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-2021-31778 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- amazing/media2click (Packagist): affected from 1.0.0; fixed in 1.3.3\n- amazing/media2click (Packagist): affected from 1.0.0; fixed in 1.3.3\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-2021-31778/ (Markdown: https://insights.sbomify.com/CVE-2021-31778/index.md)","id":"CVE-2021-31778","markdown":"https://insights.sbomify.com/CVE-2021-31778/index.md","name":"CVE-2021-31778","record":{"aliases":["GHSA-xpxm-pf7g-2534"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 extension","requires_auth":"low_privilege","summary":"A backend user can inject malicious scripts via the media2click extension, potentially leading to code execution in the TYPO3 CMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"media2click","vendor":"media2click_project"}],"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 media2click (aka 2 Clicks for External Media) extension 1.x before 1.3.3 for TYPO3 allows XSS by a backend user account.","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 media2click","id":"CVE-2021-31778","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Server-Side Request Forgery in yoast_seo","id":"CVE-2021-31779"},"packages":[{"ecosystem":"Packagist","fixed":["1.3.3"],"introduced":["1.0.0"],"last_affected":[],"package":"amazing/media2click","purl":null,"source":"GHSA-xpxm-pf7g-2534"},{"ecosystem":"Packagist","fixed":["1.3.3"],"introduced":["1.0.0"],"last_affected":[],"package":"amazing/media2click","purl":"pkg:composer/amazing/media2click","source":"GHSA-xpxm-pf7g-2534"}],"prev":{"headline":"SQL Injection in t3/dce","id":"CVE-2021-31777"},"products":["n/a"],"published":"2021-04-28","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":"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":["n/a"]},"summary":"A backend user can inject malicious scripts via the media2click extension, potentially leading to code execution in the TYPO3 CMS.","url":"https://insights.sbomify.com/CVE-2021-31778/"}
