CWE-91
XML Injection (aka Blind XPath Injection)
BaseDraft
Description
The product does not properly neutralize special elements that are used in XML, allowing attackers to modify the syntax, content, or commands of the XML before it is processed by an end system.
Within XML, special elements could include reserved words or characters such as "<", ">", """, and "&", which could then be used to add new data or modify XML syntax.

|---|---|---|---|---|---|---|---|
| CVE-2022-50902 | Hig | 0.55 | 8.4 | 0.00 | Jan 13, 2026 | Wondershare FamiSafe 1.0 contains an unquoted service path vulnerability in the FSService that allows local users to potentially execute code with elevated privileges. Attackers can exploit the unquoted path in C:\Program Files (x86)\Wondershare\FamiSafe\ to inject malicious code that would run with LocalSystem permissions during service startup. | |
| CVE-2025-25589 | Hig | 0.53 | 8.1 | 0.00 | Mar 18, 2025 | An XML external entity (XXE) injection vulnerability in the component /weixin/aes/XMLParse.java of yimioa before v2024.07.04 allows attackers to execute arbitrary code via supplying a crafted XML file. | |
| CVE-2026-32870 | Hig | 0.49 | 7.5 | 0.00 | Apr 24, 2026 | Kirby is an open-source content management system. Kirby's `Xml::value()` method has special handling for `<![CDATA[ ]]>` blocks. If the input value is already valid `CDATA`, it is not escaped a second time but allowed to pass through. However, prior to versions 4.9.0 and 5.4.0, it was possible to trick this check into allowing values that only contained a valid `CDATA` block but also contained other structured data outside of the `CDATA` block. This structured data would then also be allowed to pass through, circumventing the value protection. The `Xml::value()` method is used in `Xml::tag()`, `Xml::create()` and in the `Xml` data handler (e.g. `Data::encode($string, 'xml')`). Both the vulnerable methods and the data handler are not used in the Kirby core. However they may be used in site or plugin code, e.g. to create XML strings from input data. If those generated files are passed to another implementation that assigns specific meaning to the XML schema, manipulation of this system's behavior is possible. Kirby sites that don't use XML generation in site or plugin code are not affected. The problem has been patched in Kirby 4.9.0 and Kirby 5.4.0. In all of the mentioned releases, Kirby has added additional checks that only allow unchanged `CDATA` passthrough if the entire string is made up of valid `CDATA` blocks and no structured data. This protects all uses of the method against the described vulnerability. | |
| CVE-2024-28109 | Hig | 0.46 | 8.1 | 0.01 | Mar 28, 2024 | veraPDF-library is a PDF/A validation library. Executing policy checks using custom schematron files invokes an XSL transformation that could lead to a remote code execution (RCE) vulnerability. This vulnerability is fixed in 1.24.2. | |
| CVE-2025-9375 | Med | 0.45 | — | 0.00 | Sep 1, 2025 | XML Injection vulnerability in xmltodict allows Input Data Manipulation. This issue affects xmltodict: from 0.14.2 before 0.15.1. NOTE: the scope of this CVE is disputed by the vendor on the grounds that xmltodict.unparse() delegates element-name handling to Python's xml.sax.saxutils.XMLGenerator, and that XMLGenerator should be the component performing validation. | |
| CVE-2026-34601 | Hig | 0.42 | 7.5 | 0.00 | Apr 2, 2026 | xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module. In xmldom versions 0.6.0 and prior and @xmldom/xmldom prior to versions 0.8.12 and 0.9.9, xmldom/xmldom allows attacker-controlled strings containing the CDATA terminator ]]> to be inserted into a CDATASection node. During serialization, XMLSerializer emitted the CDATA content verbatim without rejecting or safely splitting the terminator. As a result, data intended to remain text-only became active XML markup in the serialized output, enabling XML structure injection and downstream business-logic manipulation. This issue has been patched in xmldom version 0.6.0 and @xmldom/xmldom versions 0.8.12 and 0.9.9. | |
| CVE-2024-13190 | Med | 0.41 | 6.3 | 0.00 | Jan 8, 2025 | A vulnerability classified as critical was found in ZeroWdd myblog 1.0. This vulnerability affects unknown code of the file src/main/resources/mapper/BlogMapper.xml. The manipulation of the argument findBlogList/getTotalBlogs leads to xml injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. | |
| CVE-2026-27693 | Med | 0.35 | 5.4 | 0.00 | May 5, 2026 | Traccar is an open source GPS tracking system. In org.traccar:traccar versions starting at 6.11.1 before 6.13.0, the KML and GPX export functionality writes device names to XML output without proper escaping. An attacker with low privileges can create a device with a crafted name that injects XML content into exported files. If another user exports and opens the affected KML or GPX file, this can corrupt the file structure and spoof exported location data. This issue is fixed in version 6.13.0. | |
| CVE-2025-47184 | Med | 0.34 | 5.3 | 0.00 | Aug 21, 2025 | An XML external entities (XXE) injection vulnerability in the /init API endpoint in Exagid EX10 before 6.4.0 P20, 7.0.1 P12, and 7.2.0 P08 allows an authenticated, unprivileged attacker to achieve information disclosure and privilege escalation via a crafted ISys XML message. | |
| CVE-2025-12921 | Med | 0.28 | 4.3 | 0.00 | Nov 10, 2025 | A vulnerability has been found in OpenClinica Community Edition up to 3.12.2/3.13. Affected by this issue is some unknown functionality of the file /ImportCRFData?action=confirm of the component CRF Data Import. Such manipulation of the argument xml_file leads to xml injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | |
| CVE-2008-5024 | 0.01 | — | 0.07 | Nov 13, 2008 | Mozilla Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 do not properly escape quote characters used for XML processing, which allows remote attackers to conduct XML injection attacks via the default namespace in an E4X document. | ||
