An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-4049 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- wordpress (Bitnami): affected from 3.7.0; fixed in 3.7.34, 3.8.34, 3.9.32, 4.0.31, 4.1.31, 4.2.28, 4.3.24, 4.4.23, 4.5.22, 4.6.19, 4.7.18, 4.8.14, 4.9.15, 5.0.10, 5.1.6, 5.2.7, 5.3.4, 5.4.2\n- wordpress-multisite (Bitnami): affected from 3.7.0; fixed in 3.7.34, 3.8.34, 3.9.32, 4.0.31, 4.1.31, 4.2.28, 4.3.24, 4.4.23, 4.5.22, 4.6.19, 4.7.18, 4.8.14, 4.9.15, 5.0.10, 5.1.6, 5.2.7, 5.3.4, 5.4.2\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-2020-4049/ (Markdown: https://insights.sbomify.com/CVE-2020-4049/index.md)","id":"CVE-2020-4049","markdown":"https://insights.sbomify.com/CVE-2020-4049/index.md","name":"CVE-2020-4049","record":{"aliases":["BIT-wordpress-2020-4049","BIT-wordpress-multisite-2020-4049","DEBIAN-CVE-2020-4049","GHSA-87h4-phjv-rm6p","UBUNTU-CVE-2020-4049"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress CMS","requires_auth":"high_privilege","summary":"Authenticated administrators can trigger JavaScript execution via crafted theme folder names during upload, requiring an upgrade to patched versions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"wordpress","vendor":"wordpress"}],"cvss":{"score":2.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"In affected versions of WordPress, when uploading themes, the name of the theme folder can be crafted in a way that could lead to JavaScript execution in /wp-admin on the themes page.
