Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Prowler versions before 5.30.3 are vulnerable (prowler-cloud package). In the SAML sign-in flow, the token could be issued for the tenant derived from the asserted email domain rather than the tenant whose SAML configuration was validated. An attacker who controls a tenant with its own SAML configuration and IdP could possibly obtain a token for another tenant. Upgrade to prowler-cloud 5.30.3 or later.
