An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-41750 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nystudio107/craft-seomatic (Packagist): affected all versions; fixed in 3.4.11\n- nystudio107/craft-seomatic (Packagist): affected all versions; fixed in 3.4.11\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-2021-41750/ (Markdown: https://insights.sbomify.com/CVE-2021-41750/index.md)","id":"CVE-2021-41750","markdown":"https://insights.sbomify.com/CVE-2021-41750/index.md","name":"CVE-2021-41750","record":{"aliases":["GHSA-6hjc-m38h-7jhh"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Craft CMS plugin","requires_auth":"none","summary":"Remote attackers can inject arbitrary web script via crafted GET parameters in the SEOmatic plugin for Craft CMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"seomatic","vendor":"nystudio107"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"A cross-site scripting (XSS) vulnerability in the SEOmatic plugin 3.4.10 for Craft CMS 3 allows remote attackers to inject arbitrary web script via a GET to /index.php?action=seomatic/file/seo-file-link with url parameter containing the base64 encoded URL of a malicious web page / file and fileName parameter containing an arbitrary filename with the intended content-type to be rendered in the user's browser as the extension.","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":"Cross-site Scripting in SEOmatic plugin","id":"CVE-2021-41750","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-41751"},"packages":[{"ecosystem":"Packagist","fixed":["3.4.11"],"introduced":["0"],"last_affected":[],"package":"nystudio107/craft-seomatic","purl":null,"source":"GHSA-6hjc-m38h-7jhh"},{"ecosystem":"Packagist","fixed":["3.4.11"],"introduced":["0"],"last_affected":[],"package":"nystudio107/craft-seomatic","purl":"pkg:composer/nystudio107/craft-seomatic","source":"GHSA-6hjc-m38h-7jhh"}],"prev":{"headline":"Code Injection in SEOmatic","id":"CVE-2021-41749"},"products":["n/a"],"published":"2022-06-12","related":[{"cvss_score":9.8,"headline":"Code Injection in SEOmatic","id":"CVE-2021-41749","kev_date_added":null,"published":"2022-06-12"},{"cvss_score":9.8,"headline":"Server-side Template Injection in nystudio107/craft-seomatic","id":"CVE-2021-44618","kev_date_added":null,"published":"2022-03-11"},{"cvss_score":7.5,"headline":"SEOmatic for CraftCMS allows Server-Side Template Injection","id":"CVE-2020-12790","kev_date_added":null,"published":"2020-05-11"},{"cvss_score":7.5,"headline":"SEOmatic plugin for Craft CMS SSTI Vulnerability","id":"CVE-2018-14716","kev_date_added":null,"published":"2018-08-06"}],"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":"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":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can inject arbitrary web script via crafted GET parameters in the SEOmatic plugin for Craft CMS.","url":"https://insights.sbomify.com/CVE-2021-41750/"}
