CVE-2025-71430: Frappe before 15.91.1 Stored XSS via Leaderboard User Names

Noroxi assessment

Priority: Monitor (action score 20/100)

  • 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: 0.16% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No special conditions are required; it is repeatable.
  • Fixed version: frappe frappe 14.99.10, 15.91.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to frappe frappe 14.99.10, 15.91.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Frappe before 14.99.10 and 15.x before 15.91.1 contains a stored cross-site scripting vulnerability in the leaderboard page because user names are rendered without proper neutralization. Authenticated attackers can set a crafted user name that executes arbitrary JavaScript in the browsers of other users who view the leaderboard.

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.
