openhole-server vulnerable to path traversal via URL-decoded request path

Summary openhole-server forwarded the URL-decoded request path r.URL.Path to tunnel clients instead of the original request-target. Percent-encoded dot-segments %2e and separators %2f were decoded to ../ and / before reaching the local service. Go's ServeMux rejects literal ../ paths, but...

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...

CVE-2026-59221

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 before 0.10.0, sanitizeproxypath in backend/openwebui/routers/terminals.py decoded proxy paths only eight times, allowing a nine-times percent-encoded ../ traversal value to pass normalization checks...

CVE-2026-45807

Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.43 and 1.3.19, several Kestra API endpoints accept a kestra:// URI from the client and pass it through StorageInterface.parentTraversalGuard before reading the underlying file from the local storage backend. The guard onl...

SiYuan is vulnerable to Directory Traversal. The vulnerability is due to improper validation of file paths in the /export endpoint, which allows an attacker to use double-encoded traversal sequences to read arbitrary files and obtain sensitive information...

GHSA-69XR-M8H6-H664 Angular SSR has Open Redirect and Request Steering via Encoded X-Forwarded-Prefix

Description A vulnerability exists in the X-Forwarded-Prefix header processing logic within Angular SSR. The internal validation mechanism fails to properly account for URL-encoded characters, specifically dots %2e%2e. This allows an attacker to bypass security filters by injecting encoded path...

GHSA-5W89-W975-HF9Q Nitro has a proxy scope bypass via percent-encoded path traversal in `routeRules`

A proxy route rule like: ts routeRules: "/api/orders/": proxy: to: "http://upstream/orders/" is intended to limit the proxy to URLs under /api/orders/. Before the patch, an attacker could bypass that scope by sending percent-encoded path traversal ..%2f in the URL, causing Nitro to forward a...
