EPSS

• CVE-2024-8113: 0.32% estimated exploitation activity in the next 30 days; percentile 25.53 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Stored XSS in organizer and event settings of pretix up to 2024.7.0 allows malicious event organizers to inject HTML tags into e-mail previews on settings page. The default Content Security Policy of pretix prevents execution of attacker-provided scripts, making exploitation unlikely. However, combined with a CSP bypass (which is not currently known) the vulnerability could be used to impersonate other organizers or staff users.

# Patch Next advisory brief: CVE-2024-8113

Advisory: pretix Stored Cross-site Scripting vulnerability
IDs: CVE-2024-8113, GHSA-45rp-q25w-4426
Record: https://patchnext.com/advisories/cve-2024-8113 (revision 3, source checked 26 Oct 2026, 13:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: pretix 2024.7.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI pretix: affected < 2024.7.1; fixed in 2024.7.1

## Suggested inspection (read-only)
- `python -m pip show pretix`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on pretix.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
