An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-31864 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- redmine (Bitnami): affected all versions; fixed in 4.0.9, 4.1.3, 4.2.1\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-2021-31864/ (Markdown: https://insights.sbomify.com/CVE-2021-31864/index.md)","id":"CVE-2021-31864","markdown":"https://insights.sbomify.com/CVE-2021-31864/index.md","name":"CVE-2021-31864","record":{"aliases":["BIT-redmine-2021-31864","DEBIAN-CVE-2021-31864","GHSA-jx78-fjmh-q5cc","UBUNTU-CVE-2021-31864"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Redmine project management","requires_auth":"none","summary":"Attackers can bypass add_issue_notes permissions via the incoming mail handler, allowing unauthorized note additions in Redmine.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"redmine","vendor":"redmine"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"Redmine before 4.0.9, 4.1.x before 4.1.3, and 4.2.x before 4.2.1 allows attackers to bypass the add_issue_notes permission requirement by leveraging the incoming mail handler.","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":"Missing authorization in n/a","id":"CVE-2021-31864","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"debian:debian_linux","products":["debian:debian_linux","redmine:redmine"],"type":"missing_authorization","year":"2021"},"n_packages":1,"n_references":3,"next":{"headline":"File upload in n/a","id":"CVE-2021-31865"},"packages":[{"ecosystem":"Bitnami","fixed":["4.0.9","4.1.3","4.2.1"],"introduced":["0","4.1.0","4.2.0"],"last_affected":[],"package":"redmine","purl":"pkg:bitnami/redmine","source":"BIT-redmine-2021-31864"}],"prev":{"headline":"Path traversal in n/a","id":"CVE-2021-31863"},"products":["n/a"],"published":"2021-04-28","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can bypass add_issue_notes permissions via the incoming mail handler, allowing unauthorized note additions in Redmine.","url":"https://insights.sbomify.com/CVE-2021-31864/"}
