CVE-2023-28851

19
FAUCET Score

CVE-2023-28851 is a Cross-Site Scripting (XSS) vulnerability affecting Silverstripe Form Capture versions 0.2.0 through 1.0.1, 1.0.3 through 2.2.4, and 3.0.0 through 3.1.0. This medium-severity flaw (CVSS 5.4) arises from improper escaping of stored form submissions, allowing an authenticated attacker to inject malicious scripts via user interaction. While there are no known active exploits, public exploit code, or significant community discussion, organizations using affected versions should prioritize patching to versions 1.0.2, 1.1.0, 2.2.5, or 3.1.1 to mitigate this risk.
