Formwork through 2.3.14 contains a stored cross-site scripting vulnerability in visit tracking that records the Referer header host unescaped. Unauthenticated attackers can craft malicious Referer headers to inject markup that executes in administrator browsers when viewing the Statistics panel.
CVE-2026-82451
This medium-severity CVE scores 6.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
