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-2021-24751 in the wild and no public exploit code.\n\nAffected product: Unknown GenerateBlocks. 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-2021-24751/ (Markdown: https://insights.sbomify.com/CVE-2021-24751/index.md)","id":"CVE-2021-24751","markdown":"https://insights.sbomify.com/CVE-2021-24751/index.md","name":"CVE-2021-24751","record":{"aliases":["GHSA-f648-43x4-7j96"],"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 the container block's tagName attribute, allowing attackers to execute code in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"generateblocks","vendor":"generateblocks"}],"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 GenerateBlocks WordPress plugin before 1.4.0 does not validate the generateblocks/container block's tagName attribute, which could allow users with a role as low as contributor to perform Cross-Site Scripting attacks.","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":"GenerateBlocks \u003c 1.4.0 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24751","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Multiple Plugins from CatchThemes - Unauthorised Plugin's Setting Change","id":"CVE-2021-24752"},"packages":[],"prev":{"headline":"WP Visitor Statistics (Real Time Traffic) \u003c 4.8 - Subscriber+ SQL Injection","id":"CVE-2021-24750"},"products":["GenerateBlocks"],"published":"2021-11-29","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":"Contributors can inject malicious scripts via the container block's tagName attribute, allowing attackers to execute code in victim browsers.","url":"https://insights.sbomify.com/CVE-2021-24751/"}
