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-2026-126129/ (Markdown: https://insights.sbomify.com/CVE-2026-126129/index.md)","id":"CVE-2026-126129","markdown":"https://insights.sbomify.com/CVE-2026-126129/index.md","name":"CVE-2026-126129","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":"Okta","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[{"id":"CWE-807","name":"Reliance on Untrusted Inputs in a Security Decision"},{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-1254","name":"Incorrect Comparison Logic Granularity"}],"description":"The Auth0 ASP.NET Core Authentication SDK incorrectly determines a session's OIDC Back-Channel Logout status, which may result in a logged-out session being accepted for access to protected endpoints.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"The Auth0 ASP.NET Core Authentication SDK incorrectly determines a session's OIDC Back-Channel Logout status, which may result in a logged-o","id":"CVE-2026-126129","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Attachments could be replaced with local file content when forwarding","id":"CVE-2026-126132"},"nickname":null,"packages":[],"prev":{"headline":"The Management API client in the Auth0 Node.js SDK improperly neutralizes path parameters, allowing a request and its attached management AP","id":"CVE-2026-126128"},"products":["Auth0 ASP.NET Core Authentication"],"published":"2026-11-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-11-10","vendors":["Auth0"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-126129/"}
