Doc Text:	A Information Disclosure vulnerability has been identified in the Squid web caching proxy. This flaw occurs when the application fails to properly redact sensitive Hypertext Transfer Protocol (HTTP) authentication credentials from an error response. A remote client can exploit this by triggering an error condition, which allows a malicious script to bypass browser security and disclose the username and password a trusted client uses for access. This directly compromises the security of internal application credentials and security tokens, especially when Squid is configured for backend load balancing.	Story Points:	---

Description OSIDB Bzimport 2025-10-17 17:02:18 UTC

Squid is a caching proxy for the Web. In Squid versions prior to 7.2, a failure to redact HTTP authentication credentials in error handling allows information disclosure. The vulnerability allows a script to bypass browser security protections and learn the credentials a trusted client uses to authenticate. This potentially allows a remote client to identify security tokens or credentials used internally by a web application using Squid for backend load balancing. These attacks do not require Squid to be configured with HTTP authentication. The vulnerability is fixed in version 7.2. As a workaround, disable debug information in administrator mailto links generated by Squid by configuring squid.conf with email_err_data off.
