建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
RansomLook 通过多个未经身份验证的 API 响应，泄露了敏感的操作者侧爬取配置。只要位置信息本身未被标记为“私密”，系统就会将关联于勒索软件组织及市场的地点记录，几乎原封不动地返回给未经身份验证的请求方。 这些记录可能包含内部字段，例如： ：可能包含用于访问被监控网站的认证头、会话 Cookie 或其他凭据； ：可能包含用于绕过验证码（CAPTCHA）、反机器人保护机制或付费墙的逻辑代码； ：披露了爬取环境的详细信息。 未经身份验证的远程攻击者可以查询受影响的 API 端点，从而获取上述敏感值。泄露的认证

Vulnerability Title
Unauthenticated Disclosure of Scraping Credentials and Bypass Configuration via RansomLook API
来源: CVE Program / CVE List V5
Vulnerability Description
RansomLook exposed sensitive operator-side scraping configuration through multiple unauthenticated API responses. Location records associated with ransomware groups and markets were returned largely verbatim to unauthenticated callers whenever the location itself was not marked as private.
These records could contain internal fields such as header, which may include authentication headers, session cookies, or other credentials used to access monitored websites; init_script, which may contain logic used to bypass CAPTCHA, anti-bot protections, or paywalls; and browser, which discloses details about the scraping environment.
An unauthenticated remote attacker could query the affected API endpoints and obtain these values. Leaked authentication material could potentially be replayed against the monitored service, while disclosure of scraping and bypass logic could allow site operators or other attackers to identify and defeat RansomLook's collection mechanisms.
The patch introduces an explicit allowlist of fields permitted in public location records and strips all operator-side fields before returning data to unauthenticated users.
The accompanying change from <string:postname> to <path:postname> appears to be a functional correction allowing legitimate post titles containing / and does not, based on this patch alone, represent the security issue.
