The django_ses library implements a mail backend for Django using AWS Simple Email Service. The library exports the `SESEventWebhookView class` intended to receive signed requests from AWS to handle email bounces, subscriptions, etc. These requests are signed by AWS and are verified by django_ses, however the verification of this signature was found to be flawed as it allowed users to specify arbitrary public certificates. This issue was patched in version 3.5.0.","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-347"],"references":["https://github.com/django-ses/django-ses/blob/3d627067935876487f9938310d5e1fbb249a7778/CVE/001-cert-url-signature-verification.md","https://github.com/django-ses/django-ses/commit/b71b5f413293a13997b6e6314086cb9c22629795","https://github.com/django-ses/django-ses/security/advisories/GHSA-qg36-9jxh-fj25","https://github.com/django-ses/django-ses/blob/3d627067935876487f9938310d5e1fbb249a7778/CVE/001-cert-url-signature-verification.md","https://github.com/django-ses/django-ses/commit/b71b5f413293a13997b6e6314086cb9c22629795"],"products":["django-ses_project:django-ses"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-33185","score":0.00233,"percentile":0.14296,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qg36-9jxh-fj25","url":"https://osv.dev/vulnerability/GHSA-qg36-9jxh-fj25","summary":"Incorrect signature verification in django-ses","modified":"2026-09-10T03:50:08.393095928Z","packages":[{"ecosystem":"PyPI","name":"django-ses","purl":"pkg:pypi/django-ses","ranges":["<3.5.0"],"fixed":["3.5.0"]}]},{"id":"PYSEC-2023-82","url":"https://osv.dev/vulnerability/PYSEC-2023-82","summary":"","modified":"2023-11-08T04:12:39.443618Z","packages":[{"ecosystem":"PyPI","name":"django-ses","purl":"pkg:pypi/django-ses","ranges":["<3.5.0"],"fixed":["3.5.0"]}]}],"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).
