{"schemaVersion":3,"id":"CVE-2026-50637","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Metrics::Any::Adapter::Statsd versions before 0.04 for Perl does not protect against metric injections.\n\nThe statsd protocol (and extensions) allow mutiple metrics, separated by newlines, to be sent per packet.\n\nThe send method does not validate the contents of the metric names or values. If the names have newlines and statsd control characters (colon, pipe) then metric injections are possible.\n\nVersion 0.04 fixed this by modifying the _make method to block metric names with characters below ASCII 32 (which includes the newline), or colons or pipes.","dates":{"published":"2026-06-10T18:32:11.614Z","modified":"2026-06-19T15:32:41.370Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.2,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.2,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.2,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00503,"percentile":0.42114,"severity":"low","asOf":"2026-10-22T00:00:00.000Z","change":{"pp":0.18,"baselineDate":"2026-09-22T00:00:00.000Z","baselineScore":0.00323},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-22T00:00:00.000Z","score":0.00503,"percentile":0.42114}],"last30":[{"date":"2026-09-22T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00323,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00503,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":
