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-2021-41867 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-2021-41867/ (Markdown: https://insights.sbomify.com/CVE-2021-41867/index.md)","id":"CVE-2021-41867","markdown":"https://insights.sbomify.com/CVE-2021-41867/index.md","name":"CVE-2021-41867","record":{"aliases":["DEBIAN-CVE-2021-41867","GHSA-6rvj-pw9w-jcvc","PYSEC-2026-696","UBUNTU-CVE-2021-41867"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OnionShare file sharing","requires_auth":"none","summary":"Remote attackers can retrieve the full list of participants in a non-public OnionShare chat session, exposing user identities.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"onionshare","vendor":"onionshare"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[],"description":"An information disclosure vulnerability in OnionShare 2.3 before 2.4 allows remote unauthenticated attackers to retrieve the full list of participants of a non-public OnionShare node via the --chat feature.","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":"Information disclosure vulnerability in OnionShare","id":"CVE-2021-41867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":3,"n_references":2,"next":{"headline":"Remote unauthenticated attackers able to upload files in Onionshare","id":"CVE-2021-41868"},"packages":[{"ecosystem":"PyPI","fixed":["2.4"],"introduced":["2.3"],"last_affected":[],"package":"onionshare-cli","purl":null,"source":"GHSA-6rvj-pw9w-jcvc"},{"ecosystem":"PyPI","fixed":["2.4"],"introduced":["2.3"],"last_affected":[],"package":"onionshare-cli","purl":"pkg:pypi/onionshare-cli","source":"GHSA-6rvj-pw9w-jcvc"},{"ecosystem":"PyPI","fixed":["2.4"],"introduced":["2.3"],"last_affected":[],"package":"onionshare-cli","purl":"pkg:pypi/onionshare-cli","source":"PYSEC-2026-696"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-41866"},"products":["n/a"],"published":"2021-10-04","related":[{"cvss_score":9.8,"headline":"Remote unauthenticated attackers able to upload files in Onionshare","id":"CVE-2021-41868","kev_date_added":null,"published":"2021-10-04"},{"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 retrieve the full list of participants in a non-public OnionShare chat session, exposing user identities.","url":"https://insights.sbomify.com/CVE-2021-41867/"}
