Combined with the absence of CSRF protection on DownloadServlet, an unauthenticated attacker can trick a logged-in administrator into triggering the token leak, then replay the stolen token to gain full administrative access to the Payara domain, leading to arbitrary code execution via WAR deployment. The vulnerability exists in the DownloadServlet and associated ContentSource implementations (LogViewerContentSource, LogFilesContentSource, LBConfigContentSource, ClientStubsContentSource) within the admingui:console-common module.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/S:P/AU:Y/R:U/V:C/RE:M/U:Amber","score":7.3},"cvss_v3":null,"cwes":["CWE-352","CWE-918"],"references":["https://docs.payara.fish/community/docs/Release%20Notes/Release%20Notes%207.2026.6.html"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-12986","score":0.00274,"percentile":0.19634,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-x939-7fq5-v9v6","url":"https://osv.dev/vulnerability/GHSA-x939-7fq5-v9v6","summary":"Payara Server Full has a Cross-Site Request Forgery vulnerability","modified":"2026-09-25T20:15:03.918567718Z","packages":[{"ecosystem":"Maven","name":"fish.payara.distributions:payara","purl":"pkg:maven/fish.payara.distributions/payara","ranges":[">=4.0.0 <7.2026.6"],"fixed":["7.2026.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
