HighCVSS 8.8 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.42% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No special conditions are required; it is repeatable.
  • Fixed version: pretix pretix 2026.3.4, 2026.4.4, 2026.5.2.

Low priority for now. Upgrade to pretix pretix 2026.3.4, 2026.4.4, 2026.5.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Malicious HTML content contained in the layout specification of a PDF ticket or badge layout was executed when the PDF editor is opened in the browser. This could allow one backend user to inject JavaScript into the browser context of another backend user. Due to requirements of the PDF rendering and editing libraries used, this is one of the few pages in our backend that do not have a strong Content-Security-Policy that would render this capability useless for most scenarios.
