CVE-2025-5466 2025-08-12 N/A N/A
XEE in Ivanti Connect Secure before 22.7R2.8 or 22.8R2, Ivanti Policy Secure before 22.7R1.5, Ivanti ZTA Gateway before 22.8R2.3-723 and Ivanti Neurons for Secure Access before 22.8R1.4 (Fix deployed on 02-Aug-2025) allows a remote authenticated attacker with admin privileges to trigger a denial of service
CVE-2025-3225 1 Llamaindex 1 Llamaindex 2025-07-30 N/A N/A
An XML Entity Expansion vulnerability, also known as a 'billion laughs' attack, exists in the sitemap parser of the run-llama/llama_index repository, specifically affecting version v0.12.21. This vulnerability allows an attacker to supply a malicious Sitemap XML, leading to a Denial of Service (DoS) by exhausting system memory and potentially causing a system crash. The issue is resolved in version v0.12.29.
CVE-2023-52426 1 Libexpat Project 1 Libexpat 2025-06-17 N/A 5.5 MEDIUM
libexpat through 2.5.0 allows recursive XML Entity Expansion if XML_DTD is undefined at compile time.
CVE-2019-15903 2 Libexpat Project, Python 2 Libexpat, Python 2025-05-30 5.0 MEDIUM 7.5 HIGH
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
CVE-2022-44641 2 Debian, Linaro 2 Debian Linux, Lava 2025-04-29 N/A 6.5 MEDIUM
In Linaro Automated Validation Architecture (LAVA) before 2022.11, users with valid credentials can submit crafted XMLRPC requests that cause a recursive XML entity expansion, leading to excessive use of memory on the server and a Denial of Service.
CVE-2024-28757 3 Fedoraproject, Libexpat Project, Netapp 21 Fedora, Libexpat, Active Iq Unified Manager and 18 more 2025-03-28 N/A 7.5 HIGH
libexpat through 2.6.1 allows an XML Entity Expansion attack when there is isolated use of external parsers (created via XML_ExternalEntityParserCreate).
CVE-2022-28652 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2025-03-13 N/A 5.5 MEDIUM
~/.config/apport/settings parsing is vulnerable to "billion laughs" attack
CVE-2025-0617 2025-01-29 N/A N/A
An attacker with access to an HX 10.0.0 and previous versions, may send specially-crafted data to the HX console. The malicious detection would then trigger file parsing containing exponential entity expansions in the consumer process thus causing a Denial of Service.
CVE-2021-1267 1 Cisco 1 Secure Firewall Management Center 2024-11-26 4.0 MEDIUM 4.3 MEDIUM
A vulnerability in the dashboard widget of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper restrictions on XML entities. An attacker could exploit this vulnerability by crafting an XML-based widget on an affected server. A successful exploit could cause increased memory and CPU utilization, which could result in a DoS condition.
CVE-2024-28982 1 Hitachi 1 Pentaho Business Analytics Server 2024-09-18 N/A 8.2 HIGH
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-2022-25857 2 Debian, Snakeyaml Project 2 Debian Linux, Snakeyaml 2024-03-15 N/A 7.5 HIGH
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-2011-3288 1 Cisco 1 Unified Presence 2024-02-15 7.8 HIGH 7.5 HIGH
Cisco Unified Presence before 8.5(4) does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption, and process crash) via a crafted XML document containing a large number of nested entity references, aka Bug IDs CSCtq89842 and CSCtq88547, a similar issue to CVE-2003-1564.
CVE-2008-3281 7 Apple, Canonical, Debian and 4 more 11 Iphone Os, Safari, Ubuntu Linux and 8 more 2024-02-02 4.3 MEDIUM 6.5 MEDIUM
libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.
CVE-2011-1755 3 Apple, Fedoraproject, Jabberd2 4 Mac Os X, Mac Os X Server, Fedora and 1 more 2024-02-02 5.0 MEDIUM 7.5 HIGH
jabberd2 before 2.2.14 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.
CVE-2009-1955 7 Apache, Apple, Canonical and 4 more 8 Apr-util, Http Server, Mac Os X and 5 more 2024-02-02 5.0 MEDIUM 7.5 HIGH
The expat XML parser in the apr_xml_* interface in xml/apr_xml.c in Apache APR-util before 1.3.7, as used in the mod_dav and mod_dav_svn modules in the Apache HTTP Server, allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, as demonstrated by a PROPFIND request, a similar issue to CVE-2003-1564.
CVE-2003-1564 1 Xmlsoft 1 Libxml2 2024-02-02 9.3 HIGH 6.5 MEDIUM
libxml2, possibly before 2.5.0, does not properly detect recursion during entity expansion, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, aka the "billion laughs attack."
CVE-2023-20052 3 Cisco, Clamav, Stormshield 4 Secure Endpoint, Secure Endpoint Private Cloud, Clamav and 1 more 2024-01-25 N/A 5.3 MEDIUM
On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the DMG file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to access sensitive information on an affected device. This vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.
CVE-2023-49967 1 Typecho 1 Typecho 2023-12-09 N/A 7.5 HIGH
Typecho v1.2.1 was discovered to be vulnerable to an XML Quadratic Blowup attack via the component /index.php/action/xmlrpc.
CVE-2022-0217 1 Prosody 1 Prosody 2023-11-07 N/A 7.5 HIGH
It was discovered that an internal Prosody library to load XML based on libexpat does not properly restrict the XML features allowed in parsed XML data. Given suitable attacker input, this results in expansion of recursive entity references from DTDs (CWE-776). In addition, depending on the libexpat version used, it may also allow injections using XML External Entity References (CWE-611).
CVE-2021-23926 4 Apache, Debian, Netapp and 1 more 7 Xmlbeans, Debian Linux, Oncommand Unified Manager Core Package and 4 more 2023-11-07 6.4 MEDIUM 9.1 CRITICAL
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.
