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-2020-6794 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-6794/ (Markdown: https://insights.sbomify.com/CVE-2020-6794/index.md)","id":"CVE-2020-6794","markdown":"https://insights.sbomify.com/CVE-2020-6794/index.md","name":"CVE-2020-6794","record":{"aliases":["DEBIAN-CVE-2020-6794","GHSA-2v3r-qqr5-3x33","UBUNTU-CVE-2020-6794"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Thunderbird email client","requires_auth":"none","summary":"Attackers can access unencrypted stored passwords if a master password was set after upgrading from pre-60 versions, exposing sensitive credentials.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mozilla","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"thunderbird","vendor":"mozilla"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-459","name":"Incomplete Cleanup"},{"id":"CWE-312","name":"Cleartext Storage of Sensitive Information"}],"description":"If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible.
