CVE-2026-61541 Zapros has an Unbounded Content-Encoding decompression chain that allows denial of service
Zapros, a Python HTTP client, prior to version 0.14.0 is vulnerable to denial of service when an application requests content from an untrusted server, or follows a redirect to one, because a malicious response containing an excessive number of chained Content-Encoding values causes Zapros to...
CVE-2026-61652 Zapros: Streaming decoders ignored the requested chunk size, allowing a single compressed response chunk to allocate unbounded memory (decompression bomb)
Zapros, a Python HTTP client, prior to version 0.14.0 is vulnerable to denial of service via memory exhaustion. The issue affects all callers who streamed compressed responses relying on the chunk size — explicit iterbyteschunksize=... or the default — to bound memory. The decoder ignored that...
CVE-2026-61652
Zapros , a Python HTTP client, prior to version 0.14.0 is vulnerable to denial of service via memory exhaustion . The root cause is that its streaming decoders ignored the requested chunk size (both explicit iter_bytes(chunk_size=...) and the default), allowing a single compressed response chunk ...

Security Bulletin: Impacted IBM Optim 1.2.0 by vulnerabilities in scrapy
Summary IBM Optim version 1.2.0 depends on an open-source package scrapy which is affected by a high-severity vulnerabilities. IBM Optim 2.0.0 resolves these vulnerabilities by upgrading the affected open-source dependency to a fixed version. Vulnerability Details CVEID:CVE-2025-6176 DESCRIPTION:...
netty: io.netty/netty-codec-http: io.netty/netty-codec-http2: Netty: Denial of Service via unbounded memory allocation in HTTP content decompression
A flaw was found in Netty. A remote attacker can bypass the configured decompression limit in the HttpContentDecompressor by sending a specially crafted compressed payload using Brotli br, Zstandard zstd, or Snappy content encodings. This can lead to unbounded memory allocation, resulting in an...
SoupWebsocketExtensionDeflate: libsoup: libsoup: WebSocket permessage-deflate Unbounded Decompression Remote Denial of Service
A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...
netty: io.netty/netty-codec-http: Netty: Denial of Service via SPDY header decompression amplification
A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to...
io.netty/netty-codec-http: Netty: Memory exhaustion in netty-codec-http (decompression bomb)
A flaw was found in the Netty netty-codec-http component. A remote attacker can send HTTP requests containing highly compressed data. The HTTP decoder in netty-codec-http fails to properly limit the decompression of this content, causing the system to consume excessive memory. This can lead to...
io.netty/netty-codec-http2: Netty: Denial of Service via HTTP/2 DATA frame memory leak
A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing t...
CVE-2026-77021 Missing decompression size limit in agent receiver allows memory exhaustion via push agent data
Improper handling of highly compressed data data amplification in Checkmk 2.5.0p14, 2.4.0p37, 2.3.0p51 and 2.2.0 EOL allows an attacker who controls a host registered for push mode to exhaust the memory of the agent receiver by sending a small zlib compressed payload that decompresses to an...
Security update for libheif
This update for libheif fixes the following issues: CVE-2026-84383: Heap buffer overflow in scalenearestneighbor via duplicate alpha planes from nested iden/auxl items bsc1279443. CVE-2026-84384: brotli/zlib decompression paths lack output-size limits, allowing decompression-bomb OOM/DoS...
BIT-ENVOY-GATEWAY-2026-53716 Envoy Gateway: Wasm HTTP fetch decompresses gzip without output-size limit
Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. Prior to 1.7.4 and 1.8.1, getFileFromGZ in internal/wasm/httpfetcher.go calls io.ReadAll on a gzip.Reader without limiting decompressed output when a tenant-controlled...
CVE-2026-47321 Apache MINA: Unbounded Decompression Amplification DoS in Zlib.inflate
The CompressionFilter class uses ZLib to deflate and inflate data sent and received. When we inflate incoming data, the filter does not control the resulting size, and create a buffer no matter what. Some compressed data may have a compression ration greater than 1 thousand, leading to an...
