Impact
The mail obfuscation configuration was not fully taken into account and while the mail displayed to the end user was obfuscated:
- the rest response was also containing the mail unobfuscated
- user were able to filter and sort on the unobfuscated (allowing to infer the mail content)
The consequence was the possibility to retrieve the email addresses of all users even when obfuscated.
See https://jira.xwiki.org/browse/XWIKI-20333 for the reproduction steps.
