CVE-2025-31983Network attack vector

Authenticated script injection via misconfigured CSP header

Published May 6, 2026 · Updated May 6, 2026

Cross-site scripting in HCL BigFix Service Management 23 allows remote authenticated users to inject scripts through a faulty CSP header. The public advisory identifies the Content Security Policy header as the faulty locus but does not disclose the affected directive, endpoint, or injection path. Low-privileged access and user interaction are required; successful exploitation permits sensitive-information exposure and limited service interruption.
