CVE-2023-1726Network attack vector

Authenticated stored cross-site scripting

Published Apr 7, 2023 · Updated May 22, 2026

Cross-site scripting in Proliz Software OBS before 23.04.01 allows remote authenticated users to store scripts for later browser execution. The published record identifies improper neutralization during web-page generation but does not disclose the affected field, endpoint, or rendering code. Low-privileged authentication and later user interaction are required; exploitation executes attacker-supplied script in that user's browser context.
