to an arbitrary path within the web server's `open_basedir` scope. Version 9.3.4 fixes the issue.

CVE-2026-34414 High · 7.1 Public exploit CWE-22 Apr 22, 2026

Xerte Online Toolkits Path Traversal via connector.php

Xerte Online Toolkits versions 3.15 and earlier contain a relative path traversal vulnerability in the elFinder connector endpoint at /editor/elfinder/php/connector.php where the name parameter in rename commands is not sanitized for path traversal sequences. Attackers can supply a name value containing directory traversal sequences to move files from project media directories to arbitrary locations on the filesystem, potentially overwriting application files, achieving stored cross-site scripting, or combining with other vulnerabilities to achieve unauthenticated remote code execution by moving PHP code files to the application root.

CVE-2026-35363 Medium · 5.6 CWE-22 Apr 22, 2026

uutils coreutils rm Safeguard Bypass via Improper Path Normalization

A vulnerability in the rm utility of uutils coreutils allows the bypass of safeguard mechanisms intended to protect the current directory. While the utility correctly refuses to delete . or .., it fails to recognize equivalent paths with trailing slashes, such as ./ or .///. An accidental or malicious execution of rm -rf ./ results in the silent recursive deletion of all contents within the current directory. The command further obscures the data loss by reporting a misleading 'Invalid input' error, which may cause users to miss the critical window for data recovery.

CVE-2026-35338 High · 7.3 CWE-22 Apr 22, 2026

uutils coreutils chmod Path Traversal Bypass of --preserve-root

A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbolic links to execute destructive recursive operations (e.g., chmod -R 000) on the entire root filesystem, leading to system-wide permission loss and potential complete system breakdown.

CVE-2026-32885 Critical · 9.1 CWE-22 Apr 22, 2026

DDEV has ZipSlip path traversal in tar and zip archive extraction

DDEV is an open-source tool for running local web development environments for PHP and Node.js. Versions prior to 1.25.2 have unsanitized extraction in both `Untar()` and `Unzip()` functions in `pkg/archive/archive.go`. Downloads and extracts archives from remote sources without path validation. Version 1.25.2 patches the issue.

CVE-2026-6855 High · 7.1 CWE-22 Apr 22, 2026

Instructlab: instructlab: path traversal allows arbitrary directory creation and file write

A flaw was found in InstructLab. A local attacker could exploit a path traversal vulnerability in the chat session handler by manipulating the `logs_dir` parameter. This allows the attacker to create new directories and write files to arbitrary locations on the system, potentially leading to unauthorized data modification or disclosure.

CVE-2026-4280 Medium · 6.5 CWE-22 Apr 22, 2026

Breaking News WP <= 1.3 - Missing Authorization to Authenticated (Subscriber+) Local File Inclusion/Read

The Breaking News WP plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.3. This is due to the brnwp_ajax_form AJAX endpoint lacking both authorization checks and CSRF verification, combined with insufficient path validation when the brnwp_theme option value is passed directly to an include() statement in the brnwp_show_breaking_news_wp() shortcode handler. While sanitize_text_field() is applied to user input, it does not strip directory traversal sequences (../). This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the brnwp_theme option with a directory traversal payload (e.g., ../../../../etc/passwd) and subsequently trigger file inclusion of arbitrary files on the server when the shortcode is rendered.

CVE-2026-41062 Medium · 6.5 CWE-22 Apr 21, 2026

WWBN/AVideo has an incomplete fix for a directory traversal bypass via query string in ReceiveImage downloadURL parameters

WWBN AVideo is an open source video platform. In versions 29.0 and below, the directory traversal fix introduced in commit 2375eb5e0 for `objects/aVideoEncoderReceiveImage.json.php` only checks the URL path component (via `parse_url($url, PHP_URL_PATH)`) for `..` sequences. However, the downstream function `try_get_contents_from_local()` in `objects/functionsFile.php` uses `explode('/videos/', $url)` on the **full URL string** including the query string. An attacker can place the `/videos/../../` traversal payload in the query string to bypass the security check and read arbitrary files from the server filesystem. Commit bd11c16ec894698e54e2cdae25026c61ad1ed441 contains an updated fix.

CVE-2026-41058 High · 8.1 CWE-22 Apr 21, 2026

AVideo has an incomplete fix for CVE-2026-33293 (Path Traversal) in AVideo

WWBN AVideo is an open source video platform. In versions 29.0 and below, the incomplete fix for AVideo's CloneSite `deleteDump` parameter does not apply path traversal filtering, allowing `unlink()` of arbitrary files via `../../` sequences in the GET parameter. Commit 3c729717c26f160014a5c86b0b6accdbd613e7b2 contains an updated fix.

CVE-2026-6832 High · 8.1 CWE-22 Apr 21, 2026

Nesquena Hermes WebUI Arbitrary File Deletion via Unvalidated session_id

Hermes WebUI contains an arbitrary file deletion vulnerability in the /api/session/delete endpoint that allows authenticated attackers to delete files outside the session directory by supplying an absolute path or path traversal payload in the session_id parameter. Attackers can exploit unvalidated session identifiers to construct paths that bypass the SESSION_DIR boundary and delete writable JSON files on the host system.

CVE-2026-6829 Medium · 6.3 CWE-22 Apr 21, 2026

nesquena hermes-webui Arbitrary Workspace Directory Access

nesquena hermes-webui contains a trust-boundary failure vulnerability that allows authenticated attackers to set or change a session workspace to an arbitrary existing directory on disk by manipulating workspace path parameters in endpoints such as /api/session/new, /api/session/update, /api/chat/start, and /api/workspaces/add. Attackers can repoint a session workspace to a directory outside the intended trusted root and then use ordinary file read and write APIs to access or modify files outside the intended workspace boundary within the permissions of the hermes-webui process.

CVE-2026-40923 Medium · 5.4 CWE-22 Apr 21, 2026

Tekton Pipelines: VolumeMount path restriction bypass via missing filepath.Clean in /tekton/ check

Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. Starting in version 1.0.0 and prior to versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1, a validation bypass in the VolumeMount path restriction allows mounting volumes under restricted /tekton/ internal paths by using .. path traversal components. The restriction check uses strings.HasPrefix without filepath.Clean, so a path like /tekton/home/../results passes validation but resolves to /tekton/results at runtime. Versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1 fix the issue.

CVE-2026-40909 Medium · 6.5 CWE-22 Apr 21, 2026

WWBN AVideo has a Path Traversal in Locale Save Endpoint that Enables Arbitrary PHP File Write to Any Web-Accessible Directory (RCE)

WWBN AVideo is an open source video platform. In versions 29.0 and prior, the locale save endpoint (`locale/save.php`) constructs a file path by directly concatenating `$_POST['flag']` into the path at line 30 without any sanitization. The `$_POST['code']` parameter is then written verbatim to that path via `fwrite()` at line 40. An admin attacker (or any user who can CSRF an admin, since no CSRF token is checked and cookies use `SameSite=None`) can traverse out of the `locale/` directory and write arbitrary `.php` files to any writable location on the filesystem, achieving Remote Code Execution. Commit 57f89ffbc27d37c9d9dd727212334846e78ac21a fixes the issue.

CVE-2026-40876 High · 8.8 CWE-22 Apr 21, 2026

SFTP root escape via prefix-based path validation in goshs

goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.6, goshs contains an SFTP root escape caused by prefix-based path validation. An authenticated SFTP user can read from and write to filesystem paths outside the configured SFTP root, which breaks the intended jail boundary and can expose or modify unrelated server files. The SFTP subsystem routes requests through sftpserver/sftpserver.go into DefaultHandler.GetHandler() in sftpserver/handler.go, which forwards file operations into readFile, writeFile, listFile, and cmdFile. All of those sinks rely on sanitizePath() in sftpserver/helper.go. helper.go uses a raw string-prefix comparison, not a directory-boundary check. Because of that, if the configured root is /tmp/goshsroot, then a sibling path such as /tmp/goshsroot_evil/secret.txt incorrectly passes validation since it starts with the same byte prefix. This vulnerability is fixed in 2.0.0-beta.6.

CVE-2026-41193 Critical · 9.1 CWE-22 Apr 21, 2026

FreeScout has Zip Slip path traversal in module installation that allows arbitrary file write leading to RCE

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, FreeScout's module installation feature extracts ZIP archives without validating file paths, allowing an authenticated admin to write files arbitrarily on the server filesystem via a specially crafted ZIP. Version 1.8.215 fixes the vulnerability.

CVE-2026-40611 High · 8.8 CWE-22 Apr 21, 2026

Lego: Arbitrary File Write via Path Traversal in Webroot HTTP-01 Provider

Let's Encrypt client and ACME library written in Go (Lego). Prior to 4.34.0, the webroot HTTP-01 challenge provider in lego is vulnerable to arbitrary file write and deletion via path traversal. A malicious ACME server can supply a crafted challenge token containing ../ sequences, causing lego to write attacker-influenced content to any path writable by the lego process. This vulnerability is fixed in 4.34.0.

CVE-2026-40576 Critical · 9.4 CWE-22 Apr 21, 2026

excel-mcp-server Path Traversal (CWE-22) Enables Remote File Read and Write

excel-mcp-server is a Model Context Protocol server for Excel file manipulation. A path traversal vulnerability exists in excel-mcp-server versions up to and including 0.1.7. When running in SSE or Streamable-HTTP transport mode (the documented way to use this server remotely), an unauthenticated attacker on the network can read, write, and overwrite arbitrary files on the host filesystem by supplying crafted filepath arguments to any of the 25 exposed MCP tool handlers. The server is intended to confine file operations to a directory set by the EXCEL_FILES_PATH environment variable. The function responsible for enforcing this boundary — get_excel_path() — fails to do so due to two independent flaws: it passes absolute paths through without any check, and it joins relative paths without resolving or validating the result. Combined with zero authentication on the default network-facing transport and a default bind address of 0.0.0.0 (all interfaces), this allows trivial remote exploitation. This vulnerability is fixed in 0.1.8.

CVE-2026-40050 Critical · 9.8 CWE-22 Apr 21, 2026
