| CVE-2024-41818 | 2 Naturalintelligence, Redhat | 4 Fast-xml-parser, Fast Xml Parser, Container Native Virtualization and 1 more | 2026-03-09 | 7.5 High |
| fast-xml-parser is an open source, pure javascript xml parser. a ReDOS exists on currency.js. This vulnerability is fixed in 4.4.1. | ||||
| CVE-2023-34104 | 2 Naturalintelligence, Redhat | 2 Fast-xml-parser, Migration Toolkit Applications | 2026-03-09 | 7.5 High |
| fast-xml-parser is an open source, pure javascript xml parser. fast-xml-parser allows special characters in entity names, which are not escaped or sanitized. Since the entity name is used for creating a regex for searching and replacing entities in the XML body, an attacker can abuse it for denial of service (DoS) attacks. By crafting an entity name that results in an intentionally bad performing regex and utilizing it in the entity replacement step of the parser, this can cause the parser to stall for an indefinite amount of time. This problem has been resolved in v4.2.4. Users are advised to upgrade. Users unable to upgrade should avoid using DOCTYPE parsing by setting the `processEntities: false` option. | ||||
| CVE-2026-26278 | 1 Naturalintelligence | 1 Fast-xml-parser | 2026-03-02 | 7.5 High |
| fast-xml-parser allows users to validate XML, parse XML to JS object, or build XML from JS object without C/C++ based libraries and no callback. In versions 4.1.3 through 5.3.5, the XML parser can be forced to do an unlimited amount of entity expansion. With a very small XML input, it’s possible to make the parser spend seconds or even minutes processing a single request, effectively freezing the application. Version 5.3.6 fixes the issue. As a workaround, avoid using DOCTYPE parsing by `processEntities: false` option. | ||||
| CVE-2026-25896 | 1 Naturalintelligence | 1 Fast-xml-parser | 2026-03-02 | 9.3 Critical |
| fast-xml-parser allows users to validate XML, parse XML to JS object, or build XML from JS object without C/C++ based libraries and no callback. From 4.1.3to before 5.3.5, a dot (.) in a DOCTYPE entity name is treated as a regex wildcard during entity replacement, allowing an attacker to shadow built-in XML entities (<, >, &, ", ') with arbitrary values. This bypasses entity encoding and leads to XSS when parsed output is rendered. This vulnerability is fixed in 5.3.5. | ||||
| CVE-2026-27942 | 1 Naturalintelligence | 1 Fast-xml-parser | 2026-03-02 | 7.5 High |
| fast-xml-parser allows users to validate XML, parse XML to JS object, or build XML from JS object without C/C++ based libraries and no callback. Prior to version 5.3.8, the application crashes with stack overflow when user use XML builder with `preserveOrder:true`. Version 5.3.8 fixes the issue. As a workaround, use XML builder with `preserveOrder:false` or check the input data before passing to builder. | ||||
| CVE-2026-25128 | 1 Naturalintelligence | 1 Fast-xml-parser | 2026-02-27 | 7.5 High |
| fast-xml-parser allows users to validate XML, parse XML to JS object, or build XML from JS object without C/C++ based libraries and no callback. In versions 5.0.9 through 5.3.3, a RangeError vulnerability exists in the numeric entity processing of fast-xml-parser when parsing XML with out-of-range entity code points (e.g., `�` or `�`). This causes the parser to throw an uncaught exception, crashing any application that processes untrusted XML input. Version 5.3.4 fixes the issue. | ||||
| CVE-2023-26920 | 1 Naturalintelligence | 1 Fast Xml Parser | 2024-11-21 | 6.5 Medium |
| fast-xml-parser before 4.1.2 allows __proto__ for Prototype Pollution. | ||||
