description

Pixelite Events Manager is affected by a reflected cross-site scripting issue; the available CNA information indicates releases through 7.4.2 may be affected. An unauthenticated attacker may cause script to run in a victim's browser when attacker-influenced input is rendered. The evidence does not specify further preconditions.

mitigation

Apply vendor-provided remediation or an updated release when available. Until then, restrict public access to the affected component where feasible and monitor or filter untrusted request input.
