CVE-2026-66913— Lookyloo 资源管理错误漏洞

Zip Bomb in Lookyloo Capture Upload Allows Denial of Service

Lookyloo did not enforce limits on the decompressed size of uploaded capture archives and compressed HAR files. An attacker could submit a specially crafted ZIP, gzip, or zlib-compressed capture containing data that expands to a very large size during processing. Because the application decompressed this content directly in memory without first limiting the output size, processing the malicious capture could exhaust available memory, terminate a web or worker process, or make the Lookyloo instance unavailable. The vulnerability affects both full Lookyloo capture archive imports and API submissions containing gzip-compressed HAR data. Repeated exploitation could cause a persistent denial-of-service condition until the affected processes or instance are restarted. The patch introduces: * A 1 GB cumulative uncompressed-size limit for imported capture archives. * Size-limited gzip and zlib decompression for compressed HAR files. * Explicit detection and handling of suspected zip bombs. * An HTTP 400 response when an oversized compressed HAR file is submitted through the API.

未加控制的资源消耗(资源穷尽)

Lookyloo 资源管理错误漏洞

Lookyloo是Lookyloo组织开源的一个网站捕获工具。 Lookyloo 1.40.0及之前版本存在资源管理错误漏洞，该漏洞源于未对上传的捕获档案和压缩HAR文件的解压大小进行限制，直接解压内容到内存，可能耗尽可用内存，导致拒绝服务。
