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-2021-26067 in the wild and no public exploit code.\n\nAffected product: Atlassian Bamboo. 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-2021-26067/ (Markdown: https://insights.sbomify.com/CVE-2021-26067/index.md)","id":"CVE-2021-26067","markdown":"https://insights.sbomify.com/CVE-2021-26067/index.md","name":"CVE-2021-26067","record":{"aliases":["GHSA-wr59-chw8-frf6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Bamboo","requires_auth":"none","summary":"Unauthenticated attackers can view stack traces revealing home directory paths and file existence via the /chart endpoint.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"bamboo","vendor":"atlassian"}],"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":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Affected versions of Atlassian Bamboo allow an unauthenticated remote attacker to view a stack trace that may reveal the path for the home directory in disk and if certain files exists on the tmp directory, via a Sensitive Data Exposure vulnerability in the /chart endpoint.
