Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-21696 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 from 2.3; fixed in 2.5\n- onionshare-cli (PyPI): affected from 2.3; 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-2022-21696/ (Markdown: https://insights.sbomify.com/CVE-2022-21696/index.md)","id":"CVE-2022-21696","markdown":"https://insights.sbomify.com/CVE-2022-21696/index.md","name":"CVE-2022-21696","record":{"aliases":["DEBIAN-CVE-2022-21696","GHSA-68vr-8f46-vc9f","PYSEC-2022-47"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OnionShare chat tool","requires_auth":"low_privilege","summary":"Attackers can impersonate other chat participants in OnionShare by appending whitespace to usernames, bypassing identity verification.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"onionshare","vendor":"onionshare"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"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.
