CVE-2026-42006

An attacker can cause uncontrolled memory usage with excessive bracing over IMAP. The fix in CVE-2026-27857 was incomplete, only blocking one way of doing this, so there was still another way left open. In particular, the fix was for closing braces, but you could still use open braces to bypass t...

BIT-LIBPYTHON-2025-13836 Excessive read buffering DoS in http.client

When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially causing OOM or other DoS...

urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API

Impact urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or...

Improper Handling of Highly Compressed Data (Data Amplification)

Overview exifreader is a Library that parses Exif metadata in images. Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification due to decompressing PNG zTXt metadata without enforcing a built-in maximum decompressed output size. When...

brace-expansion: brace-expansion: Denial of Service due to excessive memory allocation when expanding large numeric ranges

A flaw was found in the brace-expansion library. This vulnerability allows an attacker to cause a Denial of Service DoS by providing a large numeric range for expansion. The library allocates excessive memory to generate all intermediate elements before applying the maximum limit, leading to high...
