CVE-2026-33036

CVE-2026-33036 concerns the fast-xml-parser library. A bypass vulnerability in versions 4.0.0-beta.3 through 5.5.5 allows numeric character references (&#NNN;, &#xHH;) and standard XML entities to evade entity expansion limits (maxTotalExpansions, maxExpandedLength) intended to fix CVE-2026-26278...

fast-xml-parser 安全漏洞

fast-xml-parser is an open-source library developed by Natural Intelligence. It is used for quickly validating, parsing, and processing XML files without relying on C/C++-based libraries or callbacks. There are security vulnerabilities in the versions of fast-xml-parser from 4.0.0-beta.3 to 5.5.5...

CVE-2006-10003

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...

XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in stserialstack. In the case stackptr == stacksize - 1, the stack will NOT be expanded. Then the new value will be written at location ++stackptr, which equals stacksize and therefore falls just outside the allocat...
