An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-21695 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-2022-21695/ (Markdown: https://insights.sbomify.com/CVE-2022-21695/index.md)","id":"CVE-2022-21695","markdown":"https://insights.sbomify.com/CVE-2022-21695/index.md","name":"CVE-2022-21695","record":{"aliases":["DEBIAN-CVE-2022-21695","GHSA-99p8-9p2c-49j4","PYSEC-2022-46"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OnionShare file sharing","requires_auth":"none","summary":"Authenticated or public users can send hidden chat messages in OnionShare, bypassing participant visibility controls.","user_interaction":"required","vuln_class":"missing_authorization"},"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:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"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.
