The sesskey can be obtained without authentication and reused within the OAuth2 login flow, resulting in the victim's session being linked to the attacker's. Successful exploitation results in full account takeover. According to the Moodle Releases page, \"Bug fixes for security issues in 3.11.x ended 11 December 2023.\" NOTE: This vulnerability only affects products that are no longer supported by the maintainer.\n\ud83d\udccf Published: 2025-06-24T00:00:00.000Z\n\ud83d\udccf Modified: 2025-06-24T19:22:54.821Z\n\ud83d\udd17 References:\n1. https://rentry.co/moodle-oauth2-cve\n2. https://github.com/moodle/moodle/releases/tag/v3.11.18\n3. https://moodledev.io/general/releases#moodle-311", "url": "https://t.me/DarkWebInformer_CVEAlerts/19393"}, {"timestamp": "2025-06-24T20:15:00Z", "date_only": false, "value": "2025-06-24T20:15:00Z", "kind": "milestone", "label": "Published", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2025-53021", "record": "UBUNTU-CVE-2025-53021", "field": "published"}, {"timestamp": "2025-06-24T20:15:26Z", "date_only": false, "value": "2025-06-24T20:15:26Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-CGVV-3455-824J", "record": "GHSA-CGVV-3455-824J", "field": "database_specific.nvd_published_at"}, {"timestamp": "2025-06-24T20:15:26.867Z", "date_only": false, "value": "2025-06-24T20:15:26.867", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2025-53021", "record": "FKIE_CVE-2025-53021", "field": "published"}, {"timestamp": "2025-06-24T21:30:29Z", "date_only": false, "value": "2025-06-24T21:30:29Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-CGVV-3455-824J", "record": "GHSA-CGVV-3455-824J", "field": "published"}, {"timestamp": "2025-06-24T22:00:00Z", "date_only": false, "value": "2025-06-24T22:00:00.000+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_certbund \u00b7 WID-SEC-W-2025-1391", "record": "WID-SEC-W-2025-1391", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2025-06-24T22:00:00Z", "date_only": false, "value": "2025-06-24T22:00:00.000+00:00", "kind": "milestone", "label": "Published", "source": "csaf_certbund \u00b7 WID-SEC-W-2025-1391", "record": "WID-SEC-W-2025-1391", "field": "document.tracking.initial_release_date"}, {"timestamp": "2025-06-24T22:00:00Z", "date_only": false, "value": "2025-06-24T22:00:00.000+00:00", "kind": "other", "label": "Release date", "source": "csaf_certbund \u00b7 WID-SEC-W-2025-1391", "record": "WID-SEC-W-2025-1391", "field": "vulnerabilities.0.release_date"}, {"timestamp": "2025-06-24T22:00:00Z", "date_only": false, "value": "2025-06-24T22:00:00.000+00:00", "kind": "other", "label": "Updated", "source": "csaf_certbund \u00b7 WID-SEC-W-2025-1391", "record": "WID-SEC-W-2025-1391", "field": "document.tracking.current_release_date"}, {"timestamp": "2025-06-24T22:49:20.671Z", "date_only": false, "value": "2025-06-24T22:49:20.671298Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/3lsf6lsp7u72a", "record": "CVE-2025-53021", "field": "creation_timestamp", "uuid": "1dc71af4-e6ea-4707-89e2-dfba22605475", "url": "https://bsky.app/profile/cve.skyfleet.blue/post/3lsf6lsp7u72a"}, {"timestamp": "2025-06-25T10:10:44.328Z", "date_only": false, "value": "2025-06-25T10:10:44.328+00:00", "kind": "other", "label": "Document generated", "source": "csaf_certbund \u00b7 WID-SEC-W-2025-1391", "record": "WID-SEC-W-2025-1391", "field": "document.tracking.generator.date"}, {"timestamp": "2025-06-26T14:12:34Z", "date_only": false, "value": "2025-06-26T14:12:34Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-CGVV-3455-824J", "record": "GHSA-CGVV-3455-824J", "field": "modified"}, {"timestamp": "2025-07-10T06:00:29.762Z", "date_only": false, "value": "2025-07-10T06:00:29.762Z", "kind": "milestone", "label": "Published", "source": "bitnami_vulndb \u00b7 BIT-MOODLE-2025-53021", "record": "BIT-MOODLE-2025-53021", "field": "published"}, {"timestamp": "2026-06-17T09:37:29.393Z", "date_only": false, "value": "2026-06-17T09:37:29.393", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2025-53021", "record": "FKIE_CVE-2025-53021", "field": "lastModified"}, {"timestamp": "2026-09-08T08:34:36.952Z", "date_only": false, "value": "2026-09-08T08:34:36.952Z", "kind": "other", "label": "Updated", "source": "bitnami_vulndb \u00b7 BIT-MOODLE-2025-53021", "record": "BIT-MOODLE-2025-53021", "field": "modified"}, {"timestamp": "2026-09-23T15:59:10Z", "date_only": false, "value": "2026-09-23T15:59:10Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2025-53021", "record": "UBUNTU-CVE-2025-53021", "field": "modified"}]}
