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-2020-11064 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms (Packagist): affected from 10.0.0; fixed in 10.4.2\n- typo3/cms (Packagist): affected from 10.0.0; fixed in 10.4.2\n- typo3/cms (Packagist): affected from 9.0.0; fixed in 9.5.17\n- typo3/cms (Packagist): affected from 9.0.0; fixed in 9.5.17\n- typo3 (Bitnami): affected from 9.0.0; fixed in 9.5.17, 10.4.2\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.2\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.2\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.17\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.17\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-2020-11064/ (Markdown: https://insights.sbomify.com/CVE-2020-11064/index.md)","id":"CVE-2020-11064","markdown":"https://insights.sbomify.com/CVE-2020-11064/index.md","name":"CVE-2020-11064","record":{"aliases":["BIT-typo3-2020-11064","GHSA-43gj-mj2w-wh46"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"low_privilege","summary":"An authenticated backend user can inject malicious scripts via HTML placeholder attributes, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"typo3","vendor":"typo3"}],"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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In TYPO3 CMS greater than or equal to 9.0.0 and less than 9.5.17 and greater than or equal to 10.0.0 and less than 10.4.2, it has been discovered that HTML placeholder attributes containing data of other database records are vulnerable to cross-site scripting.
