Summary
A vulnerability in Prowler before 5.30.3 allows an attacker to take over accounts in another tenant by manipulating the email address in a SAMLResponse. The system trusted the email domain from the SAMLResponse when selecting the tenant, instead of binding the token to the validated SAML configuration.
Risk Assessment
An attacker with a controlled SAML IdP can obtain a JWT for a different tenant, leading to cross-tenant account takeover and unauthorized access to cloud resources.
Recommendation
Immediately upgrade Prowler to version 5.30.3 or later. After upgrading, review the SAML configuration and ensure tokens are issued only for approved domains.

See all- CVE-2026-73263Critical
Prowler before version 5.36.0 in the Kubernetes provider connection test accepts kubeconfig_content containing a legacy gcp auth-provider with config.cmd-path and config.cmd-args. Checking only exec blocks in kubeconfig_contains_exec_auth and loading via config.load_kube_config_from_dict causes kubernetes-python CommandTokenSource.token to run the attacker-supplied command through subprocess.Popen on the shared worker.
- CVE-2026-73264High
Prowler before version 5.33.1 allows an authenticated user with Lighthouse provider configuration access to supply an unvalidated base_url for the openai_compatible provider through POST /api/v1/lighthouse/providers and POST /api/v1/lighthouse/providers/{id}/connection, causing api/src/backend/tasks/jobs/lighthouse_providers.py to send outbound requests, including the API key in the Authorization header, to attacker-controlled or internal endpoints when client.models.list was called.
- CVE-2026-73262Medium
In Prowler prior to 5.37.0, the HTML output formatter in prowler/lib/outputs/html/html.py inserted finding.resource_tags, assembled by unroll_dict and parse_html_string, into generated reports without HTML escaping, allowing a cloud principal who can modify a scanned resource tag to store HTML or JavaScript that executes when another user opens the report.
Original NVD description (English source)
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.
