CVE-2026-67354— guzzlehttp/guzzle before 7.15.1 URI Fragment Disclosure via Referer

guzzlehttp/guzzle before 7.15.1 URI Fragment Disclosure via Referer

guzzlehttp/guzzle versions before 7.15.1 contain an information disclosure vulnerability in RedirectMiddleware. When the optional allow_redirects.referer setting is enabled, the middleware copies the URI fragment (the portion after '#') from the referring request into the generated Referer header when following a same-scheme redirect (e.g., HTTPS to HTTPS). An attacker who controls the redirect destination can read this fragment from the incoming Referer header, potentially disclosing one-time login secrets, access tokens, state values, or other sensitive client data to a server never meant to receive it. The referer setting is disabled by default. Fixed in 7.15.1, which strips the fragment before generating the Referer value.

通过发送数据的信息暴露

Guzzle 信息泄露漏洞

guzzle guzzle是guzzle组织的一款用于简化HTTP请求的PHP开发工具。 Guzzle 7.15.1之前版本存在信息泄露漏洞，该漏洞源于RedirectMiddleware在启用allow_redirects.referer设置时，将URI片段复制到生成的Referer标头，攻击者可通过控制重定向目标读取该片段，可能导致一次性登录密钥、访问令牌、状态值等敏感数据泄露。
