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-2021-24518 in the wild and no public exploit code.\n\nAffected product: Unknown WPFront Notification Bar. 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-2021-24518/ (Markdown: https://insights.sbomify.com/CVE-2021-24518/index.md)","id":"CVE-2021-24518","markdown":"https://insights.sbomify.com/CVE-2021-24518/index.md","name":"CVE-2021-24518","record":{"aliases":["GHSA-xq6f-vw46-2gmq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Authenticated admins can inject stored XSS payloads via the Custom CSS setting in the WPFront Notification Bar plugin, potentially compromising site visitors.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"notification_bar","vendor":"wpfront"}],"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 WPFront Notification Bar WordPress plugin before 2.0.0.07176 does not sanitise or escape its Custom CSS setting, allowing high privilege users such as admin to set XSS payload in it even when the unfiltered_html capability is disallowed, leading to an authenticated Stored Cross-Site Scripting issue","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":"WPFront Notification Bar \u003c 2.0.0.07176 - Authenticated Stored XSS","id":"CVE-2021-24518","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Vik Rent Car \u003c 1.1.10 - Authenticated Stored Cross-Site Scripting (XSS)","id":"CVE-2021-24519"},"packages":[],"prev":{"headline":"Stop Spammers Security \u003c 2021.18 - Authenticated Stored XSS","id":"CVE-2021-24517"},"products":["WPFront Notification Bar"],"published":"2021-08-16","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":"Authenticated admins can inject stored XSS payloads via the Custom CSS setting in the WPFront Notification Bar plugin, potentially compromising site visitors.","url":"https://insights.sbomify.com/CVE-2021-24518/"}
