EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.1 under NVD CVSS v3. EPSS exploit probability: 0.4% (30th percentile of EPSS-scored CVEs). 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).

Silverstripe Form Capture provides a method to capture simple silverstripe forms and an admin interface for users. Starting in version 0.2.0 and prior to versions 1.0.2, 1.1.0, 2.2.5, and 3.1.1, improper escaping when presenting stored form submissions allowed for an attacker to perform a Cross-Site Scripting attack. The vulnerability was initially patched in version 1.0.2, and version 1.1.0 includes this patch. The bug was then accidentally re-introduced during a merge error, and has been re-patched in versions 2.2.5 and 3.1.1. There are no known workarounds for this vulnerability.
