Security advisory

This release contains fixes to the following security issues:

• Denial of service attack via disk space or memory exhaustion (CVE-2021-29430).
• SSRF due to missing validation of hostnames (CVE-2021-29431).
• Malicious users could control the content of invitation emails (CVE-2021-29432).
• Denial of service (via resource exhaustion) due to improper input validation (CVE-2021-29433).

Although we are not aware of these vulnerabilities being exploited in the wild, Sydent server administrators are advised to update as soon as possible. Note that as well as changes to the package, there are also changes to the default email templates. If any templates have been updated locally, they must also be updated in line with the changes to the defaults for full protection from CVE-2021-29432.

Features

• Accept an optional web_client_location argument to the invite endpoint which allows customisation of the email template. (#326)
• Move templates to a per-brand subdirectory of /res. Add templates.path and brand.default config options. (#328)
