Prior to version 3.0.2 of the `stable` branch and version 3.1.0.beta3 of the `beta` and `tests-passed` branches, a user logged as an administrator can request backups multiple times, which will eat up all the connections to the DB. If this is done on a site using multisite, then it can affect the whole cluster. The vulnerability is patched in version 3.0.2 of the `stable` branch and version 3.1.0.beta3 of the `beta` and `tests-passed` branches. There are no known workarounds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","score":4.9},"cwes":["CWE-770"],"references":["https://github.com/discourse/discourse/commit/0bd64788d2b4680c04fbef76314a24884d65fed9","https://github.com/discourse/discourse/commit/78a3efa7104eed6dd3ed7a06a71e2705337d9e61","https://github.com/discourse/discourse/pull/20700","https://github.com/discourse/discourse/pull/20701","https://github.com/discourse/discourse/security/advisories/GHSA-cp7c-fm4c-6xxx"],"products":["discourse:discourse"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-28107","score":0.00652,"percentile":0.51246,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
