CVE-2026-33737 MEDIUM This Month

Chamilo LMS versions prior to 1.11.38 and 2.0.0-RC.3 allow authenticated attackers to read arbitrary server files through XML External Entity (XXE) injection via improper use of simplexml_load_string() with the LIBXML_NOENT flag enabled across multiple application files. The vulnerability requires low-privilege authentication and medium attack complexity but grants high confidentiality impact with no integrity or availability impact; no public exploit code or active exploitation has been identified at the time of analysis.

CVE-2026-4374 HIGH This Week

RTI Connext Professional (versions unspecified) contains an improper restriction of XML external entity (XXE) reference vulnerability affecting Routing Service, Observability Collector, Recording Service, Queueing Service, and Cloud Discovery Service. Remote attackers can exploit this to achieve serialized data external linking and data serialization bypass, potentially leading to information disclosure or denial of service. CVSS vector and score are not available; exploitation status and POC availability cannot be confirmed from provided data.

CVE-2026-34401 MEDIUM This Month

XML Notepad versions prior to 2.9.0.21 allow remote attackers to leak local file contents or capture NTLM credentials via crafted XML files with malicious DTDs, exploiting disabled-by-default DTD processing that automatically resolves external entities. The vulnerability requires user interaction (opening a malicious XML file) but poses significant confidentiality risk on Windows systems where NTLM credential interception is feasible. Microsoft released patched version 2.9.0.21 to address this XXE (XML External Entity) issue.

Inkscape 1.1 before 1.3 contains a local file disclosure vulnerability in XInclude processing that allows unauthenticated remote attackers to read arbitrary files from an affected system by crafting malicious SVG files with xi:include tags. The vulnerability has a moderate CVSS score of 6.3 but carries high confidentiality impact; no public exploit code or active exploitation has been confirmed at the time of analysis. Upstream fixes are available via GitLab merge requests, and users should upgrade to version 1.3 or later.

OpenEMR versions prior to 8.0.0.3 contain an XML External Entity (XXE) injection vulnerability in the Carecoordination module that allows authenticated users to read arbitrary files from the server. Attackers can exploit this by uploading a maliciously crafted CCDA document containing XXE payloads to access sensitive server files such as /etc/passwd. A patch is available in version 8.0.0.3, and this vulnerability has a CVSS score of 7.7 with high confidentiality impact.

An XML External Entity (XXE) vulnerability exists in Zimbra Collaboration Server (ZCS) versions 10.0 and 10.1 within the Exchange Web Services (EWS) SOAP interface due to improper XML input handling. An authenticated attacker can submit crafted XML payloads to an XML parser with external entity resolution enabled, potentially disclosing sensitive local files from the server. No CVSS score, EPSS data, or known exploitation-in-the-wild status is currently available, though the vulnerability has been documented in Zimbra's security advisory system.

An XML External Entity (XXE) vulnerability in the XMLUtils.java component of Slovensko.Digital Autogram allows remote unauthenticated attackers to conduct Server-Side Request Forgery (SSRF) attacks and read local files from the filesystem. The vulnerability affects Autogram software and can be exploited when a victim visits a specially crafted website that sends malicious XML to the application's local HTTP server /sign endpoint. A blog post detailing exploitation research is publicly available, increasing the likelihood of exploitation attempts.
