CVE-2026-59200 Pillow: Decompression Bomb DoS via PdfParser.PdfStream.decode()

Pillow is a Python imaging library. From 5.1.0 until 12.3.0, PdfParser.PdfStream.decode in PIL/PdfParser.py calls zlib.decompress with bufsize set to the PDF stream Length field without bounding the decompressed output size, allowing a crafted FlateDecode PDF stream to exhaust memory from a small...

PYSEC-2026-2972 py7zr: Decompression bomb (zip bomb) denial of service via unchecked extraction size

py7zr's Worker.decompress extracts archive entries without tracking total decompressed size. A crafted .7z file can exhaust disk or memory before the extraction completes. Measured: 15.6 KB archive → 100 MB output 6,556:1 ratio. Proof of concept: python import py7zr, tempfile, os create bomb:...

PYSEC-2026-2912 PraisonAI Vulnerable to Decompression Bomb DoS via Recipe Bundle Extraction Without Size Limits

Summary The safeextractall function in PraisonAI's recipe registry validates archive members against path traversal attacks but performs no checks on individual member sizes, cumulative extracted size, or member count before calling tar.extractall.

CVE-2026-44160 Fluentd: Denial of Service (DoS) via Gzip Decompression Bomb in `in_http` and `in_forward`

Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS, Hadoop and so on. Prior to 1.19.3, Fluentd's inhttp and inforward plugins support gzip-compressed data but enforce limits only on compressed payloads through settings such as bodysizelimit and...

CVE-2026-55195

CVE-2026-55195 affects the py7zr Python library (pre-1.1.3) where Worker.decompress() did not track the total decompressed size. A crafted 7z archive (e.g., 15.6 KB) could expand to ~100 MB, causing disk and memory exhaustion during extraction. This is a denial-of-service risk. The issue is fixed...

CVE-2026-55195 py7zr: Decompression bomb (zip bomb) denial of service via unchecked extraction size

py7zr is a Python-based library and utility to support 7zip archive compression, decompression, encryption and decryption. Prior to 1.1.3, py7zr's Worker.decompress extracted archive entries without tracking total decompressed size, allowing a crafted .7z file such as a 15.6 KB archive that expan...

CVE-2026-59803 rpcx - Denial of Service via Gzip Decompression Bomb in Wire Protocol

rpcx through 1.9.3, fixed in commit 047aec1, contains a denial-of-service vulnerability in protocol.Message.Decode protocol/message.go. When a message has the compression flag set, the payload is gzip-decompressed via util.Unzip with no limit on the decompressed output size. The only built-in siz...

BIT-PILLOW-2026-55380 Pillow GdImageFile decompression bomb protection bypass

Pillow is a Python imaging library. Prior to 12.3.0, PIL/GdImageFile.py GdImageFile.open read image dimensions from the GD 2.x header and stored them in self.size without calling Image.decompressionbombcheck, allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This iss...
