Patch & Detection Intelligence · 3 sources · Updated 4mo ago · First seen Apr 21, 2026

Spring published multiple security advisories covering several widely used components, including Spring Cloud Gateway, Spring Security, Spring Authorization Server, Spring Framework, and a critical update for Spring Boot. The Canadian Centre for Cyber Security said the advisories were released between April 9 and April 23 and identified affected version ranges across these product lines, with Spring Boot fixes specifically issued for the 4.0.x, 3.5.x, 3.4.x, 3.3.x, and 2.7.x release branches.
Canadian authorities urged organizations to review the referenced Spring advisories and apply the vendor updates for all impacted deployments. The notices describe the issue as a patching and vulnerability-management matter rather than confirmed active exploitation, but they emphasize that administrators should promptly update affected Spring environments to the patched versions listed by the vendor.
