Hugo: XSS via unescaped code-fence language in default code block renderer

Hugo's default code-block renderer wrote the Markdown code-fence language / info-string into the wrapper without HTML escaping. A fence info-string containing a quote and a payload breaks out of the attribute and injects a live script element. This is not an issue if you fully trust every file...

OpenZeppelin Contracts Wizard: Line terminators in info.securityContact / info.license can inject lines into generated source

Summary The Contracts Wizard generators printed info.securityContact and info.license verbatim into a single-line comment of the generated Solidity, Cairo, Stellar/Soroban, and Stylus source without rejecting line terminators. A newline \n or \r\n in either field ends the comment, so the text aft...

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

Summary 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::Attrvalue= could free the underlying native child node while the wrapper remained...

Nokogiri: Possible Use-After-Free in XInclude Processing

Summary XInclude substitution performed by Nokogiri::XML::Nodedoxinclude replaced each in place, freeing the include node along with its children such as and its descendants and any namespaces declared on them. If an application had already exposed one of those nodes or namespaces to Ruby, the...

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

Summary 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 co...

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

Summary Nokogiri::XML::Documentroot= 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. Nokogiri...

Nokogiri: Possible Out-of-Bounds Read in `Nokogiri::XML::NodeSet#[]`

Summary Nokogiri::XML::NodeSet and its alias slice checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then be used at full width, reading outside the node set's storage. On CRuby this is an...

Nokogiri: Null Pointer Dereference calling methods on uninitialized wrapper classes

Summary Nokogiri contains a bug when calling certain methods on allocated-but-uninitialized native wrapper classes that inherit from Nokogiri::XML::Node. This caused a NULL pointer dereference that could crash the process. Nokogiri 1.19.4 checks for missing native data pointers and raises a...

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...

Nokogiri: Possible Use-After-Free when `Nokogiri::XML::Document#encoding=` raises an exception

Summary Calling Documentencoding= with an invalid encoding e.g., a non-string, or a string containing a null byte raises an exception, but only after freeing the document's current encoding string without replacing it. The document is left referencing freed memory, so the next call to...
