The markup field from stored portlet configuration is passed directly to custFactory.createResult() without a TemplateClassResolver restriction or FreeMarker sandboxing in BasicConfiguration, leaving built-ins such as ?new and freemarker.template.utility.Execute available, causing the payload to execute in the application server process context when any user renders a dashboard containing the affected portlet.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":8.0},"cwes":["CWE-1336"],"references":["https://blog.evan.lat/posts/openeq","https://github.com/openequella/openEQUELLA/commit/d6e165afc986f8a3ed912cdb367d5ad8c1eeab5c","https://github.com/openequella/openEQUELLA/releases/tag/2026.1.0","https://github.com/openequella/openEQUELLA/security/advisories/GHSA-62g6-mmp6-9wv2","https://www.vulncheck.com/advisories/openequella-authenticated-stored-ssti-via-freemarkerportletrenderer"],"products":[],"source":"nvd","synced_at":"2026-10-29T13:36:54.456004701+00:00"},"epss":{"cve":"CVE-2026-94109","score":0.00778,"percentile":0.55739,"date":"2026-10-28"},"kev":null,"osv":[],"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).
