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-2022-21689 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- onionshare-cli (PyPI): affected all versions; fixed in 2.5\n- onionshare-cli (PyPI): affected all versions; fixed in 2.5\n- onionshare-cli (PyPI): affected all versions; fixed in 2.5\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-2022-21689/ (Markdown: https://insights.sbomify.com/CVE-2022-21689/index.md)","id":"CVE-2022-21689","markdown":"https://insights.sbomify.com/CVE-2022-21689/index.md","name":"CVE-2022-21689","record":{"aliases":["DEBIAN-CVE-2022-21689","GHSA-jh82-c5jw-pxpc","PYSEC-2022-40","UBUNTU-CVE-2022-21689"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OnionShare file sharing","requires_auth":"none","summary":"An attacker can block file uploads for other users in OnionShare receive mode by triggering a rate limit, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"onionshare","vendor":"onionshare"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"OnionShare is an open source tool that lets you securely and anonymously share files, host websites, and chat with friends using the Tor network.

An adversary with access to the receive mode can block file upload for others.
