CVE-2026-79772 (GCVE-0-2026-79772)

Vulnerability from nvd – Published: 2026-08-25 15:16 – Updated: 2026-08-28 22:24

Title

Nokogiri before 1.19.1 Unchecked Return Value canonicalize

Summary

Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.

CVE-2026-79771 (GCVE-0-2026-79771)

Vulnerability from nvd – Published: 2026-08-25 15:16 – Updated: 2026-08-25 17:44

Title

Nokogiri before 1.19.3 Memory Leak via XSLT Transform

Summary

Nokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.

CVE-2026-79770 (GCVE-0-2026-79770)

Vulnerability from nvd – Published: 2026-08-25 15:16 – Updated: 2026-08-25 16:10

Title

Nokogiri before 1.19.3 ReDoS via CSS selector tokenizer

Summary

Nokogiri versions before 1.19.3 contain regular expression denial of service vulnerabilities in the CSS selector tokenizer affecting string-literal and identifier tokenization. Attackers can inject adversarial CSS selectors into methods like Node#css, Node#at_css, and Searchable#search to cause exponential regex backtracking and denial of service.

Title

Nokogiri: Possible Use-After-Free in XInclude Processing

Summary

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, XInclude substitution performed by Nokogiri::XML::Node#do_xinclude replaced each <xi:include> in place, freeing the include node along with its children (such as <xi:fallback> and its descendants) and any namespaces declared on them. If an application had already exposed one of those nodes or namespaces to Ruby, the corresponding Ruby object was left pointing at freed memory. Using the object could result in invalid reads or writes to memory. This vulnerability is fixed in 1.19.4.

Severity

2.2 (Low)

Title

Nokogiri: Possible Use-After-Free when directly using `NokogirI::XML::XPathContext` beyond document lifetime

Summary

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::XPathContext did not keep its source document alive for garbage collection. If an XPathContext outlived its document and the document was collected, evaluating an XPath expression could read invalid memory and potentially segfault. This is only reachable when application code constructs an XPathContext directly and lets the document become unreachable while continuing to use the context. The normal Document#xpath, #css, and related search methods are not affected, and it is not triggerable by malicious document input. This vulnerability is fixed in 1.19.4.

Severity

1.7 (Low)

CVE-2026-57436 (GCVE-0-2026-57436)

Vulnerability from nvd – Published: 2026-06-25 14:33 – Updated: 2026-06-25 23:27

Title

Nokogiri: Possible Use-After-Free when setting `Document#root=` to an invalid node type

Summary

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::Document#root= validated only that the new root was a Nokogiri::XML::Node, allowing a DTD node to be set as the document root. The result is a heap use-after-free during garbage collection or finalization, leading to an invalid memory read or potentially a segfault. This vulnerability is fixed in 1.19.4.

Severity

1.7 (Low)

CVE-2026-57435 (GCVE-0-2026-57435)

Vulnerability from nvd – Published: 2026-06-25 14:32 – Updated: 2026-06-25 14:53

Title

Nokogiri: Possible Use-After-Free when setting an attribute value via `Nokogiri::XML::Attr#value=` or `#content=`

Summary

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri’s CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an XML attribute. If Ruby code had already accessed an attribute child node, Nokogiri::XML::Attr#value= could free the underlying native child node while the wrapper remained reachable through the document node cache. A later use of the freed child node or a Ruby GC mark could dereference an invalid pointer, causing an invalid read and a possible segfault. This vulnerability is fixed in 1.19.4.

Severity

1.7 (Low)

CVE-2026-79772 (GCVE-0-2026-79772)

Vulnerability from cvelistv5 – Published: 2026-08-25 15:16 – Updated: 2026-08-28 22:24

Title

Nokogiri before 1.19.1 Unchecked Return Value canonicalize

Summary

Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.

CVE-2026-79771 (GCVE-0-2026-79771)

Vulnerability from cvelistv5 – Published: 2026-08-25 15:16 – Updated: 2026-08-25 17:44

Title

Nokogiri before 1.19.3 Memory Leak via XSLT Transform

Summary

Nokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.

CVE-2026-79770 (GCVE-0-2026-79770)

Title

Nokogiri before 1.19.3 ReDoS via CSS selector tokenizer

Summary

Nokogiri versions before 1.19.3 contain regular expression denial of service vulnerabilities in the CSS selector tokenizer affecting string-literal and identifier tokenization. Attackers can inject adversarial CSS selectors into methods like Node#css, Node#at_css, and Searchable#search to cause exponential regex backtracking and denial of service.
