Stored script execution via unsanitized classification names
Published Apr 7, 2025 · Updated Apr 8, 2025
Stored cross-site scripting in LinZhaoguan pb-cms 2.0 allows remote authenticated users to execute scripts through classification names. The back-end Classification Management function stores a script payload supplied as a classification name and later renders it in the article list without neutralization. High-privileged access is required to save the payload, and another user must open the affected article list; the script then runs in that user's browser context.
