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-2021-24782 in the wild and no public exploit code.\n\nAffected product: Unknown Flex Local Fonts. 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-2021-24782/ (Markdown: https://insights.sbomify.com/CVE-2021-24782/index.md)","id":"CVE-2021-24782","markdown":"https://insights.sbomify.com/CVE-2021-24782/index.md","name":"CVE-2021-24782","record":{"aliases":["GHSA-fp4x-73jw-phj9"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"High-privilege users can inject malicious scripts via the font class name field in the Flex Local Fonts WordPress plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"flex_local_fonts","vendor":"flex_local_fonts_project"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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 Flex Local Fonts WordPress plugin through 1.0.0 does not escape the Class Name field when adding a font, which could allow hight privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Flex Local Fonts \u003c= 1.0.0 - Admin+ Stored Cross-Site-Scripting","id":"CVE-2021-24782","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Post Expirator \u003c 2.6.0 - Contributor+ Arbitrary Post Schedule Deletion","id":"CVE-2021-24783"},"packages":[],"prev":{"headline":"Image Source Control \u003c 2.3.1 - Contributor+ Arbitrary Post Meta Value Change","id":"CVE-2021-24781"},"products":["Flex Local Fonts"],"published":"2021-12-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"High-privilege users can inject malicious scripts via the font class name field in the Flex Local Fonts WordPress plugin.","url":"https://insights.sbomify.com/CVE-2021-24782/"}
