An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-27909 exists.\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-2021-27909/ (Markdown: https://insights.sbomify.com/CVE-2021-27909/index.md)","id":"CVE-2021-27909","markdown":"https://insights.sbomify.com/CVE-2021-27909/index.md","name":"CVE-2021-27909","record":{"aliases":["GHSA-32hw-3pvh-vcvc"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mautic marketing automation","requires_auth":"none","summary":"An attacker can execute JavaScript on the password reset page via a vulnerable URL parameter, requiring user interaction to trigger.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mautic","cpe":[{"product":"mautic","vendor":"acquia"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"For Mautic versions prior to 3.3.4/4.0.0, there is an XSS vulnerability on Mautic's password reset page where a vulnerable parameter, \"bundle,\" in the URL could allow an attacker to execute Javascript code.
