An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-43781 exists.\n\nAffected product: Atlassian Bitbucket Data Center. 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-2022-43781/ (Markdown: https://insights.sbomify.com/CVE-2022-43781/index.md)","id":"CVE-2022-43781","markdown":"https://insights.sbomify.com/CVE-2022-43781/index.md","name":"CVE-2022-43781","record":{"aliases":["GHSA-3883-h64p-r3xm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Bitbucket Server","requires_auth":"none","summary":"Attackers can execute arbitrary code via command injection in environment variables, potentially unauthenticated if public signup is enabled.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"bitbucket","vendor":"atlassian"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"There is a command injection vulnerability using environment variables in Bitbucket Server and Data Center.
