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-2021-27912 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mautic/core (Packagist): affected all versions; fixed in 3.3.4\n- mautic/core (Packagist): affected all versions; fixed in 3.3.4\n- mautic/core (Packagist): affected from 4.0.0-alpha1; fixed in 4.0.0\n- mautic/core (Packagist): affected from 4.0.0-alpha1; fixed in 4.0.0\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-2021-27912/ (Markdown: https://insights.sbomify.com/CVE-2021-27912/index.md)","id":"CVE-2021-27912","markdown":"https://insights.sbomify.com/CVE-2021-27912/index.md","name":"CVE-2021-27912","record":{"aliases":["GHSA-rh5w-82wh-jhr8"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Mautic marketing automation","requires_auth":"low_privilege","summary":"Authenticated users with asset permissions can execute arbitrary JavaScript via inline JS in asset titles, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mautic","cpe":[{"product":"mautic","vendor":"acquia"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Mautic versions before 3.3.4/4.0.0 are vulnerable to an inline JS XSS attack when viewing Mautic assets by utilizing inline JS in the title and adding a broken image URL as a remote asset.
