Eval-Injection

An eval injection vulnerability, identified as CVE-2026-61511, exists in vBulletin versions 5.x through 5.7.5 and 6.x through 6.2.1, specifically within the vB5_Template_Runtime::runMaths() method, allowing unauthenticated remote attackers to achieve arbitrary PHP code execution by manipulating the pagenav[pagenumber] parameter through the unauthenticated ajax/render template route with phpfuck-style encoding.

An eval injection vulnerability exists in the nltk.collocations module of NLTK (Natural Language Toolkit) versions prior to 3.9.3, allowing an attacker to exploit this by controlling command-line arguments passed to collocations.py, which are then unsafely passed to eval() enabling remote code execution on the affected system.

Chamilo LMS versions prior to 2.0.0-RC.3 are vulnerable to remote code execution (RCE) via eval injection, where an authenticated administrator can inject arbitrary PHP code into platform settings that is then executed when any user (including unauthenticated) requests the /platform-config/list endpoint.
