CVE-2025-48828: vBulletin

High severity, CVSS 8.1. EPSS: 57.6% chance of exploitation in the next 30 days.

Certain vBulletin versions might allow attackers to execute arbitrary PHP code by abusing Template Conditionals in the template engine. By crafting template code in an alternative PHP function invocation syntax, such as the "var_dump"("test") syntax, attackers can bypass security checks and execute arbitrary PHP code, as exploited in the wild in May 2025.

Affected products
