Security Notice 2026-05

SimpleHelp 5.5 and 6.0 Security Fix

This page provides SimpleHelp releases that address a security
vulnerability in v5.5.x and the prerelease of 6.0. Action is required
to ensure your server is secure.

SimpleHelp servers running versions 5.5.15 and earlier releases may be
subject to a vulnerability which can be exploited in specific
conditions depending on the server's settings and network context: Not
all servers can be exploited. If you have already taken all the
recommended measures in our security guide, practical malicious
exploitation is much more difficult but please update to a secure
release as soon as possible.

Full details of this vulnerability, including impact and
characteristics of compromise will be published shortly in
our disclosure document. Our current focus is on reaching
customers and encouraging them to update.

This page contains two downloads:

    SimpleHelp 5.5.16 - for users on v5.5.x.
    SimpleHelp 6.0 RC2 - for users on v6.0.

Please download and install the appropriate update to ensure
continued security.
