The tools/scheduler.pl handler accepts the jobid request parameter for op=cud-delete and passes it to C4::Scheduler::remove_at_job without validating it. Schedule::At::remove substitutes the supplied job ID into an atrm command string without quoting or escaping it and executes the command through a single-argument system() call, which invokes the shell. An authenticated staff user with the tools => schedule_tasks permission can therefore execute arbitrary operating-system commands as the Koha web/application user by supplying shell metacharacters in jobid. The issue is fixed in Koha 24.11.20, 25.05.15, 25.11.09, and 26.05.04, and in the 26.11 development branch."}],"affected":[{"source":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c","affectedData":[{"vendor":"Koha Community","product":"Koha","defaultStatus":"unaffected","versions":[{"version":"0","lessThan":"24.11.00","versionType":"custom","status":"affected"},{"version":"24.11.00","lessThan":"24.11.20","versionType":"custom","status":"affected"},{"version":"25.05.00","lessThan":"25.05.15","versionType":"custom","status":"affected"},{"version":"25.11.00","lessThan":"25.11.09","versionType":"custom","status":"affected"},{"version":"26.05.00","lessThan":"26.05.04","versionType":"custom","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-14T17:55:56.921737Z","id":"CVE-2026-105106","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c","type":"Secondary","description":[{"lang":"en","value":"CWE-78"}]}],"references":[{"url":"https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42674","source":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c"},{"url":"https://download.koha-community.org/","source":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c"},{"url":"https://www.cve.org/CVERecord?id=CVE-2024-28739","source":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c"},{"url":"https://www.cve.org/CVERecord?id=CVE-2025-30076","source":"309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c"},{"url":"https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42674","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}}]}
