CVE-2026-50638 | Metrics::Any::Adapter::DogStatsd versions before 0.04 for Perl does not protect against metric injections

Metrics::Any::Adapter::DogStatsd versions before 0.04 for Perl does not protect against metric injections. The statsd protocol (and extensions such as dogstatsd) allow mutiple metrics, separated by newlines, to be sent per packet. Metrics::Any::Adapter::DogStatsd which extends Metrics::Any::Adapter::Statsd, which has a similar vulnerability. In addition, the _tags function does not check tags for newlines or statsd control characters. The tags can be used for metric injections.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
