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-2025-3871 in the wild and no public exploit code.\n\nAffected product: Fortra GoAnywhere MFT. 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-2025-3871/ (Markdown: https://insights.sbomify.com/CVE-2025-3871/index.md)","id":"CVE-2025-3871","markdown":"https://insights.sbomify.com/CVE-2025-3871/index.md","name":"CVE-2025-3871","record":{"aliases":["GHSA-p75j-78r4-rcp2"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Managed File Transfer","requires_auth":"none","summary":"An attacker can disable users by exploiting broken access control in GoAnywhere MFT when GOTP 2FA is enabled and email is missing.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fortra","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Broken access control in Fortra's GoAnywhere MFT prior to 7.8.1 allows an attacker to create a denial of service situation when configured to use GoAnywhere One-Time Password (GOTP) email two-factor authentication (2FA) and the user has not set an email address.
