CVE-2026-119724 High 2026-11-03 Protected by Waratek No public exploit ** UNSUPPORTED WHEN ASSIGNED ** Improper restriction of recursive entity references in DTDs ('XML entity expansion') vulnerability in Apache JClouds. This issue affects Apache JClouds: all versions. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2026-111252 Medium 2026-10-15 Protected by Waratek No public exploit A denial of service vulnerability exists in the XML parsing of multiple versions of OpenNMS Meridian and Horizon. OpenNMS parsed XML without an effective limit on entity expansion. A document with a DOCTYPE that declares internal entities can expand to a very large value and exhaust the server memory. An authenticated user with provisioning access can supply such a document through a requisition or foreign-source import, which includes a remote requisition URL that the server fetches and parses. Both deeply nested entities and a single large entity referenced many times cause the memory exhaustion. The fix caps the number of entity expansions for all XML parsing and rejects any DOCTYPE in requisition and foreign-source XML. The solution is to upgrade to Meridian 2024.3.14, 2025.0.11, 2026.0.1 and Horizon 36.0.5 or newer. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet.
CVE-2026-108039 High 2026-10-09 No exploit published No public exploit By default, StaxUtils placed no limit on the total number of elements or the total number of characters in an XML document. A very large request could therefore use a lot of memory and CPU during parsing, especially where CXF builds a DOM from the input (for example SAAJ or WS-Security), and could cause a denial of service when no request size limit was configured. Both limits now have defaults: the maximum element count is 100 × maxChildElements (5,000,000 by default), and the maximum document size is 256M characters. Applications that process larger documents can raise the limits with the org.apache.cxf.stax.maxElementCount and org.apache.cxf.stax.maxXMLCharacters properties. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
CVE-2026-54077 High 2026-09-15 Protected by Waratek No public exploit ArcadeDB is a Multi-Model DBMS. Prior to 26.6.1, the IMPORT DATABASE statement in engine/src/main/java/com/arcadedb/query/sql/parser/ImportDatabaseStatement.java did not require administrative privileges and passed its source to integration/src/main/java/com/arcadedb/integration/importer/SourceDiscovery.java without validation. An authenticated user with SQL command access through /api/v1/command or /api/v1/query can supply HTTP or HTTPS destinations to make server-side requests to internal services, or file:// paths to read files accessible to the server process and ingest the results as queryable records. The XML importer also permits DTD processing and external entities, enabling entity expansion. The root-only /api/v1/server administration endpoint is not affected. The fix requires updateSecurity permission, blocks local-network import destinations by default through arcadedb.server.security.importBlockLocalNetworks, supports the arcadedb.server.security.importAllowedLocalPaths file allow-list, and disables XML DTD processing and external entities. This issue is fixed in version 26.6.1.
CVE-2026-3415 High 2026-08-06 Protected by Waratek No public exploit The XML and schema validation functionalities within the SchemaValidator Mediator process XML input as part of validation flows. Under certain conditions, the XML parser allows the resolution of external entities when handling user-supplied XML content during validation operations. This behavior can occur when an attacker supplies crafted XML payloads to the relevant mediator flows with sufficient privileges. Successful exploitation may allow a highly privileged actor to read files accessible within the server hosting the affected product. Additionally, it may be possible to trigger outbound requests to unintended internal or external locations, depending on the server environment and network configuration. Specially crafted XML payloads can also lead to excessive resource consumption during parsing, impacting the availability of the product.
CVE-2026-12993 Medium 2026-06-26 Protected by Waratek No public exploit A flaw was found in Apicurio Registry. The DocumentBuilderAccessor correctly blocks external DTD and schema access but does not disable DOCTYPE declarations or enable FEATURE_SECURE_PROCESSING. An attacker with artifact-write permission can upload XML documents with internal entity-expansion payloads (billion-laughs variant) that cause CPU and heap exhaustion, partially mitigated by the JAXP default 64,000 entity-expansion limit.
CVE-2024-28982 High 2024-06-26 Protected by Waratek No public exploit Hitachi Vantara Pentaho Business Analytics Server versions before 10.1.0.0 and 9.3.0.7, including 8.3.x do not correctly protect the ACL service endpoint of the Pentaho User Console against XML External Entity Reference.
CVE-2023-49735 High 2023-11-30 Protected by Waratek No public exploit ** UNSUPPORTED WHEN ASSIGNED ** The value set as the DefaultLocaleResolver.LOCALE_KEY attribute on the session was not validated while resolving XML definition files, leading to possible path traversal and eventually SSRF/XXE when passing user-controlled data to this key. Passing user-controlled data to this key may be relatively common, as it was also used like that to set the language in the 'tiles-test' application shipped with Tiles. This issue affects Apache Tiles from version 2 onwards. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2023-28118 High 2023-03-20 Protected by Waratek No public exploit kaml provides YAML support for kotlinx.serialization. Prior to version 0.53.0, applications that use kaml to parse untrusted input containing anchors and aliases may consume excessive memory and crash. Version 0.53.0 and later default to refusing to parse YAML documents containing anchors and aliases. There are no known workarounds.
CVE-2023-24443 Critical 2023-01-26 Protected by Waratek No public exploit Jenkins TestComplete support Plugin 2.8.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
CVE-2023-24441 Critical 2023-01-26 Protected by Waratek No public exploit Jenkins MSTest Plugin 1.0.0 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
CVE-2022-25857 High 2022-08-30 Protected by Waratek No public exploit The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due missing to nested depth limitation for collections.
CVE-2022-23640 Critical 2022-03-02 Protected by Waratek No public exploit Excel-Streaming-Reader is an easy-to-use implementation of a streaming Excel reader using Apache POI. Prior to xlsx-streamer 2.1.0, the XML parser that was used did apply all the necessary settings to prevent XML Entity Expansion issues. Upgrade to version 2.1.0 to receive a patch. There is no known workaround.
CVE-2021-32623 High 2021-06-16 Protected by Waratek No public exploit Opencast is a free and open source solution for automated video capture and distribution. Versions of Opencast prior to 9.6 are vulnerable to the billion laughs attack, which allows an attacker to easily execute a (seemingly permanent) denial of service attack, essentially taking down Opencast using a single HTTP request. To exploit this, users need to have ingest privileges, limiting the group of potential attackers The problem has been fixed in Opencast 9.6. There is no known workaround for this issue.
CVE-2021-23926 Critical 2021-01-14 Protected by Waratek No public exploit The XML parsers used by XMLBeans up to version 2.6.0 did not set the properties needed to protect the user from malicious XML input. Vulnerabilities include possibilities for XML Entity Expansion attacks. Affects XMLBeans up to and including v2.6.0.
CVE-2020-2172 Medium 2020-04-07 Protected by Waratek No public exploit Jenkins Code Coverage API Plugin 1.1.4 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
CVE-2017-18640 High 2019-12-12 Protected by Waratek No public exploit The Alias feature in SnakeYAML before 1.26 allows entity expansion during a load operation, a related issue to CVE-2003-1564.
CVE-2019-12401 High 2019-09-10 Protected by Waratek No public exploit Solr versions 1.3.0 to 1.4.1, 3.1.0 to 3.6.2 and 4.0.0 to 4.10.4 are vulnerable to an XML resource consumption attack (a.k.a. Lol Bomb) via it’s update handler.?By leveraging XML DOCTYPE and ENTITY type elements, the attacker can create a pattern that will expand when the server parses the XML causing OOMs.
CVE-2019-5442 High 2019-06-12 Protected by Waratek No public exploit XML Entity Expansion (Billion Laughs Attack) on Pippo 1.12.0 results in Denial of Service.Entities are created recursively and large amounts of heap memory is taken. Eventually, the JVM process will run out of memory. Otherwise, if the OS does not bound the memory on that process, memory will continue to be exhausted and will affect other processes on the system.
CVE-2019-5427 High 2019-04-22 Protected by Waratek No public exploit c3p0 version < 0.9.5.4 may be exploited by a billion laughs attack when loading XML configuration due to missing protections against recursive entity expansion when loading configuration.
CVE-2017-5644 Medium 2017-03-24 Protected by Waratek No public exploit Apache POI in versions prior to release 3.15 allows remote attackers to cause a denial of service (CPU consumption) via a specially crafted OOXML file, aka an XML Entity Expansion (XEE) attack.
CVE-2014-1868 Medium 2014-10-06 Protected by Waratek No public exploit Restlet Framework 2.1.x before 2.1.7 and 2.x.x before 2.2 RC1, when using XMLRepresentation or XML serializers, allows attackers to cause a denial of service via an XML Entity Expansion (XEE) attack.
