Prior to version 4.9.1, endpoints/currency/update_exchange.php loads the first Fixer/API Layer credential globally instead of loading the credential for the authenticated user. As a result, a normal authenticated user without their own provider key can trigger exchange-rate refreshes using another user's stored provider credential. This issue has been patched in version 4.9.1.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
