{"cve":"CVE-2023-28117","nvd":{"published":"2023-03-22T20:15:12.793","modified":"2026-06-17T05:46:54.547","status":"Modified","description":"Sentry SDK is the official Python SDK for Sentry, real-time crash reporting software. When using the Django integration of versions prior to 1.14.0 of the Sentry SDK in a specific configuration it is possible to leak sensitive cookies values, including the session cookie to Sentry. These sensitive cookies could then be used by someone with access to your Sentry issues to impersonate or escalate their privileges within your application.\n\nIn order for these sensitive values to be leaked, the Sentry SDK configuration must have `sendDefaultPII` set to `True`; one must use a custom name for either `SESSION_COOKIE_NAME` or `CSRF_COOKIE_NAME` in one's Django settings; and one must not be configured in one's organization or project settings to use Sentry's data scrubbing features to account for the custom cookie names.\n\nAs of version 1.14.0, the Django integration of the `sentry-sdk` will detect the custom cookie names based on one's Django settings and will remove the values from the payload before sending the data to Sentry. As a workaround, use the SDK's filtering mechanism to remove the cookies from the payload that is sent to Sentry. For error events, this can be done with the `before_send` callback method and for performance related events (transactions) one can use the `before_send_transaction` callback method. Those who want to handle filtering of these values on the server-side can also use Sentry's advanced data scrubbing feature to account for the custom cookie names. Look for the `$http.cookies`, `$http.headers`, `$request.cookies`, or `$request.headers` fields to target with a scrubbing rule.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-201","CWE-209"],"references":["https://github.com/getsentry/sentry-python/pull/1842","https://github.com/getsentry/sentry-python/releases/tag/1.14.0","https://github.com/getsentry/sentry-python/security/advisories/GHSA-29pr-6jr8-q5jm","https://github.com/getsentry/sentry-python/pull/1842","https://github.com/getsentry/sentry-python/releases/tag/1.14.0"],"products":["sentry:sentry_software_development_kit"],"source":"nvd","synced_at":"2026-10-19T21:37:48.383111019+00:00"},"epss":{"cve":"CVE-2023-28117","score":0.00647,"percentile":0.51011,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-29pr-6jr8-q5jm","url":"https://osv.dev/vulnerability/GHSA-29pr-6jr8-q5jm","summary":"Sentry SDK leaks sensitive session information when `sendDefaultPII` is set to `True`","modified":"2026-09-10T03:49:52.267764630Z","packages":[{"ecosystem":"PyPI","name":"sentry-sdk","purl":"pkg:pypi/sentry-sdk","ranges":["<1.14.0"],"fixed":["1.14.0"]}]},{"id":"PYSEC-2026-920","url":"https://osv.dev/vulnerability/PYSEC-2026-920","summary":"Sentry SDK leaks sensitive session information when `sendDefaultPII` is set to `True`","modified":"2026-07-07T11:45:22.029710566Z","packages":[{"ecosystem":"PyPI","name":"sentry-sdk","purl":"pkg:pypi/sentry-sdk","ranges":["<1.14.0"],"fixed":["1.14.0"]}]}],"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).
