CVE-2026-48044

Summary: CVE-2026-48044 affects Envoy’s zstd decompressor (ZstdDecompressorImpl). From 1.23.0 through 1.35.11, 1.36.7, 1.37.3, and 1.38.1, specially crafted, highly compressed zstd payloads can trigger massive memory allocation when decompression is enabled, potentially causing memory exhaustion ...

EUVD-2026-39820

Envoy is an open source edge and service proxy designed for cloud-native applications. From 1.23.0 until 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability has been identified in Envoy's zstd decompressor implementation ZstdDecompressorImpl. When zstd decompression is enabled, processing a...

GHSA-XV9W-7V6Q-HPJH fluent-plugin-s3 Vulnerable to Denial of Service (DoS) via Decompression Bomb in `in_s3`

The fluent-plugin-s3 plugin specifically the ins3 input plugin supports reading and decompressing heavily compressed files such as gzip, lzma2, and lzop from Amazon S3. It was discovered that the plugin read the entire decompressed payload into memory at once without enforcing a strict size limit...

GHSA-J9CW-HWQF-85W7 Fluentd is Vulnerable to Denial of Service (DoS) via Gzip Decompression Bomb in `in_http` and `in_forward`

Fluentd's inhttp and inforward plugins support receiving gzip-compressed data. While Fluentd correctly enforces size limits on the incoming compressed payloads e.g., via bodysizelimit or chunksizelimit, it was discovered that there is no limit enforced on the size of the decompressed data. If a...

PT-2026-60346

Name of the Vulnerable Software and Affected Versions 7-Zip versions prior to 26.02 Description A heap-based buffer overflow exists in the XZ decoder component when processing specially crafted XZ chunked data. The issue occurs within the MixCoder Code function in the XzDec.c file, where the...

PT-2026-53004

Name of the Vulnerable Software and Affected Versions Fluentd versions prior to 1.19.3 Description The in http and in forward plugins support gzip-compressed data but only enforce size limits on the compressed payloads via settings like body size limit and chunk size limit. Because no limit is...

Rekor has an OOM Condition due to Unbounded gzip Decompression in Alpine APK Parsing Logic

Description 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. The existing maxapkmetadatasize check default 1MB is only applied to individual tar entry...

CVE-2026-54250 K3s: ZIP Archive Path Traversal Vulnerability in etcd Snapshot Decompression

K3s is a fully conformant production-ready Kubernetes distribution. Prior to 1.35.3+k3s1, 1.34.6+k3s1, v1.33.10+k3s1, a path traversal vulnerability exists in K3s's etcd snapshot decompression functionality. Zip files containing archive members with maliciously crafted names can be written to...

CVE-2026-54250

CVE-2026-54250 affects K3s by a ZIP archive path traversal in the etcd snapshot decompression. Before versions 1.35.3+k3s1, 1.34.6+k3s1, and v1.33.10+k3s1, a crafted ZIP member can be written to arbitrary filesystem locations when restoring an etcd snapshot, due to the decompression process. Impa...

CVE-2026-54278

A flaw was found in aiohttp, an asynchronous HTTP client/server framework. An attacker could send a specially crafted compressed request body that, during cleanup, would be decompressed into memory in one large chunk. This could potentially lead to a Denial of Service DoS condition, where the...

CVE-2026-54448

CVE-2026-54448 affects Trivy. Prior to version 0.71.0, its Helm chart scanner uses a custom tar unpacker that reads each archive entry with io.ReadAll(tr) without a size limit, enabling a malicious .tgz to decompress to gigabytes and trigger the OS OOM killer. This could cause the Trivy process t...

CVE-2026-54448

Trivy is a security scanner. Prior to 0.71.0, when Trivy scans a Helm chart archive .tgz, its custom tar unpacker reads each entry with io.ReadAlltr and no size limit. An attacker who can place a malicious .tgz file in the scanned path can craft a small compressed archive that decompresses to...

perl-IO-Compress: perl-IO-Compress: Arbitrary code execution via attacker-controlled output glob

A flaw was found in perl-IO-Compress, a component used for data compression and decompression. A remote attacker could exploit this vulnerability by crafting a malicious input, specifically an output glob, that bypasses the intended security measures. This could lead to the execution of...

CVE-2026-53272

The CVE-2026-53272 issue affects the Linux kernel’s erofs subsystem. A use-after-free on sbi->sync_decompress can occur when z_erofs_endio() queues z_erofs_decompressqueue_work() and, after folios are unlocked, the unmount path completes with sbi freed before sbi->sync_decompress is accesse...
