GHSA-G4W2-6H2R-3M3W http4k: Unbounded gzip decompression in `ServerFilters.GZip` / `RequestFilters.GunZip` allowed memory-exhaustion DoS

Impact ServerFilters.GZip and RequestFilters.GunZip and the underlying Gzip functions used to decompress request bodies did not impose any cap on the decompressed size. A small malicious gzip-encoded request body on the order of kilobytes could decompress to gigabytes, exhausting the JVM heap and...

CVE-2026-48702 Rekor has an OOM Condition due to Unbounded gzip Decompression in Alpine APK Parsing Logic

Rekor is a software supply chain transparency log. Starting in version 0.3.0 and prior to version 1.5.2, the Package.Unmarshal function in pkg/types/alpine/apk.go decompresses the signature and control gzip members of an APK file into in-memory buffers without bounding the total decompressed size...

CVE-2026-48702

CVE-2026-48702 : Rekor before 1.5.2 decompresses APK signatures in Alpine APK parsing without bounding the total decompressed size, enabling a decompression bomb via gzip with extreme ratios. Attackers can trigger unbounded heap allocation during requests to unauthenticated endpoints POST /api/v1...

CVE-2026-73232

ffuf is a fast web fuzzer written in Go. Prior to 2.2.0, ffuf allows a malicious target server to cause an out-of-memory denial of service because the response size guard in pkg/runner/simple.go checks only the compressed Content-Length while io.ReadAll reads gzip, brotli, deflate, transparently...

Important: python-tornado

Issue Overview: Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.6, SimpleAsyncHTTPClient shallow-copied redirected requests and removed only the Host header, leaving Authorization, authusername, authpassword, and authmode in place when a redirect changed scheme...

CVE-2026-68981 Apache NiFi: Uncontrolled Resource Consumption through Decompression of HTTP Requests

Apache NiFi 1.5.0 through 2.10.0 support gzip-encoded HTTP requests for the application REST API using a Jersey encoding filter. The framework enforced a configurable maximum request size on the compressed payload rather than the decompressed output, allowing a malicious client to send crafted...

SUSE CVE-2026-44981

CrowdSec offers crowdsourced protection against malicious IPs. From 1.7.0 until 1.7.8, the LAPI router used gin-contrib/gzip with DefaultDecompressHandle globally in pkg/apiserver/controllers/controller.go, causing /v1/watchers and /v1/watchers/login to decompress unauthenticated gzip-compressed...
