CDN Tsunami Attack Abuses HTTP/3 Translation for Up to 350x DoS Amplification
Cybersecurity researchers have disclosed two denial-of-service DoS attacks that exploit how major content delivery networks CDNs convert client-facing HTTP/3 traffic into HTTP/1.1 requests to the websites they front, amplifying a low-bandwidth request stream by up to 350x against the origin serve...
CVE-2026-75936 Memory-amplification denial of service via GZIP decompression bomb in Amazon ion-java
Improper handling of highly compressed data in the GZIP auto-decompression handler in Amazon ion-java before 1.12.0 might allow remote actors to cause a denial of service via a crafted compressed Ion document that expands to an arbitrarily large size upon decompression. To remediate this issue,...

CVE-2026-75936
Amazon ion-java before 1.12.0 is vulnerable to a memory-amplification denial of service in its GZIP auto-decompression handler . A remote attacker can supply a crafted compressed Ion document that expands to an arbitrarily large size upon decompression, exhausting memory and causing a DoS. The vu...
CVE-2026-75935 Memory-amplification denial of service via declared-length preallocation in Amazon ion-java
Uncontrolled memory allocation in the binary Ion stream cursor in Amazon ion-java before 1.12.0 might allow remote actors to cause a denial of service via a crafted Ion binary document containing a declared-length field that causes excessive heap preallocation. To remediate this issue, users shou...
CVE-2026-75935
Amazon ion-java before 1.12.0 has uncontrolled heap preallocation in its binary Ion stream cursor. A crafted binary Ion document with a malicious declared-length field triggers excessive memory allocation, enabling remote denial of service. CVSS 7.5 HIGH; no in-the-wild exploitation reported. Upg...

CVE-2026-19671 Improper handling of highly compressed data (data amplification) in CISA Malcolm
Malcolm's upload-processing pipeline scripts/safe-extract.py enforces entry-count, nesting-depth, and total-uncompressed-byte limits when extracting container archives zip/tar/rar/7z via libarchive, but those limits are not applied when the uploaded file is a single-stream compressed format .gz,...
CVE-2026-19671
Malcolm's safe-extract.py enforces decompression limits only on container archives (zip/tar/rar/7z) but not on single-stream formats (.gz/.xz/.lzma/.lz). An authenticated user can upload a small gzip bomb that decompresses unboundedly, exhausting the shared Docker volume used by OpenSearch, Logst...
