aiosend: Deserialization of request body before signature verification (Pre-auth DoS) in webhook handler

Vulnerability Description In aiosend/webhook/base.py, the WebhookHandler.feedupdate method performs full deserialization of the incoming JSON via Pydantic before verifying the HMAC signature. Anyone can send a request with an arbitrary body — the server will parse it, spend CPU and memory, and on...

CVE-2026-31842 Tinyproxy HTTP request parsing desynchronization via case-sensitive Transfer-Encoding handling

Tinyproxy through 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive comparison of the Transfer-Encoding header in src/reqs.c. The ischunkedtransfer function uses strcmp to compare the header value against "chunked", even though RFC 7230 specifies that...

Sigstore Timestamp Authority is a service for issuing RFC 3161 timestamps. Prior to 2.0.3, Function api.ParseJSONRequest currently splits via a call to strings.Split an optionally-provided OID which is untrusted data on periods. Similarly, function api.getContentType splits the Content-Type heade...

GHSA-3RG7-WF37-54RM Symfony's incorrect parsing of PATH_INFO can lead to limited authorization bypass

Description The Request class improperly interprets some PATHINFO in a way that leads to representing some URLs with a path that doesn't start with a /. This can allow bypassing some access control rules that are built with this /-prefix assumption. Resolution The Request class now ensures that U...

GHSA-6XW4-3V39-52MM Rack is vulnerable to a memory-exhaustion DoS through unbounded URL-encoded body parsing

Summary Rack::RequestPOST reads the entire request body into memory for Content-Type: application/x-www-form-urlencoded, calling rack.input.readnil without enforcing a length or cap. Large request bodies can therefore be buffered completely into process memory before parsing, leading to denial of...
