{"id":"CVE-2026-72610","state":"PUBLISHED","title":"Koha Community Koha - Stored SQL Injection via Patron lang Field in Issue Slip Generation","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.","publishedAt":"2026-08-11T11:22:47.134Z","updatedAt":"2026-08-11T12:02:46.877Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","source":"TuranSec"},"assigner":"TuranSec","products":["Koha Community Koha"],"affected":[{"vendor":"Koha Community","product":"Koha","versions":[{"version":"0","status":"affected","lessThan":"24.11.18","versionType":"custom"},{"version":"25.05.0","status":"affected","lessThan":"25.05.13","versionType":"custom"},{"version":"25.11.0","status":"affected","lessThan":"25.11.07","versionType":"custom"},{"version":"26.05.0","status":"affected","lessThan":"26.05.02","versionType":"custom"}]}],"references":["https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42866","https://koha-community.org/"],"weaknesses":["CWE-89"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/72xxx/CVE-2026-72610.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-72610","state":"PUBLISHED","datePublished":"2026-08-11T11:22:47.134Z","dateUpdated":"2026-08-11T12:02:46.877Z","assignerShortName":"TuranSec","assignerOrgId":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c","dateReserved":"2026-08-10T10:33:03.258Z"},"containers":{"cna":{"title":"Koha Community Koha - Stored SQL Injection via Patron lang Field in Issue Slip Generation","descriptions":[{"lang":"en","value":"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.
