The Canvas breach exposed higher Ed's third-party identity blind spot

Canvas LMS breach at 8,809 institutions exposed 275 million records through a trust boundary failure in the free-tier account system; a second breach by the same attacker within 24 hours of the vendor's 'resolved' declaration reveals ongoing systemic vulnerability in tiered SaaS architecture. If you sell identity, access control, or breach response tools to education or any vertical running tiered SaaS, Canvas just proved that vendor 'containment' claims mean nothing—your customer's security is only as good as the vendor's weakest account tier, and that tier is connected to everything. Call every education IT director this week and ask which free or low-verification account tiers are plugged into their critical systems.
