PYSEC-2026-4182 Zapros: Streaming decoders ignored the requested chunk size, allowing a single compressed response chunk to allocate unbounded memory (decompression bomb)

Impact Denial of service via memory exhaustion. Affects all callers who streamed compressed responses relying on the chunk size — explicit iterbyteschunksize=... or the default — to bound memory. The decoder ignored that bound, so a chunk could be far larger than requested and a single compressed...

CVE-2026-103262

A flaw was found in Tornado. A remote malicious server can cause a Denial of Service DoS when an application using the CurlAsyncHTTPClient component fetches an untrusted web address. Because the client fails to enforce limits on incoming response sizes, the attacker can return a small, highly...
