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-2020-5426 in the wild and no public exploit code.\n\nAffected product: VMware Tanzu Pivotal Scheduler. 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-2020-5426/ (Markdown: https://insights.sbomify.com/CVE-2020-5426/index.md)","id":"CVE-2020-5426","markdown":"https://insights.sbomify.com/CVE-2020-5426/index.md","name":"CVE-2020-5426","record":{"aliases":["GHSA-3cvg-mw7q-93pw"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"VMware Tanzu Scheduler","requires_auth":"none","summary":"Scheduler for TAS may transmit privileged UAA tokens in plaintext over non-TLS connections, allowing attackers to intercept tokens and gain admin access.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"pivotal","cpe":[{"product":"pivotal_scheduler","vendor":"vmware"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"Scheduler for TAS prior to version 1.4.0 was permitting plaintext transmission of UAA client token by sending it over a non-TLS connection.
