CISA folds its own hard-won lessons into coordinated vulnerability disclosure guidance

Cybersecurity and Infrastructure Security Agency (CISA) and four allied cyber authorities published a guide telling software vendors how to build a coordinated vulnerability disclosure (CVD) program. Six days earlier, CISA published a blog post explaining how a security researcher had tried and failed, repeatedly, to report a serious problem to CISA itself. Read side by side, the two documents suggest the timing is deliberate.
