Versions prior to 1.0.19 are vulnerable to unauthenticated blind server-side request forgery (SSRF). The `testslack` request handler in `medusa/server/web/home/handler.py` does not validate the user-controlled `slack_webhook` variable and passes it to the `notifiers.slack_notifier.test_notify` method, then `_notify_slack` and finally `_send_slack` method,  which sends a POST request to the user-controlled URL on line 103 in `/medusa/notifiers/slack.py`, which leads to a blind server-side request forgery (SSRF). This issue allows for crafting POST requests on behalf of the Medusa server. Version 1.0.19 contains a fix for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-918"],"references":["https://github.com/pymedusa/Medusa/blob/3d656652ab277e47689483912ed7fc443e7023e8/medusa/notifiers/slack.py#L103","https://github.com/pymedusa/Medusa/blob/3d656652ab277e47689483912ed7fc443e7023e8/medusa/server/web/home/handler.py#L168","https://github.com/pymedusa/Medusa/releases/tag/v1.0.19","https://github.com/pymedusa/Medusa/security/advisories/GHSA-8mcr-vffr-jwxv","https://securitylab.github.com/advisories/GHSL-2023-201_GHSL-2023-202_Medusa/"],"products":["pymedusa:medusa"],"source":"nvd","synced_at":"2026-10-19T21:43:38.875533635+00:00"},"epss":{"cve":"CVE-2023-50259","score":0.00602,"percentile":0.48791,"date":"2026-10-31"},"kev":null,"osv":[],"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).
