{"cve":"CVE-2025-13742","nvd":{"published":"2025-11-27T11:15:47.760","modified":"2026-10-19T13:10:00.110","status":"Analyzed","description":"Emails sent by pretix can utilize placeholders that will be filled with customer data. For example, when {name} is used in an email template, it will be replaced with the buyer's name for the final email. If the name of the attendee contained HTML or Markdown formatting, this was rendered as HTML in the resulting email. This way, a user could inject links or other formatted text through a maliciously formatted name. Since pretix applies a strict allow list approach to allowed HTML tags, this could not be abused for XSS or similarly dangerous attack chains. However, it can be used to manipulate emails in a way that makes user-provided content appear in a trustworthy and credible way, which can be abused for phishing.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:L/VA:L/SC:N/SI:L/SA:L/E:U","score":2.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-116"],"references":["https://pretix.eu/about/en/blog/20251126-release-2025-9-1/"],"products":["pretix:pretix"],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-13742","score":0.00183,"percentile":0.07805,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-2mm6-624x-fqrr","url":"https://osv.dev/vulnerability/GHSA-2mm6-624x-fqrr","summary":"pretix has Email Content Injection Through Maliciously Formatted Names","modified":"2026-06-09T16:26:06.058412408Z","packages":[{"ecosystem":"PyPI","name":"pretix","purl":"pkg:pypi/pretix","ranges":[">=1.0.0 <2025.7.3"],"fixed":["2025.7.3"]},{"ecosystem":"PyPI","name":"pretix","purl":"pkg:pypi/pretix","ranges":[">=2025.8.0 <2025.8.2"],"fixed":["2025.8.2"]},{"ecosystem":"PyPI","name":"pretix","purl":"pkg:pypi/pretix","ranges":[">=2025.9.0 <2025.9.2"],"fixed":["2025.9.2"]}]},{"id":"PYSEC-2025-154","url":"https://osv.dev/vulnerability/PYSEC-2025-154","summary":"","modified":"2026-06-10T17:01:37.478664702Z","packages":[{"ecosystem":"PyPI","name":"pretix","purl":"pkg:pypi/pretix","ranges":[">=1.0.0 <2025.7.2"],"fixed":["2025.7.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
