An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-26628 in the wild and no public exploit code.\n\nAffected product: No Vendor Information MaxBoard. 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-2021-26628/ (Markdown: https://insights.sbomify.com/CVE-2021-26628/index.md)","id":"CVE-2021-26628","markdown":"https://insights.sbomify.com/CVE-2021-26628/index.md","name":"CVE-2021-26628","record":{"aliases":["GHSA-4hqp-qgvw-892g"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MaxBoard web application","requires_auth":"none","summary":"Attackers can exploit XSS to steal admin privileges and upload arbitrary files disguised as images in MaxBoard.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"maxboard","vendor":"maxb"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Insufficient script validation of the admin page enables XSS, which causes unauthorized users to steal admin privileges.
