CVE-2026-105090 - Formbricks Stored Cross-Site Scripting Vulnerability
CVE ID :CVE-2026-105090
Published : Oct. 3, 2026, 2:17 a.m. | 2 hours, 56 minutes ago
Description :Formbricks before 5.4.4 and 6 before 6.0.1 allows stored XSS. The survey-level Custom Head Scripts feature did not enforce the documented Manage permission boundary. A workspace member holding only readWrite permission could configure Custom Head Scripts on a survey, an operation the documentation restricts to the Manage role. Because the configured scripts execute in the authenticated browser session of any user who opens the affected survey, a lower-privileged member can run arbitrary JavaScript (stored cross-site scripting) in the session of higher-privileged users. Fixed versions require Manage access to modify survey Custom Head Scripts.
Severity: 5.1 | MEDIUM
