perl-xml-parser: XML::Parser: Memory corruption via deeply nested XML files

A flaw was found in XML::Parser, a Perl module for parsing XML. This vulnerability, an off-by-one heap buffer overflow, occurs when processing an XML file with very deep element nesting. A remote attacker could exploit this by providing a specially crafted XML file, potentially leading to memory...

CVE-2026-40324

Hot Chocolate (GraphQL server) contains a vulnerability in Utf8GraphQLParser: prior to versions 12.22.7, 13.9.16, 14.3.1, and 15.1.14, the recursive descent parser has no recursion-depth limit, so deeply nested GraphQL documents (as small as ~40 KB) can trigger a StackOverflowException. This unca...

RLSA-2026:7679 Important: perl-XML-Parser security update

This module provides ways to parse XML documents. It is built on top of XML::Parser::Expat, which is a lower level interface to James Clark's expat library. Each call to one of the parsing methods creates a new instance of XML::Parser::Expat which is then used to parse the document. Expat options...

CVE-2026-1849 Mongod can run out of stack memory when expressions create deeply nested documents

MongoDB Server may experience an out-of-memory failure while evaluating expressions that produce deeply nested documents. The issue arises in recursive functions because the server does not periodically check the depth of the expression...

PT-2026-7433

Name of the Vulnerable Software and Affected Versions MongoDB Server affected versions not specified Description The MongoDB Server may encounter an out-of-memory failure when processing expressions that result in deeply nested documents. This occurs due to a lack of periodic depth checks within...
