#450 Bump nokogiri from 1.19.2 to 1.19.4 in /docs

Sourced from nokogiri's releases.

v1.19.4 / 2026-06-18

Security

• [CRuby] (Low) Fixed a possible invalid memory read when XML::Node#initialize_copy_with_args is called with an argument that is not a Node. See GHSA-g9g8-vgvw-g3vf for more information.
• [CRuby] (Low) Fixed a possible use-after-free when an XML::XPathContext is used after its source document has been garbage collected. See GHSA-p67v-3w7g-wjg7 for more information.
• [CRuby] (Low) Fixed a possible use-after-free during XInclude processing via Node#do_xinclude. See GHSA-wfpw-mmfh-qq69 for more information.
• [CRuby] (Low) Fixed a possible use-after-free when Document#root= is assigned a non-element node. See GHSA-wjv4-x9w8-wm3h for more information.
• [CRuby] (Low) Fixed a possible use-after-free when setting an attribute value via XML::Attr#value= or #content=. See GHSA-phwj-rprq-35pp for more information.
• [CRuby] (Low) Fixed a null pointer dereference when methods are called on uninitialized wrapper objects (e.g. via allocate); these now raise instead of crashing the process. See GHSA-9cv2-cfxc-v4v2 for more information.
• [CRuby] (Low) Fixed a possible use-after-free when Document#encoding= raises an exception. See GHSA-5v8h-3h3q-446p for more information.
• [CRuby] (Medium) Fixed an out-of-bounds read in XML::NodeSet#[] (alias #slice) when given a large negative index. See GHSA-5prr-v3j2-97mh for more information.
• [JRuby] (Low) XML::Schema now enforces the NONET parse option, which Nokogiri enables by default. It was not enforced on JRuby, so a schema parsed with default options could still fetch external resources over the network, potentially enabling SSRF or XXE attacks and bypassing the mitigation for CVE-2020-26247. See GHSA-8678-w3jw-xfc2 for more information.
