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-2021-3901 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- grumpydictator/firefly-iii (Packagist): affected all versions up to 5.6.2; no fix listed\n- grumpydictator/firefly-iii (Packagist): affected all versions up to 5.6.2; 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-2021-3901/ (Markdown: https://insights.sbomify.com/CVE-2021-3901/index.md)","id":"CVE-2021-3901","markdown":"https://insights.sbomify.com/CVE-2021-3901/index.md","name":"CVE-2021-3901","record":{"aliases":["GHSA-rqgp-ccph-5w65"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Firefly III","requires_auth":"low_privilege","summary":"Attackers can trick authenticated users into performing unintended actions in Firefly III, potentially modifying financial data.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"firefly_iii","vendor":"firefly-iii"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"firefly-iii is vulnerable to Cross-Site Request Forgery (CSRF)","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Cross-Site Request Forgery (CSRF) in firefly-iii/firefly-iii","id":"CVE-2021-3901","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Improper Restriction of XML External Entity Reference in dompdf/dompdf","id":"CVE-2021-3902"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["5.6.2"],"package":"grumpydictator/firefly-iii","purl":null,"source":"GHSA-rqgp-ccph-5w65"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["5.6.2"],"package":"grumpydictator/firefly-iii","purl":"pkg:composer/grumpydictator/firefly-iii","source":"GHSA-rqgp-ccph-5w65"}],"prev":{"headline":"Cross-Site Request Forgery (CSRF) in firefly-iii/firefly-iii","id":"CVE-2021-3900"},"products":["firefly-iii/firefly-iii"],"published":"2021-10-27","related":[{"cvss_score":6.5,"headline":"Incorrect Authorization in firefly-iii/firefly-iii","id":"CVE-2023-0298","kev_date_added":null,"published":"2023-01-14"},{"cvss_score":6.5,"headline":"Cross-Site Request Forgery (CSRF) in firefly-iii/firefly-iii","id":"CVE-2021-3728","kev_date_added":null,"published":"2021-08-23"},{"cvss_score":6.5,"headline":"Cross-Site Request Forgery (CSRF) in firefly-iii/firefly-iii","id":"CVE-2021-3730","kev_date_added":null,"published":"2021-08-23"},{"cvss_score":6.3,"headline":"Unrestricted Upload of File with Dangerous Type in firefly-iii/firefly-iii","id":"CVE-2021-3846","kev_date_added":null,"published":"2021-10-19"},{"cvss_score":6.1,"headline":"Firefly III allows webhooks HTML Injection.","id":"CVE-2024-22075","kev_date_added":null,"published":"2024-01-05"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2019-14667","kev_date_added":null,"published":"2019-08-05"},{"cvss_score":5.4,"headline":"Insufficient Session Expiration in firefly-iii/firefly-iii","id":"CVE-2023-1788","kev_date_added":null,"published":"2023-04-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-08-03","vendors":["firefly-iii"]},"summary":"Attackers can trick authenticated users into performing unintended actions in Firefly III, potentially modifying financial data.","url":"https://insights.sbomify.com/CVE-2021-3901/"}
