Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-26378 exists.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-26378/ (Markdown: https://insights.sbomify.com/CVE-2026-26378/index.md)","id":"CVE-2026-26378","markdown":"https://insights.sbomify.com/CVE-2026-26378/index.md","name":"CVE-2026-26378","record":{"aliases":["GHSA-j9m8-fw2w-frcq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Koha ILS","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code via XSS in Koha's invoice file upload feature, requiring an upgrade to secure the library system.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"koha","vendor":"koha"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross Site Scripting vulnerability in Koha 25.11 and before allows a remote attacker to execute arbitrary code via file upload function in Invoice features","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Cross-site scripting in n/a","id":"CVE-2026-26378","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Server-side request forgery in n/a","id":"CVE-2026-26379"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2026-26377"},"products":["n/a"],"published":"2026-06-03","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2014-1924","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2014-1925","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2015-4633","kev_date_added":null,"published":"2018-10-18"},{"cvss_score":9.6,"headline":"Command injection in n/a","id":"CVE-2024-28739","kev_date_added":null,"published":"2024-08-06"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2024-24337","kev_date_added":null,"published":"2024-02-12"},{"cvss_score":8.8,"headline":"KOHA Library System version 16.11.x (up until 16.11.13) and 17.05.x (up until 17.05.05) contains a Cross Site Request Forgery (CSRF) vulnera","id":"CVE-2018-1000669","kev_date_added":null,"published":"2018-09-06"},{"cvss_score":8.8,"headline":"Cross-site scripting in n/a","id":"CVE-2015-4639","kev_date_added":null,"published":"2017-07-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-04","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via XSS in Koha's invoice file upload feature, requiring an upgrade to secure the library system.","url":"https://insights.sbomify.com/CVE-2026-26378/"}
