{"id":"CVE-2025-62168","state":"PUBLISHED","title":"Squid vulnerable to information disclosure via authentication credential leakage in error handling","description":"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.","publishedAt":"2025-10-17T16:21:30.156Z","updatedAt":"2026-02-26T16:57:24.141Z","severity":{"score":10,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["squid-cache squid"],"affected":[{"vendor":"squid-cache","product":"squid","versions":[{"version":"< 7.2","status":"affected"}]}],"references":["https://github.com/squid-cache/squid/security/advisories/GHSA-c8cc-phh7-xmxr","https://github.com/squid-cache/squid/commit/0951a0681011dfca3d78c84fd7f1e19c78a4443f","http://www.openwall.com/lists/oss-security/2025/11/05/6"],"weaknesses":["CWE-209","CWE-550"],"ingestedAt":"2026-10-29T20:09:48.677Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/62xxx/CVE-2025-62168.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-62168","state":"PUBLISHED","datePublished":"2025-10-17T16:21:30.156Z","dateUpdated":"2026-02-26T16:57:24.141Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-10-07T16:12:03.425Z"},"containers":{"cna":{"title":"Squid vulnerable to information disclosure via authentication credential leakage in error handling","descriptions":[{"lang":"en","value":"Squid is a caching proxy for the Web.
