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-2021-24545 in the wild and no public exploit code.\n\nAffected product: Unknown WP HTML Author Bio. 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-2021-24545/ (Markdown: https://insights.sbomify.com/CVE-2021-24545/index.md)","id":"CVE-2021-24545","markdown":"https://insights.sbomify.com/CVE-2021-24545/index.md","name":"CVE-2021-24545","record":{"aliases":["GHSA-xv7x-q4ch-37fx"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authors can inject malicious JavaScript into their bio, leading to XSS and potential privilege escalation when admins view posts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"wp_html_author_bio","vendor":"wp_html_author_bio_project"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","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":"The WP HTML Author Bio WordPress plugin through 1.2.0 does not sanitise the HTML allowed in the Bio of users, allowing them to use malicious JavaScript code, which will be executed when anyone visit a post in the frontend made by such user.
