Published Jul 25, 2022 · Updated Aug 3, 2024

Stored HTML injection in OpenTeknik Open Source Social Network 6.3 LTS allows remote authenticated users to alter post displays. The wall-post action accepts HTML in the location field and persists it without neutralization, causing the markup to render whenever the post page is viewed. An attacker must sign in or register an account and submit a crafted location value; the demonstration establishes persistent content modification and browser-side script execution.
