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-2021-3138 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- discourse (Bitnami): affected all versions up to 2.6.0; no fix listed\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-2021-3138/ (Markdown: https://insights.sbomify.com/CVE-2021-3138/index.md)","id":"CVE-2021-3138","markdown":"https://insights.sbomify.com/CVE-2021-3138/index.md","name":"CVE-2021-3138","record":{"aliases":["BIT-discourse-2021-3138","GHSA-w9c3-h2rq-jrff"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Discourse forum","requires_auth":"none","summary":"Attackers can bypass rate limits to circumvent two-factor authentication requirements on specific forms in Discourse.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"discourse","vendor":"discourse"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"In Discourse 2.7.0 through beta1, a rate-limit bypass leads to a bypass of the 2FA requirement for certain forms.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2021-01-12","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-01-12T22:50:27Z","kind":"github_poc","ref":"https://github.com/Mesh3l911/CVE-2021-3138","stars":1,"title":"Discource POC"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Security feature bypass in n/a","id":"CVE-2021-3138","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"discourse:discourse","products":["discourse:discourse"],"type":"security_feature_bypass","year":"2021"},"n_packages":1,"n_references":3,"next":{"headline":"Path traversal in n/a","id":"CVE-2021-3139"},"packages":[{"ecosystem":"Bitnami","fixed":[],"introduced":["0"],"last_affected":["2.6.0"],"package":"discourse","purl":"pkg:bitnami/discourse","source":"BIT-discourse-2021-3138"}],"prev":{"headline":"Cross Site Scripting (XSS) in XWiki","id":"CVE-2021-3137"},"products":["n/a"],"published":"2021-01-14","related":[{"cvss_score":10,"headline":"RCE via malicious SNS subscription payload","id":"CVE-2021-41163","kev_date_added":null,"published":"2021-10-20"},{"cvss_score":9.1,"headline":"Discourse vulnerable to RCE via admins uploading maliciously zipped file","id":"CVE-2022-36066","kev_date_added":null,"published":"2022-09-29"},{"cvss_score":8.9,"headline":"Discourse user account takeover via email and invite link","id":"CVE-2022-39356","kev_date_added":null,"published":"2022-11-02"},{"cvss_score":8.8,"headline":"Discourse vulnerable to Cross-site Scripting in local oneboxes","id":"CVE-2023-22468","kev_date_added":null,"published":"2023-01-26"},{"cvss_score":8.7,"headline":"Discourse leaks private topic title and post excerpt via user action API endpoint","id":"CVE-2026-27934","kev_date_added":null,"published":"2026-03-19"},{"cvss_score":8.7,"headline":"Discourse vulnerable to DoS via large URL payload in PM to a bot","id":"CVE-2025-48053","kev_date_added":null,"published":"2025-06-09"},{"cvss_score":8.6,"headline":"Discourse vulnerable to unlimited mentioned users in message serializer","id":"CVE-2023-48297","kev_date_added":null,"published":"2024-01-12"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can bypass rate limits to circumvent two-factor authentication requirements on specific forms in Discourse.","url":"https://insights.sbomify.com/CVE-2021-3138/"}
