CVE-2026-66754
Rouille 0.1.6–3.6.2 has a reachable assertion DoS in Request::remove_prefix. An unauthenticated attacker can crash the server by sending a crafted percent-encoded URL where the decoded path matches a configured prefix but the raw percent-encoded path does not, causing an assert! failure and resul...
open-webui terminal proxy path traversal guard bypass via 9x encoded traversal
AI assistance was used to help inspect the code and prepare this report. Summary The fix for GHSA-r2wg-2mcr-66rv is incomplete in v0.9.6 and current main. backend/openwebui/routers/terminals.py documents sanitizeproxypath as decoding until stable, but the implementation stops after 8 unquote...
Microsoft Kiota: Path traversal in generated plugin manifest static_template.file reference (percent-encoding bypass)
Impact Kiota generates AI plugin manifests from an OpenAPI description. When the description contains an x-ai-capabilities response semantics statictemplate or the adaptive-card extension x-ai-adaptive-card, the file reference is written into the generated manifest's...

Mistune: XSS via percent-encoded javascript URI bypass in safe_url()
Summary An XSS vulnerability in Mistune allows bypassing of safeurl protections via percent-encoded javascript URIs. Details The vulnerability exists in HTMLRenderer.safeurl in Mistune. The function is intended to block harmful URL schemes such as "javascript:" by checking the prefix of the...
CVE-2026-48760
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 6.1.0 until 6.4.41, 7.4.13, and 8.0.13, UrlSanitizer::parse rejected raw BiDi formatting characters but not percent-encoded forms and used an ASCII-only whitespace check, allowing sanitized URLs...
CVE-2026-59221
Open WebUI before 0.10.0 is affected by a path traversal guard bypass in sanitize_proxy_path (backend/open_webui/routers/terminals.py). The function decodes proxy paths only eight times, allowing a nine-times percent-encoded ../ traversal to bypass normalization and be decoded by the upstream ter...
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-2026-14181
CVE-2026-14181 affects @fastify/middie versions 9.1.0 through 9.3.2, where the URL normalization step in the standalone engine fails to sanitize malformed percent‑encoded sequences. Inputs such as incomplete escapes or truncated multibyte sequences cause the underlying decoder to throw synchronou...
EUVD-2026-40947
@fastify/middie versions 9.1.0 through 9.3.2 fail to guard the URL normalization step used by the standalone engine when incoming request paths contain malformed percent-encoded sequences. Inputs such as an incomplete percent escape or a truncated multibyte sequence cause the underlying decoder t...
