CVE-2026-57234

A flaw was found in Nokogiri, an XML and HTML library for Ruby. The NONET parse option, intended to prevent external resource fetching, was not correctly enforced in the JRuby implementation of Nokogiri::XML::Schema. This oversight could allow a specially crafted XML schema to fetch external...

CVE-2026-57234

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, the NONET parse option, which Nokogiri turns on by default for Nokogiri::XML::Schema see CVE-2020-26247, was not correctly enforced on the JRuby implementation. As a result, a schema parsed with...

CVE-2026-57235

CVE-2026-57235 affects Nokogiri (Ruby) prior to 1.19.4. The bug is in Nokogiri::XML::NodeSet#[] (and #slice) where the index check used a 32‑bit truncated copy, allowing a large negative index to pass bounds checks and be used with full width. Result: on CRuby an out‑of‑bounds read that typically...

CVE-2026-57234

Nokogiri (Ruby) prior to 1.19.4 has a vulnerability in the JRuby implementation of the NONET option for Nokogiri::XML::Schema, where default options could trigger network fetches for external resources, enabling SSRF or XXE. The issue is tied to the NONET behavior set by default for schema parsin...

CVE-2026-57234 Nokogiri: XML::Schema on JRuby allows network requests when NONET is set, bypassing CVE-2020-26247

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, the NONET parse option, which Nokogiri turns on by default for Nokogiri::XML::Schema see CVE-2020-26247, was not correctly enforced on the JRuby implementation. As a result, a schema parsed with...

GHSA-8678-W3JW-XFC2 Nokogiri: XML::Schema on JRuby allows network requests when NONET is set, bypassing CVE-2020-26247

Summary The NONET parse option, which Nokogiri turns on by default for Nokogiri::XML::Schema see CVE-2020-26247, was not correctly enforced on the JRuby implementation. As a result, a schema parsed with default options could still cause external resources to be fetched over the network, potential...

Unity Linux 20.1060e / 20.1070e Security Update: rubygem-nokogiri (UTSA-2026-016636)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016636 advisory. Nokogiri is a Rubygem providing HTML, XML, SAX, and Reader parsers with XPath and CSS selector support. In Nokogiri v1.12.4 and earlier, on JRuby only, the SAX parse...

Astra Linux – Vulnerability in JRuby

Versions of Ruby from 2.4.7, 2.5.x up to 2.5.6, and 2.6.x up to 2.6.4 allow HTTP Response Splitting. If a program using WEBrick inserts untrusted input into the response header, an attacker can exploit this to insert a newline character to split the header, thereby injecting malicious content to...

Astra Linux – Vulnerability in JRuby

Before Ruby 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an HTTP Response Splitting attack was possible. An attacker could inject a crafted key and value into an HTTP response for the WEBrick HTTP server...

Astra Linux – Vulnerability in JRuby

In Ruby, WEBrick::HTTPAuth::DigestAuth from versions 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 causes a denial-of-service attack due to a regular expression issue related to looping/backtracking. A victim must expose a WEBrick server that uses DigestAuth to the internet or a trusted...

OESA-2026-1723 rubygem-bcrypt security update

bcrypt is a sophisticated and secure hash algorithm designed by The OpenBSD project for hashing passwords. bcrypt-ruby provides a simple, humane wrapper for safely handling passwords. Security Fixes: bcrypt-ruby is a Ruby binding for the OpenBSD bcrypt password hashing algorithm. Prior to version...

CVE-2026-33306

A flaw was found in bcrypt-ruby, a Ruby binding for the OpenBSD bcrypt password hashing algorithm, specifically in its JRuby implementation. When the cost parameter is set to 31, an integer overflow occurs, causing the key-strengthening loop to execute zero iterations. This significantly weakens...

CVE-2026-33306

bcrypt-ruby is a Ruby binding for the OpenBSD bcrypt password hashing algorithm. Prior to version 3.1.22, an integer overflow in the Java BCrypt implementation for JRuby can cause zero iterations in the strengthening loop. Impacted applications must be setting the cost to 31 to see this happen. T...

CVE-2026-33306

CVE-2026-33306 affects bcrypt-ruby (JRuby Java BCrypt implementation) where a signed 32-bit integer overflow at cost=31 causes the key-strengthening loop to run zero iterations, collapsing bcrypt from 2^31 rounds to effectively constant time. This leads to weaker hashes that may be exploitable. T...
