description
Gridbox for Joomla versions before 2.20.5.0 are affected by a stored cross-site scripting flaw in review content. An attacker able to submit crafted review data may cause script to run when that stored content is viewed.
mitigation

outcome
Contextual check: a technique exists and was validated, but no deterministic check could cover this one.
