brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

CVE-2026-67422

CVE-2026-67422 affects pymdown-extensions up to version 11.0, where four inline processors—caret, tilde, betterem, and magiclink—use regex patterns whose groups can partition delimiter runs in exponentially many ways. This causes catastrophic backtracking and unbounded CPU usage when rendering a ...

Linux Distros Unpatched Vulnerability : CVE-2026-53504

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Thumbor is an open-source photo thumbnail service by globo.com. Prior to 7.8.0, the convolution filter regular expression performs exponential backtracking on...

python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

SummaryWhen resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an exponential blowup. Although the limitation that the chain depth cannot exceed a specified maximum depth prevents...
