Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-48203 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- clickstorm/cs-seo (Packagist): affected from 6.3.0; fixed in 6.8.0\n- clickstorm/cs-seo (Packagist): affected from 6.3.0; fixed in 6.8.0\n- clickstorm/cs-seo (Packagist): affected from 7.0.0; fixed in 7.5.0\n- clickstorm/cs-seo (Packagist): affected from 7.0.0; fixed in 7.5.0\n- clickstorm/cs-seo (Packagist): affected from 8.0.0; fixed in 8.4.0\n- clickstorm/cs-seo (Packagist): affected from 8.0.0; fixed in 8.4.0\n- clickstorm/cs-seo (Packagist): affected from 9.0.0; fixed in 9.3.0\n- clickstorm/cs-seo (Packagist): affected from 9.0.0; fixed in 9.3.0\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-2025-48203/ (Markdown: https://insights.sbomify.com/CVE-2025-48203/index.md)","id":"CVE-2025-48203","markdown":"https://insights.sbomify.com/CVE-2025-48203/index.md","name":"CVE-2025-48203","record":{"aliases":["GHSA-6p8w-pc35-mqv8"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 SEO extension","requires_auth":"low_privilege","summary":"Cross-site scripting vulnerability in the cs_seo extension for TYPO3 allows attackers to inject malicious scripts.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/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 cs_seo extension through 9.2.0 for TYPO3 allows XSS.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"[clickstorm] SEO (cs_seo) TYPO3 extension Cross-site Scripting (XSS) vulnerability","id":"CVE-2025-48203","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2025"},"n_packages":8,"n_references":1,"next":{"headline":"The Backup Plus extension for TYPO3 (ns_backup) allows command injections","id":"CVE-2025-48204"},"packages":[{"ecosystem":"Packagist","fixed":["6.8.0"],"introduced":["6.3.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":null,"source":"GHSA-6p8w-pc35-mqv8"},{"ecosystem":"Packagist","fixed":["6.8.0"],"introduced":["6.3.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":"pkg:composer/clickstorm/cs-seo","source":"GHSA-6p8w-pc35-mqv8"},{"ecosystem":"Packagist","fixed":["7.5.0"],"introduced":["7.0.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":null,"source":"GHSA-6p8w-pc35-mqv8"},{"ecosystem":"Packagist","fixed":["7.5.0"],"introduced":["7.0.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":"pkg:composer/clickstorm/cs-seo","source":"GHSA-6p8w-pc35-mqv8"},{"ecosystem":"Packagist","fixed":["8.4.0"],"introduced":["8.0.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":null,"source":"GHSA-6p8w-pc35-mqv8"},{"ecosystem":"Packagist","fixed":["8.4.0"],"introduced":["8.0.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":"pkg:composer/clickstorm/cs-seo","source":"GHSA-6p8w-pc35-mqv8"},{"ecosystem":"Packagist","fixed":["9.3.0"],"introduced":["9.0.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":null,"source":"GHSA-6p8w-pc35-mqv8"},{"ecosystem":"Packagist","fixed":["9.3.0"],"introduced":["9.0.0"],"last_affected":[],"package":"clickstorm/cs-seo","purl":"pkg:composer/clickstorm/cs-seo","source":"GHSA-6p8w-pc35-mqv8"}],"prev":{"headline":"The femanager TYPO3 extension allows Insecure Direct Object Reference","id":"CVE-2025-48202"},"products":["cs seo extension"],"published":"2025-05-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-21","vendors":["TYPO3"]},"summary":"Cross-site scripting vulnerability in the cs_seo extension for TYPO3 allows attackers to inject malicious scripts.","url":"https://insights.sbomify.com/CVE-2025-48203/"}
