CVE-2026-56285 Nitter - Server-Side Request Forgery in /video Media Proxy Endpoint

Nitter's /video media proxy endpoint fails to validate target URLs against Twitter/X domains and uses a hardcoded default HMAC key, allowing unauthenticated attackers to compute valid HMACs for arbitrary URLs. Attackers can retrieve HTTP responses from any host reachable by the server, including...

CVE-2026-13676 fast-uri vulnerable to host confusion via failed IDN canonicalization

fast-uri versions 2.3.1 through 3.1.2 and 4.0.0 fail to canonicalize Unicode IDN hostnames for HTTP-family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize and equal still return...

urllib3: urllib3: Information disclosure via cross-origin redirects forwarding sensitive headers

A flaw was found in urllib3, an HTTP client library for Python. When using the low-level API via ProxyManager.connectionfromurl.urlopen with assertsamehost=False, cross-origin redirects can still forward sensitive headers. This could allow a remote attacker to gain unauthorized access to sensitiv...

PYSEC-2026-388 LiteLLM: Authentication Bypass via Host Header Injection

Impact A Host-header parsing flaw in the LiteLLM proxy could, under specific conditions, allow unauthenticated access to protected management routes. The auth layer derived the effective route from request.url.path in litellm/proxy/auth/authutils.py::getrequestroute, which Starlette reconstructs...

PYSEC-2026-577 rok Python ProxyShare can be used as an SSRF proxy through absolute URL paths

Summary Alice exposes a Python SDK ProxyShare with a fixed target URL. Bob sends a request to the share with an absolute URL in the path. The Flask handler passes that path to urllib.parse.urljoin, which replaces Alice's configured target host with Bob's host and returns the server-side response ...

LiteLLM has SQL Injection in Proxy API key verification

ImpactA database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter. An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route for example POST /chat/completions an...

PYSEC-2026-365 TigerVNC accessible via the network and not just via a UNIX socket as intended

Summary jupyter-remote-desktop-proxy was meant to rely on UNIX sockets readable only by the current user since version 3.0.0, but when used with TigerVNC, the VNC server started by jupyter-remote-desktop-proxy were still accessible via the network. This vulnerability does not affect users having...

PYSEC-2026-348 h11 accepts some malformed Chunked-Encoding bodies

Impact A leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions.
