CVE-2026-6428 MEDIUM PATCH This Month

SQL injection in Koha's reports/catalogue_out.pl grants authenticated staff with the Reports module flag full read access to the Koha MariaDB database, including borrower password hashes, 2FA secrets, API keys, session tokens, and patron PII. The vulnerability traces to a 2008 commit and was overlooked when CVE-2015-4633 patched the same injection class in sibling files. A working single-request proof-of-concept using EXTRACTVALUE error-based extraction has been publicly disclosed; no CISA KEV listing has been confirmed at time of analysis, but the low exploitation barrier for credentialed staff makes this a high-priority remediation.
