Apereo

Apereo develops open-source software serving higher-education and institutional identity and access management, with a focused portfolio anchored by products such as OpenCast, Central Authentication Service, phpCAS, and calendar and WebDAV engines that are embedded across academic infrastructure. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity and a moderate tendency toward public exploit availability, reflecting the authentication-critical and data-handling roles these systems play in campus networks. The exposure recurs across this product line through weakness classes including improper authentication, exposure of sensitive information, injection flaws, cross-site scripting, and XML external entity vulnerabilities—patterns characteristic of web-facing identity and media-management systems handling institutional credentials and student records. Defenders should prioritize patching within the authentication and directory-facing tier and audit integration points where these systems interface with institutional repositories and student-information systems. Current severity, exploitation, and exposure counts are shown alongside this summary.
