Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.1 and 6.5.4, the HTML sanitizer for ticket articles was missing proper sanitization of data: ... URI schemes, resulting in storing such malicious content in the database of the Zammad instance. The Zammad GUI is rendering this content, due to applied CSP rules no harm was done by e.g., clicking such a link. This vulnerability is fixed in 7.0.1 and 6.5.4.

CVE-2026-489106.5 MED—
———A carefully crafted editing request could trigger an XSS vulnerability
on Apache JSPWiki when parsing errors on the markdown renderer, which
could allow the attacker to execute javascript in the victim's browser
and get some sensitive information about the victim.
This issue affects Apache JSPWiki: through 2.12.3.
Users are recommended to upgrade to version 2.12.4, which fixes the issue.11hCVE-2024-583558.9 HIG21.4%
——6Cal.com (calcom/cal.diy) versions through 4.7.15 contain a stored cross-site scripting vulnerability. The single booking view (e.g., https://app.cal.com/booking/<id>) renders booking-question field labels via React's dangerouslySetInnerHTML without sanitizing or escaping user input. An attacker who can create an event type with a malicious booking-question label can inject arbitrary HTML/JavaScript that executes when a victim opens the crafted booking URL. The issue is fixed in v4.7.16.13hCVE-2024-583538.9 HIG22.0%
——7Cal.com (repository calcom/cal.diy) in versions <= 4.7.15 is vulnerable to cross-site scripting (XSS) on the publicly accessible single booking view (e.g., /booking/<id>). Booking question (form field) labels are rendered via React's dangerouslySetInnerHTML without proper input sanitization or CSP, so an attacker who can create an event type with a malicious booking question label can inject arbitrary HTML/JavaScript that executes when a victim visits the booking view URL. Self-hosted instances with open registration are particularly at risk. The issue is fixed in version 4.7.16.13hCVE-2026-328226.1 MED11.6%
——3dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, any unauthenticated attacker can place arbitrary HTML into flash notifications on public routes and rely on the frontend toast component to inject that content into the DOM with `innerHTML`. This creates a reflected DOM XSS that can be delivered with a crafted link to a public page such as `/docs`. Because the vulnerable JavaScript is loaded by the normal application layout, the issue is not limited to a special debug page or an isolated admin-only view.9dCVE-2026-54443—13.8%
——4Dashy is a self-hostable personal dashboard. From 1.9.4 until 3.2.0, the Dashy RSS Widget in src/components/Widgets/RssFeed.vue does not sanitize RSS item link values before rendering feed item titles and Read More links as anchor href attributes, allowing an attacker-controlled feed to provide a javascript: URI that executes when clicked in the Dashy origin. This issue is fixed in version 3.2.0.15dCVE-2026-598385.9 MED4.0%
