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-2025-46736 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Umbraco.Cms (NuGet): affected all versions; fixed in 10.8.10\n- Umbraco.Cms (NuGet): affected all versions; fixed in 10.8.10\n- Umbraco.Cms (NuGet): affected from 11.0.0-rc1; fixed in 13.8.1\n- Umbraco.Cms (NuGet): affected from 11.0.0-rc1; fixed in 13.8.1\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-2025-46736/ (Markdown: https://insights.sbomify.com/CVE-2025-46736/index.md)","id":"CVE-2025-46736","markdown":"https://insights.sbomify.com/CVE-2025-46736/index.md","name":"CVE-2025-46736","record":{"aliases":["GHSA-4g8m-5mj5-c8xg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Umbraco CMS","requires_auth":"none","summary":"Attackers can enumerate valid user accounts by analyzing login response timing, exposing user existence information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"umbraco_cms","vendor":"umbraco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","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-204","name":"Observable Response Discrepancy"}],"description":"Umbraco is a free and open source .NET content management system.
