An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-8590 in the wild and no public exploit code.\n\nAffected product: Spotfire Enterprise. 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-2026-8590/ (Markdown: https://insights.sbomify.com/CVE-2026-8590/index.md)","id":"CVE-2026-8590","markdown":"https://insights.sbomify.com/CVE-2026-8590/index.md","name":"CVE-2026-8590","record":{"aliases":["GHSA-q55h-7282-gq6q"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Spotfire Enterprise","requires_auth":"none","summary":"Attackers can bypass OAuth2 PKCE security controls for public clients in Spotfire Enterprise server modules.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Spotfire","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[],"description":"Vulnerability in Spotfire Spotfire Enterprise (Spotfire Server modules), Spotfire Spotfire Enterprise with External Consumers (Spotfire Server modules), Spotfire Spotfire on Kubernetes (Spotfire Server modules).\n\nThis issue affects Spotfire Enterprise: through 14.0.12, through 14.4.2, through 14.5.0, through 14.6.1, through 14.6.2, through 14.7.0, through 14.8.0; Spotfire Enterprise with External Consumers: through 14.0.12, through 14.5.0, through 14.6.0, through 14.6.1, through 14.6.2, through 14.7.0, through 14.8.0; Spotfire on Kubernetes: through 4.2.0, 5.0.X, 6.0.X.","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":"Spotfire OAuth2 PKCE Bypass for public clients","id":"CVE-2026-8590","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":"OS Command Injection in Rapid7 InsightConnect AWK Plugin","id":"CVE-2026-8592"},"packages":[],"prev":{"headline":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in GitLab","id":"CVE-2026-8589"},"products":["Spotfire Enterprise","Spotfire Enterprise with External Consumers","Spotfire on Kubernetes"],"published":"2026-07-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-14","vendors":["Spotfire"]},"summary":"Attackers can bypass OAuth2 PKCE security controls for public clients in Spotfire Enterprise server modules.","url":"https://insights.sbomify.com/CVE-2026-8590/"}
