Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification in the decompression. An attacker can exhaust system resources and render the service unavailable by sending specially crafted, highly compressed data payloads. Remediation...

CVE-2026-53716

A flaw was found in Envoy Gateway. A remote attacker, by providing a specially crafted compressed WebAssembly Wasm payload through a tenant-controlled URL, can exploit a vulnerability where the system decompresses the gzip file without limiting the output size. This can lead to an uncontrolled...

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

ImpactDenial 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...

PYSEC-2026-4181 Zapros has an Unbounded Content-Encoding decompression chain that allows denial of service

Impact Who is impacted: - Any application using Zapros to make HTTP requests to untrusted servers - Applications that follow redirects to attacker-controlled hosts Attack vector: - A malicious HTTP server returns a response with many chained content encodings. When the client attempts to decode, ...

Improper Handling of Highly Compressed Data (Data Amplification)

Overview tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification via curlhttpclient.py in CurlAsyncHTTPClient, which passes every...

AZL-105378 CVE-2026-103262 affecting package python-tornado 6.3.3-11

Tornado versions before 6.5.9 contain an unbounded memory accumulation vulnerability in CurlAsyncHTTPClient that allows remote attackers to cause denial of service by sending a compressed response. Attackers can send a gzip-encoded decompression bomb that accumulates in memory without size limits...

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...
