Summary motionEye v0.43.1 latest stable is vulnerable to path traversal in the picture and movie API endpoints, like /picture/id/preview/filename. Neither the API handlers, nor the mediafiles.py functions like getmediapreview check for .. sequences in the filename parameter, except getmediaconten...

PYSEC-2026-2860 pdfkit: Path traversal in from_string

In JazzCore python-pdfkit 1.0.0, the fromstring method enables the execution of JavaScript code within the context of the server application and the exfiltration of local files...

PYSEC-2026-2392 BBOT: Path traversal (Zip-Slip) in unarchive module - incomplete fix for CVE-2025-10284

The unarchive internal module's archive extraction commands perform no code-level validation on extracted file paths, relying entirely on the behavior of external tools e.g. GNU tar which varies by platform. While CVE-2025-10284 addressed git-specific RCE vectors, the underlying archive extractio...

PYSEC-2026-2393 BBOT: Arbitrary File Write in postman_download Module

The postmandownload module uses the workspace name field from the Postman API to construct the local directory path without sanitization. If a malicious workspace has a name containing path traversal characters, pathlib resolves the path outside the intended output directory, allowing an attacker...

PYSEC-2026-2736 Open WebUI: Sibling-Prefix Path Traversal via /cache/{path}

Summary A path traversal vulnerability exists in open-webui's cache file serving endpoint that allows any authenticated user to read files from sibling directories outside the intended cache directory, by exploiting an incomplete startswith containment check that lacks a trailing path separator...

PYSEC-2026-2751 Open WebUI: Path traversal / SSRF in terminal server proxy via encoded path traversal

Summary The terminal-server reverse proxy in backend/openwebui/routers/terminals.py does not fully confine the user-controlled path segment before forwarding it to an admin-configured terminal server. An authenticated user who has been granted access to a terminal server can craft path values...

PYSEC-2026-2566 Langflow: Path Traversal in Knowledge Bases API via Creation Endpoint

Summary Langflow is vulnerable to Path Traversal in the Knowledge Bases API POST /api/v1/knowledgebases. This occurs because user-supplied knowledge base names are used directly to create file paths without proper sanitization or containment checks. An authenticated attacker can exploit this flaw...

PYSEC-2026-2556 LangChain: Path traversal and sandbox escape in LangChain file-search middleware and loaders

Summary Several LangChain components that resolve filesystem paths or expand search patterns do not consistently confine the resolved path to the intended root directory. Affected behaviors include: a file-search agent middleware that validates a starting directory but not the search pattern or t...

PDM wheel installation leads to Path Traversal via overridden write_to_fs

InstallDestination.writetofs in src/pdm/installers/installers.py overrides the base class to add symlink/hardlink support but replaces the safe pathwithdestdir which validates via Path.resolve + isrelativeto with a bare os.path.join that performs no path validation. A malicious wheel with travers...

PYSEC-2026-2861 PDM wheel installation leads to Path Traversal via overridden write_to_fs

InstallDestination.writetofs in src/pdm/installers/installers.py overrides the base class to add symlink/hardlink support but replaces the safe pathwithdestdir which validates via Path.resolve + isrelativeto with a bare os.path.join that performs no path validation. A malicious wheel with travers...

PYSEC-2026-3428 WsgiDAV encoded dot segments can escape filesystem share roots

Impact WsgiDAV 4.3.3 can allow a WebDAV request path containing an encoded parent-directory segment to escape the configured filesystem share root in a specific path layout. Patches The issue is fixed with version 4.3.4. Preconditions The practical impact depends on the deployment. The deployment...

PYSEC-2026-2532 Jupyter Server vulnerable to Path Traversal via incorrect root directory boundary check in _get_os_path()

A path traversal vulnerability exists in jupyter-server version 2.17.0 due to an incorrect root directory boundary check in the getospath function within jupyterserver/services/contents/fileio.py. The check uses startswithroot without appending a trailing path separator, allowing sibling...

PYSEC-2026-3429 xiaomusic contains an unauthenticated path traversal vulnerability

xiaomusic v0.5.7 contains an unauthenticated path traversal vulnerability in the GET /music/filepath:path endpoint that allows unauthenticated attackers to read arbitrary files outside the intended music directory by exploiting an incomplete path prefix check. Attackers can request files from...

PYSEC-2026-3065 Shamefile has an arbitrary file read via shamefile.yaml in shame next

Impact A path traversal vulnerability in shame next allows an attacker-controlled shamefile.yaml to disclose contents of files outside the repository, one line at a time, to the terminal of a user who runs the command. See patch commit for technical details. Patches Fixed in 0.1.7. Upgrade to...

PYSEC-2026-2423 compliance-trestle - jinja has an Arbitrary File Write via Path Traversal

Relevant Products/Components: trestle/core/commands/author/jinja.py trestle author jinja --- Detailed Description: The -o/--output argument in trestle author jinja allows writing files outside the intended workspace. The application does not properly validate: ../ ..\ absolute paths This allows...

PYSEC-2026-2426 compliance-trestle Profile Import has an Arbitrary File Read via trestle:// URI and Relative Path Traversal

Summary The compliance-trestle library's profile import mechanism resolves trestle:// URIs and relative file paths by joining them with trestleroot and calling .resolve, but performs no boundary check to ensure the resolved path stays within the trestle workspace. An attacker can craft a maliciou...

PYSEC-2026-2427 compliance-trestle Vulnerable to SSRF in Remote Fetching Subsystem

A source code audit led to the discovery of three significant security vulnerabilities in the trestle/core/remote/cache.py module. Finding 1 Critical: SSRF CWE-918 The HTTPSFetcher.dofetch method passes a user-supplied URL directly to requests.get without validation. This allows an attacker to...

PYSEC-2026-2424 compliance-trestle Remote Fetching Mechanism has an Arbitrary File Write via Cache Path Traversal

Summary The compliance-trestle library's remote fetching cache mechanism HTTPSFetcher and SFTPFetcher constructs the local cache file path from the URL path component without sanitizing path traversal sequences ../. When a remote OSCAL profile references a URL with traversal in its path, the HTTP...

PYSEC-2026-3081 Taipy contains a path traversal vulnerability

Taipy 4.1.1, fixed in commit 129fd40, contains a path traversal vulnerability in the ElementLibrary.getresource method in taipy/gui/extension/library.py that allows unauthenticated attackers to escape the intended module directory by exploiting an incomplete path containment check using...

PYSEC-2026-2384 AsyncSSH `AuthorizedKeysFile %u` path traversal allows attacker-selected authorized keys to authenticate a traversal username

Summary AsyncSSH 2.22.0 expands the OpenSSH-compatible AuthorizedKeysFile %u token with the raw SSH username during pre-authentication server config reload. A server configured with a documented per-user key pattern such as AuthorizedKeysFile authorizedkeys/%u can be made to read an authorized-ke...
