We updated the default permissions for noreply.properties set during package installation.
No publicly available exploits are known.
Local system users could read potentially sensitive information.
Attackers can successfully request arbitrary snippet IDs, including E-Mail signatures of other users within the same context.

We now drop all control characters that are not whitespace character during the export.
No publicly available exploits are known.
This allowed attackers to include unexpected content via user feedback and potentially break the exported data structure.
IPv4-mapped IPv6 addresses did not get recognized as "local" by the code and a connection attempt is made.

We now respect possible IPV4-mapped IPv6 addresses when checking if contained in a deny-list.
No publicly available exploits are known.
Attackers with access to user accounts could use this to bypass existing deny-list functionality and trigger requests to restricted network infrastructure to gain insight about topology and running services.
When adding an external mail account, processing of SMTP "capabilities" responses are not limited to plausible sizes.

We now limit accepted SMTP server response to reasonable length/size.
No publicly available exploits are known.
Attacker with access to a rogue SMTP service could trigger requests that lead to excessive resource usage and eventually service unavailability.
When adding an external mail account, processing of IMAP "capabilities" responses are not limited to plausible sizes.

We have improved existing content filters and validators to avoid including any local resources.
No publicly available exploits are known.
Attackers could discover restricted network topology and services as well as including local files with read permissions of the open-xchange system user. This was limited to specific file-types, like images.
Attackers with access to the "documentconverterws" API were able to inject serialized Java objects, that were not properly checked during deserialization. Access to this API endpoint is restricted to local networks by default.

A check has been introduced to restrict processing of legal and expected classes for this API. We now log a warning in case there are attempts to inject illegal classes.
No publicly available exploits are known.
Arbitrary code could be injected that is being executed when processing the request.
