PSF-2026-18

Use-after-free UAF was possible in the lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile when a memory allocation fails with a MemoryError and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling...

undici: undici: Denial of Service via unbounded memory consumption during WebSocket permessage-deflate decompression

A flaw was found in undici. A remote attacker can exploit this vulnerability by sending a specially crafted compressed frame, known as a "decompression bomb," during permessage-deflate decompression. The undici WebSocket client does not properly limit the size of decompressed data, leading to...

PT-2026-32487

Name of the Vulnerable Software and Affected Versions Python affected versions not specified Description A use-after-free flaw exists in the decompression modules of Python, specifically within lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile. This issue occurs when a program re-uses...

SUSE CVE-2026-1526

The undici WebSocket client is vulnerable to a denial-of-service attack via unbounded memory consumption during permessage-deflate decompression. When a WebSocket connection negotiates the permessage-deflate extension, the client decompresses incoming compressed frames without enforcing any limit...

urllib3: urllib3: Denial of Service due to excessive HTTP response decompression

A flaw was found in urllib3, an HTTP client library for Python. This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response,...

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. An attacker can publish a malicious recipe bundl...

Security Bulletin: Decompression Bomb Vulnerability in urllib3 affects watsonx.data

Summary urllib3 versions ≥1.24 and 2.6.0 are vulnerable to unbounded decompression chains. A malicious server can trigger excessive CPU and memory usage by sending many nested compression steps. The issue is fixed in version 2.6.0. This can affect watsonx.data. Vulnerability Details...

Security Bulletin: Decompression Bomb Vulnerability in Undic, affects watsonx.data

Summary Undici versions prior to 7.18.0 and 6.23.0 are vulnerable to unbounded decompression chains. Malicious servers can exploit this to trigger high CPU usage and excessive memory allocation due to thousands of compression steps. This can affect watsonx.data. Vulnerability Details...

PraisonAI 路径遍历漏洞

PraisonAI is a low-code multi-agent collaboration framework developed by Mervin Praison. Versions of PraisonAI prior to 4.5.128 contained a path traversal vulnerability. This vulnerability occurred because the recipe CLI did not validate paths when decompressing.praison archives, potentially...
