CVE-2026-52781: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in opf openprojectCVE-2026-52781 0 OpenProject is open-source, web-based project management software. Prior to 17.3.3 and 17.4.1, the HTML sanitizer grants <macro> elements unrestricted data-* attributes via :data wildcard. An attacker injects data-controller="poll-for-changes" into a work package description, causing Stimulus.js to mount a controller that fetches an attacker-uploaded attachment and passes it to renderStreamMessage(). This executes arbitrary Turbo Stream actions — including redirect_to — in every victim's authenticated browser session, redirecting them to an attacker-controlled server. This vulnerability is fixed in 17.3.3 and 17.4.1. Join the discussion | CVE Database V5 | 06/26/2026, 19:00:10 UTC Added: 06/26/2026, 19:37:15 UTC |
