Koha

Koha is an open-source library-management system deployed across institutional and public libraries worldwide, presenting a focused but prominent attack surface centered on a single core product. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity and a frequent tendency to acquire public exploit code, reflecting the product's role in handling sensitive patron and collection data over the web. The exposure recurs persistently through application-layer weakness classes including cross-site scripting, SQL injection, path traversal, cross-site request forgery, and CSV-formula injection, which are characteristic of web-facing database-driven applications with complex input handling and administrative interfaces. Defenders should treat Koha deployments as high-priority for patch management, particularly where instances are internet-reachable or integrated with authentication systems; current exploitation activity and exposure counts are shown alongside this summary.
