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...
GHSA-P67V-3W7G-WJG7 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.

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...
GHSA-5PRR-V3J2-97MH 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...
XML External Entity (XXE) Injection
Overview nokogiri is a gem for parsing HTML, XML, SAX, and Reader. Affected versions of this package are vulnerable to XML External Entity XXE Injection in the Nokogiri::XML::Schema when the NONET parse option is not correctly enforced on JRuby. An attacker can access external network resources b...

YARD is a documentation generation tool for the Ruby programming language. Prior to version 0.9.44, YARD's static cache lookup reads a request path before the router's path cleanup runs. When a server is configured with a document root, a traversal path such as /../yard-cache-secret.html is joine...
Concurrent Ruby - `AtomicReference#update` livelocks when the stored value is `Float::NAN`
Summary Concurrent::AtomicReferenceupdate can enter a permanent busy retry loop when the current value is Float::NAN. The issue is caused by the interaction between: - AtomicReferenceupdate, which retries until compareandsetoldvalue, newvalue succeeds. - Numeric compareandset, which checks old ==...
Oj - intern.c form_attr (uninitialized stack read)
Summary Oj.load in :object mode reads uninitialized stack memory and, for long keys, reads out of bounds when parsing a JSON object whose key is 254 bytes or longer. The interned bytes can surface to the caller, disclosing process stack memory. Impact Information disclosure of process stack memor...
Oj - Use-After-Free in Oj::Parser SAJ Callback via Input Mutation
Summary Oj::Parserparse is vulnerable to a heap use-after-free when a SAJ/SAJ2 callback mutates the input JSON string during parsing. The C engine holds a raw const byte pointer into the Ruby string's internal buffer. If a callback e.g. hashstart resizes the string — for example by calling...
