Prior to 4.4.21, 4.5.14, 4.6.4, and 4.7.0-beta.1, the administrative statistics endpoints handled by Api::V1::Admin::MeasuresController and Api::V1::Admin::RetentionController checked authorization only after beginning expensive calculations. Anonymous callers could submit keys, start_at, and end_at parameters that caused long-running SQL queries in Admin::Metrics::Measure, Admin::Metrics::Retention, and Admin::Metrics::Dimension::BaseDimension, allowing repeated requests to exhaust server resources. This issue is fixed in versions 4.4.21, 4.5.14, 4.6.4, and 4.7.0-beta.1.","published":"2026-08-10T22:17:10.193","modified":"2026-08-10T22:17:10.193","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/mastodon/mastodon/commit/18c61f286f1f5718a8f517940ba384866ffa3892","label":"mastodon/mastodon@18c61f2"},"references":[{"type":"WEB","url":"https://github.com/mastodon/mastodon/commit/18c61f286f1f5718a8f517940ba384866ffa3892"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/commit/467c933459c7d0e5513475b9e4888afaedfb1074"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/commit/930aa9fee26bf9eaefe27826fa1061288d83373b"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/commit/da47a1bd3cd07935d7ca55a1f4f1a76f7f167e0d"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/releases/tag/v4.4.21"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/releases/tag/v4.5.14"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/releases/tag/v4.6.4"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/releases/tag/v4.7.0-beta.1"},{"type":"WEB","url":"https://github.com/mastodon/mastodon/security/advisories/GHSA-7jvv-fhmg-wpfw"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-10T22:17:10.193"}}
