Attackers can confirm the DNI via the oracle, brute-force the date of birth and IBAN digits, obtain the phone number through open-source intelligence, then submit an attacker-controlled email field so the password reset link is delivered to them, enabling full account takeover including profile data, full IBAN, and fiscal documents.\nhttps://www.cve.org/CVERecord?id=CVE-2026-53997https://beafn28.es/articulos/cve-2026-53997https://netherman.app/https://www.vulncheck.com/advisories/netherman-portal-del-hermano-account-takeover-via-password-reset-oracle#netherman #NetHerman #PortaldelHermano(portaldelhermano.es)#CVE_2026_53997#bot", "url": "https://infosec.exchange/users/cve/statuses/117429920249136999"}, {"timestamp": "2026-10-12T21:17:17Z", "date_only": false, "value": "2026-10-12T21:17:17Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-P44J-P338-FFRC", "record": "GHSA-P44J-P338-FFRC", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-12T21:17:17.400Z", "date_only": false, "value": "2026-10-12T21:17:17.400", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-53997", "record": "FKIE_CVE-2026-53997", "field": "published"}, {"timestamp": "2026-10-12T21:32:01Z", "date_only": false, "value": "2026-10-12T21:32:01Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-P44J-P338-FFRC", "record": "GHSA-P44J-P338-FFRC", "field": "published"}, {"timestamp": "2026-10-12T21:32:01Z", "date_only": false, "value": "2026-10-12T21:32:01Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-P44J-P338-FFRC", "record": "GHSA-P44J-P338-FFRC", "field": "modified"}, {"timestamp": "2026-10-12T21:40:05.233Z", "date_only": false, "value": "2026-10-12T21:40:05.233119Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/stackflag.bsky.social/post/3mxpi7btvwe2w", "record": "CVE-2026-53997", "field": "creation_timestamp", "uuid": "fe3973b5-41fb-44eb-97a3-9bd0e47a35cb", "content": "CVE-2026-53997 - portal del hermano (portaldelhermano.es)\nThe password\u2011reset feature on netherman/portal del hermano can be abused to take over any user\u2019s account.
