CVE-2021-41831 1 Apache 1 Openoffice 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
It is possible for an attacker to manipulate the timestamp of signed documents. All versions of Apache OpenOffice up to 4.1.10 are affected. Users are advised to update to version 4.1.11. See CVE-2021-25634 for the LibreOffice advisory.
CVE-2021-41830 1 Apache 1 Openoffice 2026-06-17 5.0 MEDIUM 7.5 HIGH
It is possible for an attacker to manipulate signed documents and macros to appear to come from a trusted source. All versions of Apache OpenOffice up to 4.1.10 are affected. Users are advised to update to version 4.1.11. See CVE-2021-25633 for the LibreOffice advisory.
CVE-2021-41773 4 Apache, Fedoraproject, Netapp and 1 more 4 Http Server, Fedora, Cloud Backup and 1 more 2026-06-17 4.3 MEDIUM 9.8 CRITICAL
A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013.
CVE-2021-41767 1 Apache 1 Guacamole 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
Apache Guacamole 1.3.0 and older may incorrectly include a private tunnel identifier in the non-private details of some REST responses. This may allow an authenticated user who already has permission to access a particular connection to read from or interact with another user's active use of that same connection.
CVE-2021-41766 1 Apache 1 Karaf 2026-06-17 6.8 MEDIUM 8.1 HIGH
Apache Karaf allows monitoring of applications and the Java runtime by using the Java Management Extensions (JMX). JMX is a Java RMI based technology that relies on Java serialized objects for client server communication. Whereas the default JMX implementation is hardened against unauthenticated deserialization attacks, the implementation used by Apache Karaf is not protected against this kind of attack. The impact of Java deserialization vulnerabilities strongly depends on the classes that are available within the targets class path. Generally speaking, deserialization of untrusted data does always represent a high security risk and should be prevented. The risk is low as, by default, Karaf uses a limited set of classes in the JMX server class path. It depends of system scoped classes (e.g. jar in the lib folder).
CVE-2021-41616 1 Apache 1 Ddlutils 2026-06-17 7.5 HIGH 9.8 CRITICAL
Apache DB DdlUtils 1.0 included a BinaryObjectsHelper that was intended for use when migrating database data with a SQL data type of BINARY, VARBINARY, LONGVARBINARY, or BLOB between databases using the ddlutils features. The BinaryObjectsHelper class was insecure and used ObjectInputStream.readObject without validating that the input data was safe to deserialize. Please note that DdlUtils is no longer being actively developed. To address the insecurity of the BinaryObjectHelper class, the following changes to DdlUtils have been made: (1) BinaryObjectsHelper.java has been deleted from the DdlUtils source repository and the DdlUtils feature of propagating data of SQL binary types is therefore no longer present in DdlUtils; (2) The ddlutils-1.0 release has been removed from the Apache Release Distribution Infrastructure; (3) The DdlUtils web site has been updated to indicate that DdlUtils is now available only as source code, not as a packaged release.
CVE-2021-41585 1 Apache 1 Traffic Server 2026-06-17 5.0 MEDIUM 7.5 HIGH
Improper Input Validation vulnerability in accepting socket connections in Apache Traffic Server allows an attacker to make the server stop accepting new connections. This issue affects Apache Traffic Server 5.0.0 to 9.1.0.
CVE-2021-41571 1 Apache 1 Pulsar 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
In Apache Pulsar it is possible to access data from BookKeeper that does not belong to the topics accessible by the authenticated user. The Admin API get-message-by-id requires the user to input a topic and a ledger id. The ledger id is a pointer to the data, and it is supposed to be a valid it for the topic. Authorisation controls are performed against the topic name and there is not proper validation the that ledger id is valid in the context of such ledger. So it may happen that the user is able to read from a ledger that contains data owned by another tenant. This issue affects Apache Pulsar Apache Pulsar version 2.8.0 and prior versions; Apache Pulsar version 2.7.3 and prior versions; Apache Pulsar version 2.6.4 and prior versions.
CVE-2021-41561 1 Apache 1 Parquet Java 2026-06-17 5.0 MEDIUM 7.5 HIGH
Improper Input Validation vulnerability in Parquet-MR of Apache Parquet allows an attacker to DoS by malicious Parquet files. This issue affects Apache Parquet-MR version 1.9.0 and later versions.
CVE-2021-41532 1 Apache 1 Ozone 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
In Apache Ozone before 1.2.0, Recon HTTP endpoints provide access to OM, SCM and Datanode metadata. Due to a bug, any unauthenticated user can access the data from these endpoints.
CVE-2021-41524 4 Apache, Fedoraproject, Netapp and 1 more 4 Http Server, Fedora, Cloud Backup and 1 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project.
CVE-2021-41303 2 Apache, Oracle 2 Shiro, Financial Services Crime And Compliance Management Studio 2026-06-17 7.5 HIGH 9.8 CRITICAL
Apache Shiro before 1.8.0, when using Apache Shiro with Spring Boot, a specially crafted HTTP request may cause an authentication bypass. Users should update to Apache Shiro 1.8.0.
CVE-2021-41079 3 Apache, Debian, Netapp 3 Tomcat, Debian Linux, Management Services For Element Software And Netapp Hci 2026-06-17 4.3 MEDIUM 7.5 HIGH
Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service.
CVE-2021-40865 1 Apache 1 Storm 2026-06-17 7.5 HIGH 9.8 CRITICAL
An Unsafe Deserialization vulnerability exists in the worker services of the Apache Storm supervisor server allowing pre-auth Remote Code Execution (RCE). Apache Storm 2.2.x users should upgrade to version 2.2.1 or 2.3.0. Apache Storm 2.1.x users should upgrade to version 2.1.1. Apache Storm 1.x users should upgrade to version 1.2.4
CVE-2021-40690 3 Apache, Debian, Oracle 18 Cxf, Santuario Xml Security For Java, Tomee and 15 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
All versions of Apache Santuario - XML Security for Java prior to 2.2.3 and 2.1.7 are vulnerable to an issue where the "secureValidation" property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. This allows an attacker to abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.
CVE-2021-40525 1 Apache 1 James 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
Apache James ManagedSieve implementation alongside with the file storage for sieve scripts is vulnerable to path traversal, allowing reading and writing any file. This vulnerability had been patched in Apache James 3.6.1 and higher. We recommend the upgrade. Distributed and Cassandra based products are also not impacted.
CVE-2021-40439 1 Apache 1 Openoffice 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
Apache OpenOffice has a dependency on expat software. Versions prior to 2.1.0 were subject to CVE-2013-0340 a "Billion Laughs" entity expansion denial of service attack and exploit via crafted XML files. ODF files consist of a set of XML files. All versions of Apache OpenOffice up to 4.1.10 are subject to this issue. expat in version 4.1.11 is patched.
CVE-2021-40438 11 Apache, Broadcom, Debian and 8 more 40 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 37 more 2026-06-17 6.8 MEDIUM 9.0 CRITICAL
