{"cve":"CVE-2025-61783","nvd":{"published":"2025-10-09T21:15:40.127","modified":"2026-10-08T13:10:00.200","status":"Deferred","description":"Python Social Auth is a social authentication/registration mechanism. In versions prior to 5.6.0, upon authentication, the user could be associated by e-mail even if the `associate_by_email` pipeline was not included. This could lead to account compromise when a third-party authentication service does not validate provided e-mail addresses or doesn't require unique e-mail addresses. Version 5.6.0 contains a patch. As a workaround, review the authentication service policy on e-mail addresses; many will not allow exploiting this vulnerability.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":6.3},"cvss_v3":null,"cwes":["CWE-303"],"references":["https://github.com/python-social-auth/social-app-django/commit/10c80e2ebabeccd4e9c84ad0e16e1db74148ed4c","https://github.com/python-social-auth/social-app-django/issues/220","https://github.com/python-social-auth/social-app-django/issues/231","https://github.com/python-social-auth/social-app-django/issues/634","https://github.com/python-social-auth/social-app-django/pull/803"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-61783","score":0.00542,"percentile":0.45281,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-wv4w-6qv2-qqfg","url":"https://osv.dev/vulnerability/GHSA-wv4w-6qv2-qqfg","summary":"Python Social Auth - Django has unsafe account association ","modified":"2026-07-07T17:57:30.314209096Z","packages":[{"ecosystem":"PyPI","name":"social-auth-app-django","purl":"pkg:pypi/social-auth-app-django","ranges":["<5.6.0"],"fixed":["5.6.0"]}]},{"id":"PYSEC-2026-1932","url":"https://osv.dev/vulnerability/PYSEC-2026-1932","summary":"Python Social Auth - Django has unsafe account association ","modified":"2026-07-07T17:47:08.745637805Z","packages":[{"ecosystem":"PyPI","name":"social-auth-app-django","purl":"pkg:pypi/social-auth-app-django","ranges":["<5.6.0"],"fixed":["5.6.0"]}]}],"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).
