An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-33667 exists.\n\nAffected product: opf openproject. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-33667/ (Markdown: https://insights.sbomify.com/CVE-2026-33667/index.md)","id":"CVE-2026-33667","markdown":"https://insights.sbomify.com/CVE-2026-33667/index.md","name":"CVE-2026-33667","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Project management application","requires_auth":"none","summary":"Attackers can bypass two-factor authentication by brute-forcing OTP codes due to missing rate limiting, leading to account takeover.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"openproject","vendor":"openproject"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"OpenProject is an open-source project management application. In versions prior to 17.3.0, 2FA OTP verification in the confirm_otp action of the two_factor_authentication module has no rate limiting, lockout mechanism, or failed-attempt tracking. The existing brute_force_block_after_failed_logins setting only counts password login failures and does not apply to the 2FA verification stage, and neither the fail_login nor stage_failure methods increment any counter, lock the account, or add any delay. With the default TOTP drift window of ±60 seconds allowing approximately 5 valid codes at any time, an attacker who knows a user's password can brute-force the 6-digit TOTP code at roughly 5-10 attempts per second with an expected completion time of approximately 11 hours. The same vulnerability applies to backup code verification. This effectively allows complete 2FA bypass for any account where the password is known. This issue has been fixed in version 17.3.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"OpenProject: 2FA OTP Verification Missing Rate Limiting","id":"CVE-2026-33667","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Vikunja Allows Disabled/Locked User Accounts to Authenticate via API Tokens, CalDAV, and OpenID Connect","id":"CVE-2026-33668"},"packages":[],"prev":{"headline":"Zserio: Integer Overflow in BitStreamReader on 32-bit platforms","id":"CVE-2026-33666"},"products":["openproject"],"published":"2026-04-15","related":[{"cvss_score":9.9,"headline":"OpenProject: SQL Injection in Cost Reporting =n Operator via parse_number_string","id":"CVE-2026-34717","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":9.4,"headline":"Command Injection on OpenProject repositories leads to Remote Code Execution","id":"CVE-2026-25763","kev_date_added":null,"published":"2026-02-06"},{"cvss_score":9.4,"headline":"OpenProject has Argument Injection on Repository module that allows Arbitrary File Write","id":"CVE-2026-24685","kev_date_added":null,"published":"2026-01-28"},{"cvss_score":9.1,"headline":"OpenProject has a SQL Injection via Custom Field Name that can be chained to Remote Code Execution","id":"CVE-2026-32698","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":9.1,"headline":"OpenProject's repository files are served with the MIME type allowing them to be used to bypass Content Security Policy","id":"CVE-2026-32703","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":9.1,"headline":"OpenProject is Vulnerable to Arbitrary File Read via ImageMagick SVG Coder","id":"CVE-2026-22600","kev_date_added":null,"published":"2026-01-10"},{"cvss_score":8.9,"headline":"OpenProject has SSRF and CSWSH in Hocuspocus Synchronization Server","id":"CVE-2026-24772","kev_date_added":null,"published":"2026-01-28"}],"sources":[{"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-15","vendors":["opf"]},"summary":"Attackers can bypass two-factor authentication by brute-forcing OTP codes due to missing rate limiting, leading to account takeover.","url":"https://insights.sbomify.com/CVE-2026-33667/"}
