{"schema":"threatline.record/2","record":{"id":"CVE-2026-105106","aliases":[],"summary":"Koha authenticated OS command injection in tools/scheduler.pl via the jobid parameter when deleting a scheduled task","details":"Koha is vulnerable to OS command injection in the Task Scheduler deletion path. 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.","categories":["Unclassified"],"product":"Koha","vendor":"Koha Community","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105106","source_modified_at":"2026-10-14T17:56:36.316Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Koha","vendor":"Koha Community","versions":[{"status":"affected","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"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105106","source_modified_at":"2026-10-14T17:56:36.316Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Koha","ecosystem":null},"version":"24.11.00","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105106","source_modified_at":"2026-10-14T17:56:36.316Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Koha","ecosystem":null},"version":"24.11.20","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105106","source_modified_at":"2026-10-14T17:56:36.316Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Koha","ecosystem":null},"version":"25.05.15","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105106","source_modified_at":"2026-10-14T17:56:36.316Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Koha","ecosystem":null},"version":"25.11.09","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105106","source_modified_at":"2026-10-14T17:56:36.316Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Koha","ecosystem":null},"version":"26.05.04","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.01613,"percentile":0.75793,"score_date":"2026-10-23"},"published_at":"2026-10-14T07:23:03.069Z","modified_at":"2026-10-14T17:56:36.316Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105106","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T17:56:36.316Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105106","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42674","tags":["exploit"]},{"source":"CVE List","url":"https://download.koha-community.org/"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2025-30076","tags":["related"]},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2024-28739","tags":["related"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-14T17:55:56.921737Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T17:56:36.316Z","content_hash":"a7a9879e4407f946ee2d5a7b43a531f492c178f8a39c4b42e895d0c21414e64d"}}
