Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-91107 in the wild and no public exploit code.\n\nAffected product: OS4ED openSIS-Classic. 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-2026-91107/ (Markdown: https://insights.sbomify.com/CVE-2026-91107/index.md)","id":"CVE-2026-91107","markdown":"https://insights.sbomify.com/CVE-2026-91107/index.md","name":"CVE-2026-91107","record":{"aliases":["GHSA-r588-8qfc-26mv"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"School Information System","requires_auth":"low_privilege","summary":"Authenticated teachers can reset passwords for arbitrary staff accounts via IDOR, enabling unauthorized access and privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fluid Attacks","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"openSIS Classic 9.3 allows an authenticated user with the built-in teacher role can select an arbitrary staff record through staff_id and cause the School Information update path to reset that selected account's password.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"openSIS Classic 9.3 - Insecure Direct Object Reference (IDOR)","id":"CVE-2026-91107","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Missing authorization in Alt Text AI – Automatically generate image alt text for SEO and accessibility","id":"CVE-2026-91108"},"packages":[],"prev":{"headline":"HP Linux Imaging and Printing (HPLIP) Software– Multiple Vulnerabilities","id":"CVE-2026-91106"},"products":["openSIS-Classic"],"published":"2026-10-05","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-06","vendors":["OS4ED"]},"summary":"Authenticated teachers can reset passwords for arbitrary staff accounts via IDOR, enabling unauthorized access and privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-91107/"}
