CVE-2026-72608: Koha Community Koha

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

A stored SQL injection vulnerability in Koha through 24.11.17, 25.05.12, 25.11.06, and 26.05.01 allows authenticated staff with the tools => label_creator permission to execute arbitrary SQL via the image_name field of a patron card layout. The image_name value is stored verbatim in the layout XML and later concatenated raw into a SQL query in patroncards/create-pdf.pl when a patron card batch is printed. An attacker can read the entire Koha database including patron PII and staff bcrypt password hashes via error-based or time-based blind injection.
