CVE Severity Published▾ Status Exploitation Description
CVE-2026-2736 Medium 2026-02-19 Not applicable No public exploit Reflected Cross-site Scripting (XSS) in Alkacon's OpenCms v18.0, which allows an attacker to execute JavaScript code in the victim's browser by sending the victim a malicious URL containing the ‘q’ parameter in ‘/search/index.html’. This vulnerability can be exploited to steal sensitive user information such as session cookies, or to perform actions while impersonating the user.
CVE-2026-2735 Medium 2026-02-19 Not applicable No public exploit Stored Cross-Site Scripting (XSS) in Alkacon's OpenCms v18.0, which occurs when user input is not properly validated when sending a POST request to ‘/blog/new-article/org.opencms.ugc.CmsUgcEditService.gwt’ using the ‘text’ parameter.
CVE-2024-5521 Medium 2024-05-30 Not applicable No public exploit Two Cross-Site Scripting vulnerabilities have been discovered in Alkacon's OpenCMS affecting version 16, which could allow a user having the roles of gallery editor or VFS resource manager will have the permission to upload images in the .svg format containing JavaScript code. The code will be executed the moment another user accesses the image.
CVE-2023-6380 Medium 2023-12-13 Not applicable Working exploit published Open redirect vulnerability has been found in the Open CMS product affecting versions 14 and 15 of the 'Mercury' template. An attacker could create a specially crafted URL and send it to a specific user to redirect them to a malicious site and compromise them. Exploitation of this vulnerability is possible due to the fact that there is no proper sanitization of the 'URI' parameter.
CVE-2021-25968 Medium 2021-10-19 Not applicable Proof of concept only In “OpenCMS”, versions 10.5.0 to 11.0.2 are affected by a stored XSS vulnerability that allows low privileged application users to store malicious scripts in the Sitemap functionality. These scripts are executed in a victim’s browser when they open the page containing the vulnerable field.
CVE-2018-8815 Medium 2018-03-20 Not applicable Working exploit published Cross-site scripting (XSS) vulnerability in the gallery function in Alkacon OpenCMS 10.5.3 allows remote attackers to inject arbitrary web script or HTML via a malicious SVG image.
CVE-2018-8811 High 2018-03-20 Not applicable Working exploit published Cross-site request forgery (CSRF) vulnerability in system/workplace/admin/accounts/user_role.jsp in OpenCMS 10.5.3 allows remote attackers to hijack the authentication of administrative users for requests that perform privilege escalation. Note: It is argued that OpenCMS allows only registered users to upload different kind of content artifacts (SVG, .doc, .docx). The uploaded content is stored in the CMS content repository "as is". In case of scripts inside an SVG, this may or may not be "malicious", there is no way of knowing if the uploaded SVG contains the script for a reason. To exploit the "issue", a user must have an account in the CMS as a content manager
CVE-2009-4505 Medium 2010-03-26 Not applicable No public exploit Multiple cross-site scripting (XSS) vulnerabilities in OpenCMS OAMP Comments Module 1.0.1 allow remote attackers to inject arbitrary web script or HTML via the name field in a comment, and other unspecified vectors.
CVE-2005-4475 Medium 2005-12-22 Not applicable No public exploit Cross-site scripting (XSS) vulnerability in OpenCms 6.0.3 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified search parameters.
