Smart Wing CMS, published on 17 Aug 2022. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-26639 in the wild and no public exploit code.\n\nAffected product: WISA corp. Smart Wing CMS. 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-2021-26639/ (Markdown: https://insights.sbomify.com/CVE-2021-26639/index.md)","id":"CVE-2021-26639","markdown":"https://insights.sbomify.com/CVE-2021-26639/index.md","name":"CVE-2021-26639","record":{"aliases":["GHSA-6fq5-356h-9jrc"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WISA Smart Wing CMS","requires_auth":"low_privilege","summary":"Remote attackers can leak all server files without authentication due to lack of input validation in WISA Smart Wing CMS.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"smart_wing_cms","vendor":"wisa"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"This vulnerability is caused by the lack of validation of input values for specific functions if WISA Smart Wing CMS.
