        CVE ID:  CVE-2026-45180
  Distribution:  Catalyst-Plugin-Statsd
      Versions:  through 0.10.0

Catalyst::Plugin::Statsd versions through 0.10.0 for Perl may leak
session ids

Description
-----------
Catalyst::Plugin::Statsd versions through 0.10.0 for Perl may leak
session ids.

If the communication channel to the statsd daemon is not secured (for
example, by sending UDP packets to a host on another network), then
users' session ids may be leaked.  This may allow an attacker to use
session ids as authentication tokens.

Problem types
-------------
- CWE-319 Cleartext Transmission of Sensitive Information

Workarounds
-----------
Use a statsd daemon on the same host or through a secure communications
channel.


Solutions
---------
Upgrade to version 0.10.0 of later, which will no longer log session
ids to statsd.

If Plack::Middleware::Statsd is upgraded to 0.9.0 or later and is
configured to log some information securely, then session ids will be
logged as HMAC signatures instead.
