Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-63239 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-2026-63239/ (Markdown: https://insights.sbomify.com/CVE-2026-63239/index.md)","id":"CVE-2026-63239","markdown":"https://insights.sbomify.com/CVE-2026-63239/index.md","name":"CVE-2026-63239","record":{"aliases":["GHSA-4fpv-9r28-747f"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Koollab LMS","requires_auth":"low_privilege","summary":"Hard-coded AWS credentials in Koollab LMS allow attackers to access S3 buckets and SQS queues, exposing data and enabling malicious actions.","user_interaction":"required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CSA","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","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-798","name":"Use of Hard-coded Credentials"}],"description":"A hard-coded AWS IAM credentials vulnerability\nin Koollab LMS allowed\nan attacker to access shared multi-tenant S3 buckets and SQS queues, exposing\nsensitive data and enabling malicious content injection, job manipulation, or\nemail interception.","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":"Hard-coded AWS IAM credentials vulnerability","id":"CVE-2026-63239","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure vulnerability","id":"CVE-2026-63240"},"packages":[],"prev":{"headline":"Authentication bypass vulnerability","id":"CVE-2026-63238"},"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":"Hard-coded AWS credentials in Koollab LMS allow attackers to access S3 buckets and SQS queues, exposing data and enabling malicious actions.","url":"https://insights.sbomify.com/CVE-2026-63239/"}
