CyberRota Analysis
AI-GeneratedKoha versions up to 26.05.01 are vulnerable to a stored SQL injection that allows authenticated staff with specific permissions to execute time-based denial of service attacks by injecting SQL payloads into a patron language field. This vulnerability can lead to performance degradation during the printing of issue slips, as the attack scales with the SLEEP value and the number of slip-news rows. Organizations using Koha, particularly those with staff who have edit permissions for borrower records, should prioritize remediation to mitigate potential service disruptions.

Original NVD Description
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 borrowers => edit_borrowers permission to cause a time-based denial of service by storing a SQL payload in a patron lang field. The value is concatenated raw into a subquery in Koha::AdditionalContents->search_for_display when an issue slip is printed for the affected patron. The 25-character column length limits exploitation to timing attacks; data extraction is not practical. The stored payload executes on each subsequent issue-slip print, scaling linearly with the SLEEP value and the number of slip-news rows.
