Attackers can submit a crafted email parameter containing ERB expressions through the admin settings test_email endpoint, causing the Rails inline template renderer to evaluate attacker-controlled Ruby code and achieve arbitrary command execution as the Rails process user.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","score":6.6},"cwes":["CWE-1336"],"references":["https://enrik-m.github.io/posts/Camaleon-CMS-Vulnerabilties/#44-stored-xss-via-draft-post-title","https://github.com/owen2345/camaleon-cms","https://www.vulncheck.com/advisories/camaleoncms-server-side-template-injection-via-test-email-action"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-73330","score":0.00789,"percentile":0.55973,"date":"2026-10-25"},"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).
