Given the following situation: the Crowd application is bound to directory 1 and has a user called admin and the Google Apps application is bound to directory 2, which also has a user called admin, it was possible to authenticate REST requests using the credentials of the user coming from directory 2 and impersonate the user from directory 1.","published_at":"2018-01-31T14:00:00Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-863"],"nvd_references":["https://jira.atlassian.com/browse/CWD-5009"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:09:44.731718Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"atlassian","vendor_name":"Atlassian","product_slug":"crowd","product_name":"Crowd","version_start":"from 1.5.0 before 3.1.2","version_start_inclusive":true,"version_end":"from 1.5.0 before 3.1.2","version_end_inclusive":true,"cpe23_uri":"cve5:atlassian:crowd:from 1.5.0 before 3.1.2:from 1.5.0 before 3.1.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://jira.atlassian.com/browse/CWD-5009","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2018-01-31T14:00:00Z","label":"CVE published","source":null}]}
