Details

It was discovered that Mailman did not properly sanitize certain fields,
resulting in cross-site scripting (XSS) vulnerabilities. With cross-site
scripting vulnerabilities, if a user were tricked into viewing server
output during a crafted server request, a remote attacker could exploit
this to modify the contents, or steal confidential data, within the same
domain.
