Rails: Active Support: Active Support: Denial of Service via large scientific notation strings

A flaw was found in Active Support, a toolkit of support libraries for Ruby on Rails. A remote attacker can exploit this vulnerability by providing specially crafted strings containing scientific notation e.g., "1e10000" to number helpers. This input causes the BigDecimal component to expand into...

CVE-2026-33176

Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation e.g. 1e10000, which BigDecimal expands into extremely large...

CVE-2026-33176 Rails Active Support has a possible DoS vulnerability in its number helpers

Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation e.g. 1e10000, which BigDecimal expands into extremely large...

CVE-2026-33176

The connected advisory GHSA-2J26-FRM8-CMJ9 confirms a DoS in Rails Active Support number helpers: parsing strings with scientific notation (e.g., 1e10000) can expand to huge decimals, causing excessive memory and CPU usage. This is triggered during number formatting and may lead to DoS. Fixed rel...

GHSA-CGWF-W82Q-5JRR Apache Commons Compress denial of service vulnerability

Improper Input Validation, Uncontrolled Resource Consumption vulnerability in Apache Commons Compress in TAR parsing.This issue affects Apache Commons Compress: from 1.22 before 1.24.0. Users are recommended to upgrade to version 1.24.0, which fixes the issue. A third party can create a malformed...

GHSA-CRQG-JRPJ-FC84 Apache Johnzon Deserialization of Untrusted Data vulnerability

A malicious attacker can craft up some JSON input that uses large numbers numbers such as 1e20000000 that Apache Johnzon will deserialize into BigDecimal and maybe use numbers too large which may result in a slow conversion Denial of service risk. Apache Johnzon 1.2.21 mitigates this by setting a...
