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-2026-1331 in the wild and no public exploit code.\n\nAffected product: AMASTAR Technology MeetingHub. 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-2026-1331/ (Markdown: https://insights.sbomify.com/CVE-2026-1331/index.md)","id":"CVE-2026-1331","markdown":"https://insights.sbomify.com/CVE-2026-1331/index.md","name":"CVE-2026-1331","record":{"aliases":["GHSA-j7qw-w5vf-rgxv"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MeetingHub web application","requires_auth":"none","summary":"Unauthenticated attackers can upload web shells to execute arbitrary code on the server.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"meetinghub_paperless_meetings","vendor":"hamastar"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"MeetingHub developed by HAMASTAR Technology has an Arbitrary File Upload vulnerability, allowing unauthenticated remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.","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":"AMASTAR Technology｜MeetingHub - Arbitrary File Upload","id":"CVE-2026-1331","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"HAMASTAR Technology｜MeetingHub - Missing Authentication","id":"CVE-2026-1332"},"packages":[],"prev":{"headline":"HAMASTAR Technology｜MeetingHub - Arbitrary File Read","id":"CVE-2026-1330"},"products":["MeetingHub"],"published":"2026-01-22","related":[{"cvss_score":9.3,"headline":"Hamastar MeetingHub Paperless Meetings - Unrestricted Upload of File with Dangerous Type","id":"CVE-2024-6117","kev_date_added":null,"published":"2024-08-05"},{"cvss_score":9.3,"headline":"Hamastar MeetingHub Paperless Meetings - Plaintext Storage of a Password","id":"CVE-2024-6118","kev_date_added":null,"published":"2024-08-05"},{"cvss_score":8.7,"headline":"HAMASTAR Technology｜MeetingHub - Arbitrary File Read","id":"CVE-2026-1330","kev_date_added":null,"published":"2026-01-22"},{"cvss_score":6.9,"headline":"HAMASTAR Technology｜MeetingHub - Missing Authentication","id":"CVE-2026-1332","kev_date_added":null,"published":"2026-01-22"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-01-22","vendors":["AMASTAR Technology"]},"summary":"Unauthenticated attackers can upload web shells to execute arbitrary code on the server.","url":"https://insights.sbomify.com/CVE-2026-1331/"}
