CVE-2025-64407 5.3 MEDIUM EPSS 0.00

Apache OpenOffice documents can contain links. A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. Such links could also be used to transmit system information, such as environment variables or configuration settings. In the affected versions of Apache OpenOffice, documents that used a certain URI scheme linking to external files would load the contents of such files without prompting the user for permission to do so. Such URI scheme allows to include system configuration data, that is not supposed to be transmitted externally. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue. The LibreOffice suite reported this issue as CVE-2024-12426.

CWE-201 Nov 12, 2025

CVE-2025-64406 4.3 MEDIUM EPSS 0.00

An out-of-bounds Write vulnerability in Apache OpenOffice could allow an attacker to craft a document that would crash the program, or otherwise corrupt other memory areas. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue.

CWE-787 Nov 12, 2025

CVE-2025-64405 7.5 HIGH EPSS 0.00

Apache OpenOffice documents can contain links. A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of Apache OpenOffice, Calc spreadsheet containing DDE links to external files would load the contents of those files without prompting the user for permission to do so. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue.

CWE-862 Nov 12, 2025

CVE-2025-64404 7.5 HIGH EPSS 0.00

Apache OpenOffice documents can contain links to other files. A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of Apache OpenOffice, documents that used background fill images, or bullet images, linked to external files would load the contents of those files without prompting the user for permission to do so. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue.

CWE-862 Nov 12, 2025

CVE-2025-64403 8.1 HIGH EPSS 0.00

Apache OpenOffice Calc spreadsheet can contain links to other files, in the form of "external data sources". A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause such links to be loaded without prompt. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue.

CWE-862 Nov 12, 2025

CVE-2025-64401 7.5 HIGH EPSS 0.00

Apache OpenOffice documents can contain links. A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of Apache OpenOffice, documents that used "floating frames" linked to external files would load the contents of those frames without prompting the user for permission to do so. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue. The LibreOffice suite reported this issue as CVE-2023-2255

CWE-862 Nov 12, 2025

CVE-2023-47804 8.8 HIGH EPSS 0.03

Apache OpenOffice documents can contain links that call internal macros with arbitrary arguments. Several URI Schemes are defined for this purpose. Links can be activated by clicks, or by automatic document events. The execution of such links must be subject to user approval. In the affected versions of OpenOffice, approval for certain links is not requested; when activated, such links could therefore result in arbitrary script execution. This is a corner case of CVE-2022-47502.

CWE-88 Mar 24, 2023

CVE-2022-38745 7.8 HIGH EPSS 0.00

Apache OpenOffice versions before 4.1.14 may be configured to add an empty entry to the Java class path. This may lead to run arbitrary Java code from the current directory.

CWE-1188 Mar 24, 2023

CVE-2022-37401 8.8 HIGH EPSS 0.00

Apache OpenOffice supports the storage of passwords for web connections in the user's configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in OpenOffice existed where master key was poorly encoded resulting in weakening its entropy from 128 to 43 bits making the stored passwords vulnerable to a brute force attack if an attacker has access to the users stored config. This issue affects: Apache OpenOffice versions prior to 4.1.13. Reference: CVE-2022-26307 - LibreOffice

CWE-331 Aug 15, 2022

CVE-2022-37400 8.8 HIGH EPSS 0.00

Apache OpenOffice supports the storage of passwords for web connections in the user's configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in OpenOffice existed where the required initialization vector for encryption was always the same which weakens the security of the encryption making them vulnerable if an attacker has access to the user's configuration data. This issue affects: Apache OpenOffice versions prior to 4.1.13. Reference: CVE-2022-26306 - LibreOffice

CWE-330 Aug 15, 2022

CVE-2021-41832 7.5 HIGH EPSS 0.01

It is possible for an attacker to manipulate documents to appear to be signed by 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-2021-25635 for the LibreOffice advisory.

CWE-347 Oct 11, 2021

CVE-2021-41831 5.3 MEDIUM EPSS 0.03

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.

CWE-347 Oct 11, 2021

CVE-2021-41830 7.5 HIGH EPSS 0.01

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.

CWE-347 Oct 11, 2021

CVE-2021-40439 6.5 MEDIUM EPSS 0.00

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.

CWE-611 Oct 07, 2021

CVE-2021-28129 7.8 HIGH EPSS 0.00

While working on Apache OpenOffice 4.1.8 a developer discovered that the DEB package did not install using root, but instead used a userid and groupid of 500. This both caused issues with desktop integration and could allow a crafted attack on files owned by that user or group if they exist. Users who installed the Apache OpenOffice 4.1.8 DEB packaging should upgrade to the latest version of Apache OpenOffice.

CWE-284 Oct 07, 2021

CVE-2021-33035 7.8 HIGH EXPLOITED 1 Writeup EPSS 0.06

Apache OpenOffice opens dBase/DBF documents and shows the contents as spreadsheets. DBF are database files with data organized in fields. When reading DBF data the size of certain fields is not checked: the data is just copied into local variables. A carefully crafted document could overflow the allocated space, leading to the execution of arbitrary code by altering the contents of the program stack. This issue affects Apache OpenOffice up to and including version 4.1.10

CWE-120 Sep 23, 2021

CVE-2021-30245 8.8 HIGH EPSS 0.00

The project received a report that all versions of Apache OpenOffice through 4.1.8 can open non-http(s) hyperlinks. The problem has existed since about 2006 and the issue is also in 4.1.9. If the link is specifically crafted this could lead to untrusted code execution. It is always best practice to be careful opening documents from unknown and unverified sources. The mitigation in Apache OpenOffice 4.1.10 (unreleased) assures that a security warning is displayed giving the user the option of continuing to open the hyperlink.

CWE-610 Apr 15, 2021

CVE-2020-13958 7.8 HIGH 1 PoC Analysis EPSS 0.01

A vulnerability in Apache OpenOffice scripting events allows an attacker to construct documents containing hyperlinks pointing to an executable on the target users file system. These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol may be called from the document event handler and other hyperlinks require a control-click.
