Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-12452 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/traefik/traefik (Go): affected from 1.7.0; fixed in 1.7.12\n- github.com/traefik/traefik (Go): affected from 1.7.0; fixed in 1.7.12\n- github.com/traefik/traefik (Go): affected from 1.7.0; fixed in 1.7.12\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-2019-12452/ (Markdown: https://insights.sbomify.com/CVE-2019-12452/index.md)","id":"CVE-2019-12452","markdown":"https://insights.sbomify.com/CVE-2019-12452/index.md","name":"CVE-2019-12452","record":{"aliases":["GHSA-r3fq-cmmw-cpmm","GO-2023-1919"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Traefik reverse proxy","requires_auth":"low_privilege","summary":"Authenticated users can expose password hashes and keys via the API if it is publicly accessible without proper access control.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"traefik","vendor":"traefik"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"types/types.go in Containous Traefik 1.7.x through 1.7.11, when the --api flag is used and the API is publicly reachable and exposed without sufficient access control (which is contrary to the API documentation), allows remote authenticated users to discover password hashes by reading the Basic HTTP Authentication or Digest HTTP Authentication section, or discover a key by reading the ClientTLS section.
