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-2025-59934 exists.\n\nAffected product: formbricks. 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-2025-59934/ (Markdown: https://insights.sbomify.com/CVE-2025-59934/index.md)","id":"CVE-2025-59934","markdown":"https://insights.sbomify.com/CVE-2025-59934/index.md","name":"CVE-2025-59934","record":{"aliases":["GHSA-7229-q9pv-j6p4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Formbricks survey platform","requires_auth":"none","summary":"Attackers can bypass authentication and reset passwords by crafting unsigned JWTs due to missing signature verification in Formbricks.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"Formbricks is an open source qualtrics alternative. Prior to version 4.0.1, Formbricks is missing JWT signature verification. This vulnerability stems from a token validation routine that only decodes JWTs (jwt.decode) without verifying their signatures. Both the email verification token login path and the password reset server action use the same validator, which does not check the token’s signature, expiration, issuer, or audience. If an attacker learns the victim’s actual user.id, they can craft an arbitrary JWT with an alg: \"none\" header and use it to authenticate and reset the victim’s password. This issue has been patched in version 4.0.1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-10-07","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-10-07T03:47:35Z","kind":"github_poc","ref":"https://github.com/suriryuk/cve-2025-59934","stars":0,"title":"cve-2025-59934 PoC"}],"tier":"weaponised"},"has_fix":false,"headline":"Formbricks missing JWT signature verification","id":"CVE-2025-59934","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"GLPI Vulnerable to Unauthenticated Stored XSS on the Inventory page","id":"CVE-2025-59935"},"packages":[],"prev":{"headline":"libvips is vulnerable to Buffer Over-Read in poppler-based pdfload","id":"CVE-2025-59933"},"products":["formbricks"],"published":"2025-09-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-09-29","vendors":["formbricks"]},"summary":"Attackers can bypass authentication and reset passwords by crafting unsigned JWTs due to missing signature verification in Formbricks.","url":"https://insights.sbomify.com/CVE-2025-59934/"}
