Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

AIL Framework 中的 Onion 模块在其 URL 提取逻辑中存在一个性能捷径，该逻辑仅通过长度检查（恰好 69 个字符）和后缀检查（以“.onion”结尾）就将 URL 视为有效的 .onion 目标，而未执行正确的 hostname 解析或 onion 域名验证。未认证的攻击者若能发布或控制由该框架爬取的 Web 内容，则可在其中嵌入精心构造的 URL，该 URL 包含一个 IP 地址或非 onion 主机名，其路径以“.onion”结尾，并满足上述长度和后缀条件。此类 URL 会被提取，其域名将从

Vulnerability Title
AIL Framework Onion Module: Non-Onion URL Accepted as Crawler Task Due to Bypassed Domain Validation
Source: CVE Program / CVE List V5
Vulnerability Description
The Onion module in AIL Framework contained a performance shortcut in its URL extraction logic that accepted URLs as valid .onion targets based solely on a length check (exactly 69 characters) and a suffix check (ending in ".onion"), without performing proper hostname parsing or onion-domain validation. An unauthenticated attacker who could publish or control web content crawled by the framework could embed a crafted URL containing an IP address or non-onion hostname with a path ending in ".onion" that satisfied the length and suffix conditions. Such a URL would be extracted, its domain naively sliced from the string, and queued as a legitimate onion crawler task. This allowed unauthenticated content publishers to inject arbitrary non-onion targets into the crawler's task queue, influencing crawler behavior and potentially directing it toward unintended network resources. The vulnerability required no authentication, no user interaction, and only the ability to place crafted content in a location the framework would crawl. The security impact is a loss of integrity in the crawler's target selection: the framework processes and acts upon URLs that do not correspond to legitimate .onion services.
