Contributor-level stored cross-site scripting

Published Jun 17, 2025 · Updated Apr 28, 2026

Stored cross-site scripting in If-So Dynamic Content Personalization 1.9.3.1 and earlier allows remote authenticated users to inject scripts. Patchstack has not disclosed the affected input, code locus, or exact sanitization and escaping failure that stores the payload. Contributor-level access is required, and the script runs after another user visits the affected content, exposing that user's browser session to attacker-controlled actions.
