Description

From ticket:153#comment:93

Again, if you discover any leak of e-mails information remaining for unauthorized users, please create a new ticket.

A malicious user with a little motivation could easily harvest 100's of email addresses from Trac. This can be achieved through custom queries on user-fields, using popular domain names as search criteria.

Example: hotmail.com

By replacing "…" with the domain name in question, full email addresses can be collected from the query results by unauthorized users.

Well, this is not a leak in the way I meant it in #153: there, I was referring to places missing the obfuscation.

Here you point to a limitation of the obfuscation scheme itself, the fact that you could gather a list of obfuscated e-mail addresses using a custom query is only anecdotal, as one can also imagine the spammer spidering a whole Trac site and looking for all the …@… strings.

So I don't think it's worth special casing this custom query, but OTOH, it might be useful to improve our obfuscation strategy. Suggestions welcome ;-)
