CVE-2026-100187: AIL Framework Onion module crawler task injection

CVE-2026-100187 · Severity: info · Published 2026-09-25

The AIL Framework's Onion module is a web crawler designed to search Tor hidden services. It contained a flaw in how it validated .onion domain targets: the module accepted any URL with a 69-character length and ending in ".onion", without checking if the domain was actually a valid Tor address. An attacker could embed crafted URLs containing IP addresses or regular hostnames in web content that the framework crawls, and these would be accepted as legitimate Tor targets, causing the crawler to scan unintended network resources and potentially disrupting its operations or directing it toward attacker-controlled systems.

Technical details

The vulnerability is an insufficient input validation in the Onion module's URL extraction logic, specifically a length-based and suffix-based shortcut that bypassed hostname parsing and onion-domain validation. An unauthenticated attacker can inject arbitrary target URLs into the crawler task queue by publishing crafted content in locations the framework crawls, with no user interaction required. This results in a loss of integrity in crawler target selection, forcing the framework to process non-.onion targets. A patch exists that removes the shortcut and requires proper hostname parsing and validation before queuing crawler tasks.
