{"id":"CVE-2025-62168","url":"https://www.cyber-defence.io/tools/cve/CVE-2025-62168","generatedAt":"2026-10-28T02:24:57.492Z","title":"In Squid versions prior to 7.2, a failure to redact HTTP authentication credentials in error handling allows information disclosure.","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.","published":"2025-10-17T17:15:49.000Z","lastModified":"2026-10-19T16:10:00.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-209","CWE-550"],"affected":["squid-cache/squid"],"epss":{"score":0.6336,"percentile":0.99202,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 63.4%, higher than 99% of all known CVEs.
