HIGHPre-NVD 7.67.6—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Prowler is a cloud security platform. Prior to 5.33.1, an authenticated user with Lighthouse provider configuration access could 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. This issue is fixed in version 5.33.1.
