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-2026-88819 in the wild and no public exploit code.\n\nAffected product: Eclipse Data Plane Core. 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-2026-88819/ (Markdown: https://insights.sbomify.com/CVE-2026-88819/index.md)","id":"CVE-2026-88819","markdown":"https://insights.sbomify.com/CVE-2026-88819/index.md","name":"CVE-2026-88819","record":{"aliases":["GHSA-2f3m-r9cf-82r7"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Eclipse Data Plane Core","requires_auth":"none","summary":"Attackers can bypass authentication in Eclipse Data Plane Core because the refresh token handler fails to verify proof of possession of the issuer DID.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"In Siglet current and past versions the refresh token handler do not enforce proof of possession of the issuer DID.","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":"Auth bypass in Eclipse Data Plane Core","id":"CVE-2026-88819","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Master Blocks 1.4.1 - 1.4.1.4 - Unauthenticated Stored XSS via White Label Settings","id":"CVE-2026-88824"},"packages":[],"prev":{"headline":"Privilege escalation via legacy access group creation endpoint","id":"CVE-2026-88817"},"products":["Eclipse Data Plane Core"],"published":"2026-09-14","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)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["Eclipse Foundation"]},"summary":"Attackers can bypass authentication in Eclipse Data Plane Core because the refresh token handler fails to verify proof of possession of the issuer DID.","url":"https://insights.sbomify.com/CVE-2026-88819/"}
