Prior to version 3.1.3 of the `stable` branch and version 3.2.0.beta3 of the `beta` and `tests-passed` branches, if a user has been quoted and uses a `|` in their full name, they might be able to trigger a bug that generates a lot of duplicate content in all the posts they've been quoted by updating their full name again. Version 3.1.3 of the `stable` branch and version 3.2.0.beta3 of the `beta` and `tests-passed` branches contain a patch for this issue. No known workaround exists, although one can stop the \"bleeding\" by ensuring users only use alphanumeric characters in their full name field.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":5.4},"cwes":["CWE-1333"],"references":["https://github.com/discourse/discourse/commit/2ec25105179199cf80912bf011c18b8b870e1863","https://github.com/discourse/discourse/commit/7d484864fe91ff79c478f57e7ddb1235d701921e","https://github.com/discourse/discourse/security/advisories/GHSA-hcgf-hg2g-mw78","https://github.com/discourse/discourse/commit/2ec25105179199cf80912bf011c18b8b870e1863","https://github.com/discourse/discourse/commit/7d484864fe91ff79c478f57e7ddb1235d701921e"],"products":["discourse:discourse"],"source":"nvd","synced_at":"2026-10-19T21:42:07.670898610+00:00"},"epss":{"cve":"CVE-2023-45806","score":0.00999,"percentile":0.62784,"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).
