Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-46386 in the wild and no public exploit code.\n\nAffected product: opf openproject. 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-2026-46386/ (Markdown: https://insights.sbomify.com/CVE-2026-46386/index.md)","id":"CVE-2026-46386","markdown":"https://insights.sbomify.com/CVE-2026-46386/index.md","name":"CVE-2026-46386","record":{"aliases":["GHSA-r85r-gjq2-f83r"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenProject web app","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution in OpenProject Docker deployments due to hardcoded default secrets and unsafe cookie deserialization.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"},{"id":"CWE-1392","name":"Use of Default Credentials"},{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"OpenProject is open-source, web-based project management software.
