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-2021-41868 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- onionshare-cli (PyPI): affected from 2.3; fixed in 2.4\n- onionshare-cli (PyPI): affected from 2.3; fixed in 2.4\n- onionshare-cli (PyPI): affected from 2.3; fixed in 2.4\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-2021-41868/ (Markdown: https://insights.sbomify.com/CVE-2021-41868/index.md)","id":"CVE-2021-41868","markdown":"https://insights.sbomify.com/CVE-2021-41868/index.md","name":"CVE-2021-41868","record":{"aliases":["DEBIAN-CVE-2021-41868","GHSA-7g47-xxff-9p85","PYSEC-2026-434","UBUNTU-CVE-2021-41868"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"OnionShare file sharing","requires_auth":"none","summary":"Remote attackers can upload files to OnionShare receive nodes, potentially storing malicious content on the host system.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"onionshare","vendor":"onionshare"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"OnionShare 2.3 before 2.4 allows remote unauthenticated attackers to upload files on a non-public node when using the --receive functionality.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Remote unauthenticated attackers able to upload files in Onionshare","id":"CVE-2021-41868","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":3,"n_references":2,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2021-41869"},"packages":[{"ecosystem":"PyPI","fixed":["2.4"],"introduced":["2.3"],"last_affected":[],"package":"onionshare-cli","purl":null,"source":"GHSA-7g47-xxff-9p85"},{"ecosystem":"PyPI","fixed":["2.4"],"introduced":["2.3"],"last_affected":[],"package":"onionshare-cli","purl":"pkg:pypi/onionshare-cli","source":"GHSA-7g47-xxff-9p85"},{"ecosystem":"PyPI","fixed":["2.4"],"introduced":["2.3"],"last_affected":[],"package":"onionshare-cli","purl":"pkg:pypi/onionshare-cli","source":"PYSEC-2026-434"}],"prev":{"headline":"Information disclosure vulnerability in OnionShare","id":"CVE-2021-41867"},"products":["n/a"],"published":"2021-10-04","related":[{"cvss_score":8.7,"headline":"Cross-Site Scripting in Onionshare","id":"CVE-2022-21690","kev_date_added":null,"published":"2022-01-18"},{"cvss_score":7.5,"headline":"Out-of-bounds Read in Onionshare","id":"CVE-2022-21688","kev_date_added":null,"published":"2022-01-18"},{"cvss_score":7.5,"headline":"Denial of Service in Onionshare","id":"CVE-2022-21689","kev_date_added":null,"published":"2022-01-18"},{"cvss_score":7,"headline":"Path traversal in n/a","id":"CVE-2018-19960","kev_date_added":null,"published":"2018-12-07"},{"cvss_score":6.3,"headline":"Path traversal in Onionshare","id":"CVE-2022-21693","kev_date_added":null,"published":"2022-01-18"},{"cvss_score":5.5,"headline":"Race condition in n/a","id":"CVE-2016-5026","kev_date_added":null,"published":"2017-01-30"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can upload files to OnionShare receive nodes, potentially storing malicious content on the host system.","url":"https://insights.sbomify.com/CVE-2021-41868/"}
