Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

to version 2.43.0 or higher.
Affected versions of this package are vulnerable to Improper Authentication such that API clients can craft a malicious X-HTTP-Method-Override
header value to bypass JWT authentication in specific cases.
ESPv2 allows malicious requests to bypass authentication if both conditions are true:
google.api.http
proto annotationsX-HTTP-Method-Override
is a valid HTTP method in the API service definition. ESPv2 will forward the request to your backend without checking the JWT.Note: Restricting API access with API keys works as intended and is not affected by this vulnerability.
