What is CVE-2026-25764?

OpenProject, a widely used open-source project management software, contains an HTML injection vulnerability in its time tracking feature. This issue arises because the application fails to properly escape HTML tags, allowing an attacker with administrator privileges to craft a work package name containing malicious HTML. When this crafted name is added to the time tracking section, it can lead to potentially harmful consequences. The vulnerability has been addressed in versions 16.6.7 and 17.0.3, emphasizing the importance of updating to these secure versions to mitigate risk.
