Name of the Vulnerable Software and Affected Versions Squid versions 2.5 and earlier

Description The issue allows remote authenticated users to bypass username-based Access Control Lists (ACLs) by using a username with a space at the beginning or end. This is possible because the LDAP server ignores such spaces in usernames.

Recommendations For Squid versions 2.5 and earlier, consider updating to a version where this issue is fixed, or as a temporary workaround, restrict the use of usernames with leading or trailing spaces to minimize the risk of exploitation.
