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-2021-24587 in the wild and no public exploit code.\n\nAffected product: Unknown Splash Header. 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-2021-24587/ (Markdown: https://insights.sbomify.com/CVE-2021-24587/index.md)","id":"CVE-2021-24587","markdown":"https://insights.sbomify.com/CVE-2021-24587/index.md","name":"CVE-2021-24587","record":{"aliases":["GHSA-vm9v-hfwf-qw4q"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can inject malicious scripts into the admin dashboard via unsanitized settings in the Splash Header plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"splash_header","vendor":"zeesweb"}],"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 Splash Header WordPress plugin before 1.20.8 doesn't sanitise and escape some of its settings while outputting them in the admin dashboard, 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":"Splash Header \u003c 1.20.8 - Authenticated Stored Cross-Site Scripting (XSS)","id":"CVE-2021-24587","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"SMS Alert Order Notifications – WooCommerce \u003c 3.4.7 Authenticated Cross Site Scripting","id":"CVE-2021-24588"},"packages":[],"prev":{"headline":"Per Page Add to Head \u003c 1.4.4 - CSRF to Stored XSS","id":"CVE-2021-24586"},"products":["Splash Header"],"published":"2021-09-20","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 attackers can inject malicious scripts into the admin dashboard via unsanitized settings in the Splash Header plugin.","url":"https://insights.sbomify.com/CVE-2021-24587/"}
