An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-41749 exists.\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-2021-41749/ (Markdown: https://insights.sbomify.com/CVE-2021-41749/index.md)","id":"CVE-2021-41749","markdown":"https://insights.sbomify.com/CVE-2021-41749/index.md","name":"CVE-2021-41749","record":{"aliases":["GHSA-g7xr-v82w-qggq"],"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":"Unauthenticated attackers can achieve remote code execution via Server-Side Template Injection in the SEOmatic plugin for Craft CMS.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"seomatic","vendor":"nystudio107"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"In the SEOmatic plugin up to 3.4.11 for Craft CMS 3, it is possible for unauthenticated attackers to perform a Server-Side Template Injection, allowing for remote code execution.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-41749.yaml","stars":null,"title":"CraftCMS SEOmatic - Server-Side Template Injection"}],"tier":"weaponised"},"has_fix":true,"headline":"Code Injection in SEOmatic","id":"CVE-2021-41749","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Cross-site Scripting in SEOmatic plugin","id":"CVE-2021-41750"},"packages":[{"ecosystem":"Packagist","fixed":["3.4.11"],"introduced":["0"],"last_affected":[],"package":"nystudio107/craft-seomatic","purl":null,"source":"GHSA-g7xr-v82w-qggq"},{"ecosystem":"Packagist","fixed":["3.4.11"],"introduced":["0"],"last_affected":[],"package":"nystudio107/craft-seomatic","purl":"pkg:composer/nystudio107/craft-seomatic","source":"GHSA-g7xr-v82w-qggq"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-41747"},"products":["n/a"],"published":"2022-06-12","related":[{"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"},{"cvss_score":6.1,"headline":"Cross-site Scripting in SEOmatic plugin","id":"CVE-2021-41750","kev_date_added":null,"published":"2022-06-12"}],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Unauthenticated attackers can achieve remote code execution via Server-Side Template Injection in the SEOmatic plugin for Craft CMS.","url":"https://insights.sbomify.com/CVE-2021-41749/"}
