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-2021-24637 in the wild and no public exploit code.\n\nAffected product: Unknown Fonts Plugin | Google Fonts Typography. 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-2021-24637/ (Markdown: https://insights.sbomify.com/CVE-2021-24637/index.md)","id":"CVE-2021-24637","markdown":"https://insights.sbomify.com/CVE-2021-24637/index.md","name":"CVE-2021-24637","record":{"aliases":["GHSA-x8c7-9c7c-54qw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Contributors can inject malicious scripts via unescaped block settings in the Google Fonts Typography plugin, leading to stored XSS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"fonts","vendor":"fontsplugin"}],"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 Google Fonts Typography WordPress plugin before 3.0.3 does not escape and sanitise some of its block settings, allowing users with as role as low as Contributor to perform Stored Cross-Site Scripting attacks via blockType (combined with content), align, color, variant and fontID argument of a Gutenberg block.","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":"Fonts Plugin \u003c 3.0.3 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24637","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"OMGF \u003c 4.5.4 - Unauthenticated Path Traversal in REST API","id":"CVE-2021-24638"},"packages":[],"prev":{"headline":"Print My Blog \u003c 3.4.2 - Plugin Deactivation via CSRF","id":"CVE-2021-24636"},"products":["Fonts Plugin | Google Fonts Typography"],"published":"2021-09-20","related":[{"cvss_score":7.1,"headline":"WordPress Fonts plugin \u003c= 3.7.7 - Cross Site Request Forgery (CSRF) to Stored XSSvulnerability","id":"CVE-2024-43301","kev_date_added":null,"published":"2024-08-26"},{"cvss_score":4.3,"headline":"WordPress Fonts plugin \u003c= 3.7.7 - Broken Access Control vulnerability","id":"CVE-2024-43302","kev_date_added":null,"published":"2024-11-01"}],"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":"Contributors can inject malicious scripts via unescaped block settings in the Google Fonts Typography plugin, leading to stored XSS.","url":"https://insights.sbomify.com/CVE-2021-24637/"}
