{"cve":"CVE-2022-41913","nvd":{"published":"2022-11-14T21:15:18.320","modified":"2026-06-17T05:04:03.073","status":"Modified","description":"Discourse-calendar is a plugin for the Discourse messaging platform which adds the ability to create a dynamic calendar in the first post of a topic. Members of private groups or public groups with private members can be listed by users, who can create and edit post events. This vulnerability only affects sites which have discourse post events enabled. This issue has been patched in commit `ca5ae3e7e` which will be included in future releases. Users unable to upgrade should disable the `discourse_post_event_enabled` setting to fully mitigate the issue. Also, it's possible to prevent regular users from using this vulnerability by removing all groups from the `discourse_post_event_allowed_on_groups` but note that moderators will still be able to use it.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-200"],"references":["https://github.com/discourse/discourse-calendar/commit/ca5ae3e7e0c2b32af5ca4ec69c95e95b2ecef2e9","https://github.com/discourse/discourse-calendar/security/advisories/GHSA-jh96-w279-g7r9","https://github.com/discourse/discourse-calendar/commit/ca5ae3e7e0c2b32af5ca4ec69c95e95b2ecef2e9","https://github.com/discourse/discourse-calendar/security/advisories/GHSA-jh96-w279-g7r9"],"products":["discourse:calendar"],"source":"nvd","synced_at":"2026-10-19T21:37:08.729216836+00:00"},"epss":{"cve":"CVE-2022-41913","score":0.00425,"percentile":0.36783,"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).
