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-2026-47840 in the wild and no public exploit code.\n\nAffected product: CloudFoundry Foundation Cf-deployment. 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-2026-47840/ (Markdown: https://insights.sbomify.com/CVE-2026-47840/index.md)","id":"CVE-2026-47840","markdown":"https://insights.sbomify.com/CVE-2026-47840/index.md","name":"CVE-2026-47840","record":{"aliases":["GHSA-rh75-5vxf-83m5"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"CloudFoundry UAA","requires_auth":"none","summary":"A network attacker can bypass TLS hostname verification in LDAP StartTLS to steal credentials and forge admin group memberships in CloudFoundry UAA deployments.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[],"description":"A network attacker positioned between UAA and its LDAP directory can impersonate the directory using any certificate from any trusted CA, then harvest the LDAP bind password and every end-user password sent during simple-bind authentication, and return forged group memberships that grant themselves admin scopes.
