It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50267 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Steeltoe.Configuration.Abstractions (NuGet): affected from 4.0.0; fixed in 4.2.0\n- Steeltoe.Configuration.Abstractions (NuGet): affected from 4.0.0; fixed in 4.2.0\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-2026-50267/ (Markdown: https://insights.sbomify.com/CVE-2026-50267/index.md)","id":"CVE-2026-50267","markdown":"https://insights.sbomify.com/CVE-2026-50267/index.md","name":"CVE-2026-50267","record":{"aliases":["GHSA-rxrh-4j9h-xgg9"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Steeltoe configuration library","requires_auth":"low_privilege","summary":"An attacker with local access can read TLS private keys from world-readable temporary files created by Steeltoe libraries.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-312","name":"Cleartext Storage of Sensitive Information"}],"description":"Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Configuration.Abstractions 4.0.0 through 4.1.0, when MySQL or PostgreSQL service bindings from `VCAP_SERVICES` include TLS client credentials, the Connectors library writes those credentials to temporary files in `Path.GetTempPath()` using `File.CreateText`. On Linux, `File.CreateText` creates files with mode `0644` (world-readable) under the process umask, and the files are never deleted. The same key material is protected at mode `0400` in `/proc/\u003cpid\u003e/environ`. Steeltoe.Configuration.Abstractions version 4.2.0 patches the issue. If an immediate upgrade is not possible, prevent other processes from running in the container under a different UID with access to `/tmp`.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Steeltoe: TLS private keys written to /tmp with default permissions, never deleted","id":"CVE-2026-50267","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Steeltoe: OAEP setting silently selects PKCS#1 v1.5 padding","id":"CVE-2026-50268"},"packages":[{"ecosystem":"NuGet","fixed":["4.2.0"],"introduced":["4.0.0"],"last_affected":[],"package":"Steeltoe.Configuration.Abstractions","purl":null,"source":"GHSA-rxrh-4j9h-xgg9"},{"ecosystem":"NuGet","fixed":["4.2.0"],"introduced":["4.0.0"],"last_affected":[],"package":"Steeltoe.Configuration.Abstractions","purl":"pkg:nuget/Steeltoe.Configuration.Abstractions","source":"GHSA-rxrh-4j9h-xgg9"}],"prev":{"headline":"OpenStack Neutron: Neutron port RBAC policy bypass allows project managers to set trusted device owners on shared networks","id":"CVE-2026-50266"},"products":["Steeltoe.Configuration.Abstractions"],"published":"2026-06-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-18","vendors":["SteeltoeOSS"]},"summary":"An attacker with local access can read TLS private keys from world-readable temporary files created by Steeltoe libraries.","url":"https://insights.sbomify.com/CVE-2026-50267/"}
