An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-63238 in the wild and no public exploit code.\n\nAffected product: Three Learning Koollab LMS. 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-2026-63238/ (Markdown: https://insights.sbomify.com/CVE-2026-63238/index.md)","id":"CVE-2026-63238","markdown":"https://insights.sbomify.com/CVE-2026-63238/index.md","name":"CVE-2026-63238","record":{"aliases":["GHSA-2g2j-fq65-5w72"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Koollab LMS","requires_auth":"none","summary":"Unauthenticated attackers can take over any account, including administrators, by exploiting a flaw in the 2FA validation endpoint.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CSA","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An authentication bypass vulnerability in Koollab LMS allowed an unauthenticated\nattacker to take over any account, including administrator accounts, by\nsupplying a valid user UUID without providing primary credentials via the 2FA\nvalidation endpoint.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Authentication bypass vulnerability","id":"CVE-2026-63238","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Hard-coded AWS IAM credentials vulnerability","id":"CVE-2026-63239"},"packages":[],"prev":{"headline":"TOTP two-factor authentication bypass vulnerability","id":"CVE-2026-63237"},"products":["Koollab LMS"],"published":"2026-07-29","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":"partial"},"state":"PUBLISHED","updated":"2026-07-29","vendors":["Three Learning"]},"summary":"Unauthenticated attackers can take over any account, including administrators, by exploiting a flaw in the 2FA validation endpoint.","url":"https://insights.sbomify.com/CVE-2026-63238/"}
