CWE-611: XML External Entity (XXE) vulnerabilities

ColdFusion versions 2025.4, 2023.16, 2021.22 and earlier are affected by an Improper Restriction of XML External Entity Reference ('XXE') vulnerability that could lead to arbitrary file system read. A high privileged attacker could exploit this vulnerability to access sensitive files and data on the server. Exploitation of this issue requires user interaction and scope is changed.

Critical XXE in Apache Tika tika-core (1.13-3.2.1), tika-pdf-module (2.0.0-3.2.1) and tika-parsers (1.13-1.28.5) modules on all platforms allows an attacker to carry out XML External Entity injection via a crafted XFA file inside of a PDF. This CVE covers the same vulnerability as in CVE-2025-54988. However, this CVE expands the scope of affected packages in two ways. First, while the entrypoint for the vulnerability was the tika-parser-pdf-module as reported in CVE-2025-54988, the vulnerability and its fix were in tika-core. Users who upgraded the tika-parser-pdf-module but did not upgrade tika-core to >= 3.2.2 would still be vulnerable. Second, the original report failed to mention that in the 1.x Tika releases, the PDFParser was in the "org.apache.tika:tika-parsers" module.

Mustang before 2.16.3 allows exfiltrating files via XXE attacks.

Peppol-py before 1.1.1 allows XXE attacks because of the Saxon configuration. When validating XML-based invoices, the XML parser could read files from the filesystem and expose their content to a remote host.

N-central versions < 2025.4 are vulnerable to multiple XML External Entities injection leading to information disclosure

The CycloneDX core module provides a model representation of the SBOM along with utilities to assist in creating, validating, and parsing SBOMs. Starting in version 2.1.0 and prior to version 11.0.1, the XML `Validator` used by cyclonedx-core-java was not configured securely, making the library vulnerable to XML External Entity (XXE) injection. The fix for GHSA-683x-4444-jxh8 / CVE-2024-38374 was incomplete in that it only fixed parsing of XML BOMs, but not validation. The vulnerability has been fixed in cyclonedx-core-java version 11.0.1. As a workaround, applications can reject XML documents before handing them to cyclonedx-core-java for validation. This may be an option if incoming CycloneDX BOMs are known to be in JSON format.

An XML External Entity (XXE) vulnerability exists in multiple WSO2 products due to improper configuration of the XML parser. The application parses user-supplied XML without applying sufficient restrictions, allowing resolution of external entities. A successful attack could enable a remote, unauthenticated attacker to read sensitive files from the server's filesystem or perform denial-of-service (DoS) attacks that render affected services unavailable.

IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 is vulnerable to an XML external entity injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.

Dell Storage Center - Dell Storage Manager, version(s) 20.1.20, contain(s) an Improper Restriction of XML External Entity Reference vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.

The HTMLSectionSplitter class in langchain-text-splitters version 0.3.8 is vulnerable to XML External Entity (XXE) attacks due to unsafe XSLT parsing. This vulnerability arises because the class allows the use of arbitrary XSLT stylesheets, which are parsed using lxml.etree.parse() and lxml.etree.XSLT() without any hardening measures. In lxml versions up to 4.9.x, external entities are resolved by default, allowing attackers to read arbitrary local files or perform outbound HTTP(S) fetches. In lxml versions 5.0 and above, while entity expansion is disabled, the XSLT document() function can still read any URI unless XSLTAccessControl is applied. This vulnerability allows remote attackers to gain read-only access to any file the LangChain process can reach, including sensitive files such as SSH keys, environment files, source code, or cloud metadata. No authentication, special privileges, or user interaction are required, and the issue is exploitable in default deployments that enable custom XSLT.

A blind XML External Entity (XXE) injection in the OpenMessaging webservice in TecCom TecConnect 4.1 allows an unauthenticated attacker to exfiltrate arbitrary files to an attacker-controlled server. TecConnect 4.1 is considered end-of-life as of December 2023. Users are advised to upgrade to TecCom Connect 5.

Delta Electronics EIP Builder version 1.11 is vulnerable to a File Parsing XML External Entity Processing Information Disclosure Vulnerability.

CVE-2025-54988 is a high-severity XML External Entity (XXE) vulnerability in the Apache Tika PDF parser module affecting versions 1.13 through 3.2.1. It allows attackers to inject malicious XML entities via crafted XFA files inside PDFs, potentially enabling unauthorized reading of sensitive data or triggering malicious requests to internal or external resources. The vulnerability impacts multiple Tika packages that depend on the vulnerable PDF parser module. Users are advised to upgrade to Apache Tika version 3.2.2, which addresses this issue.

Improper Restriction of XML External Entity Reference in various Lexmark printer drivers for Windows allows attacker to disclose sensitive information to an arbitrary URL.

Dell CloudLink, versions 8.0 through 8.1.1, contains an Improper Restriction of XML External Entity Reference vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Denial of service.

A vulnerability has been identified in SIMOTION SCOUT TIA V5.4 (All versions), SIMOTION SCOUT TIA V5.5 (All versions), SIMOTION SCOUT TIA V5.6 (All versions < V5.6 SP1 HF7), SIMOTION SCOUT TIA V5.7 (All versions < V5.7 SP1 HF1), SIMOTION SCOUT V5.4 (All versions), SIMOTION SCOUT V5.5 (All versions), SIMOTION SCOUT V5.6 (All versions < V5.6 SP1 HF7), SIMOTION SCOUT V5.7 (All versions < V5.7 SP1 HF1), SINAMICS STARTER V5.5 (All versions), SINAMICS STARTER V5.6 (All versions), SINAMICS STARTER V5.7 (All versions < V5.7 HF2). The affected application contains a XML External Entity Injection (XXE) vulnerability while parsing specially crafted XML files. This could allow an attacker to read arbitrary files in the system.

OpenKilda is an open-source OpenFlow controller. Prior to version 1.164.0, an XML external entity (XXE) injection vulnerability was found in OpenKilda which in combination with GHSL-2025-024 allows unauthenticated attackers to exfiltrate information from the instance where the OpenKilda UI is running. This issue may lead to Information disclosure. This issue has been patched in version 1.164.0.

In Xerox FreeFlow Core version 8.0.4, improper handling of XML input allows injection of external entities. An attacker can craft malicious XML containing references to internal URLs, this results in a Server-Side Request Forgery (SSRF).

Adobe Experience Manager versions 6.5.23 and earlier are affected by an Improper Restriction of XML External Entity Reference ('XXE') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files on the local file system, scope is changed. Exploitation of this issue does not require user interaction.

Dell SmartFabric OS10 Software, versions prior to 10.6.0.5, contains an Improper Restriction of XML External Entity Reference vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.
