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-2020-18671 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- roundcube (Bitnami): affected all versions; fixed in 1.4.4\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-2020-18671/ (Markdown: https://insights.sbomify.com/CVE-2020-18671/index.md)","id":"CVE-2020-18671","markdown":"https://insights.sbomify.com/CVE-2020-18671/index.md","name":"CVE-2020-18671","record":{"aliases":["BIT-roundcube-2020-18671","DEBIAN-CVE-2020-18671","GHSA-rxrc-3842-v7v6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Roundcube Mail","requires_auth":"low_privilege","summary":"Cross-site scripting in Roundcube Mail installer allows attackers to execute scripts via SMTP configuration, potentially compromising user accounts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"webmail","vendor":"roundcube"}],"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":"Cross Site Scripting (XSS) vulnerability in Roundcube Mail \u003c=1.4.4 via smtp config in /installer/test.php.","ecosystems":["Bitnami"],"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 n/a","id":"CVE-2020-18671","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"roundcube:webmail","products":["roundcube:webmail"],"type":"xss","year":"2020"},"n_packages":1,"n_references":3,"next":{"headline":"Other in n/a","id":"CVE-2020-18683"},"packages":[{"ecosystem":"Bitnami","fixed":["1.4.4"],"introduced":["0"],"last_affected":[],"package":"roundcube","purl":"pkg:bitnami/roundcube","source":"BIT-roundcube-2020-18671"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-18670"},"products":["n/a"],"published":"2021-06-24","related":[{"cvss_score":9.3,"headline":"RoundCube Webmail Cross-Site Scripting","id":"CVE-2024-42009","kev_date_added":"2025-06-09","published":"2024-08-05"},{"cvss_score":7.2,"headline":"RoundCube Webmail Cross-site Scripting","id":"CVE-2025-68461","kev_date_added":"2026-02-20","published":"2025-12-18"},{"cvss_score":10,"headline":"PHPMailer susceptible to arbitrary code execution","id":"CVE-2008-5619","kev_date_added":null,"published":"2008-12-17"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2024-37385","kev_date_added":null,"published":"2024-06-07"},{"cvss_score":9.3,"headline":"Cross-site scripting in n/a","id":"CVE-2024-42008","kev_date_added":null,"published":"2024-08-05"},{"cvss_score":8.8,"headline":"Command injection in Webmail","id":"CVE-2026-74997","kev_date_added":null,"published":"2026-08-17"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-8114","kev_date_added":null,"published":"2017-04-29"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"Cross-site scripting in Roundcube Mail installer allows attackers to execute scripts via SMTP configuration, potentially compromising user accounts.","url":"https://insights.sbomify.com/CVE-2020-18671/"}
