{"cve":"CVE-2026-59151","nvd":{"published":"2026-07-10T19:17:26.780","modified":"2026-10-25T15:10:00.147","status":"Analyzed","description":"Prowler is a cloud security platform. Prior to 5.30.3, Prowler's SAML authentication flow trusted the email domain asserted in a SAMLResponse when deciding which tenant should receive the final token, and the ACS finish logic in api/src/backend/api/v1/views.py recalculated the tenant from user.email instead of binding token issuance to the validated SAML configuration. An authenticated attacker with a controlled SAML IdP could complete a valid SAML flow for an attacker-controlled domain while asserting an email address from another configured domain, causing a SAMLToken and tenant-scoped JWT to be issued for the wrong tenant and enabling cross-tenant account takeover. This issue is fixed in version 5.30.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","score":9.6},"cwes":["CWE-287"],"references":["https://github.com/prowler-cloud/prowler/commit/bf3b5c2ba713e533014927141b64948c82c8f32e","https://github.com/prowler-cloud/prowler/commit/f5ff30ad175bd2edf02cd28872653c1cda5867b7","https://github.com/prowler-cloud/prowler/pull/11650","https://github.com/prowler-cloud/prowler/releases/tag/5.30.3","https://github.com/prowler-cloud/prowler/security/advisories/GHSA-h8m9-jgf8-vwvp"],"products":["prowler:prowler"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-59151","score":0.00534,"percentile":0.44771,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-h8m9-jgf8-vwvp","url":"https://osv.dev/vulnerability/GHSA-h8m9-jgf8-vwvp","summary":"Prowler: SAML Domain Claiming Enables Cross-Tenant Account Takeover","modified":"2026-10-15T02:55:47.735531350Z","packages":[{"ecosystem":"PyPI","name":"prowler-cloud","purl":"pkg:pypi/prowler-cloud","ranges":["<5.30.3"],"fixed":["5.30.3"]}]},{"id":"PYSEC-2026-3725","url":"https://osv.dev/vulnerability/PYSEC-2026-3725","summary":"","modified":"2026-10-15T02:55:47.735531350Z","packages":[{"ecosystem":"PyPI","name":"prowler-cloud","purl":"pkg:pypi/prowler-cloud","ranges":["<5.30.3"],"fixed":["5.30.3"]}]}],"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).
