CVE-2026-125729
No CVSS score yet. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.
Plack::Middleware::CSP versions before 0.03 for Perl send the Content Security Policy under the wrong header name, so browsers never enforce it.
The call method sets the policy in a response header named "content-security-protocol" instead of "Content-Security-Policy". Browsers ignore that header.
Any cross-site scripting flaw in the wrapped application can run scripts the policy was meant to block.
