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.

Test your applicationsUpgrade aiohttp
to version 3.8.0 or higher.
Affected versions of this package are vulnerable to Inconsistent Interpretation of HTTP Messages due to the inconsistent interpretation of Content-Length
vs. Transfer-Encoding
in both C and Python fallbacks. An attacker can bypass proxy rules and poison sockets to other users, potentially passing Authentication Headers.
Note:
This is only exploitable if a configuration with a reverse proxy that accepts both Content-Length
and Transfer-Encoding
headers and aiohttp as backend is present.
Additionally, if an Open Redirect is present, it can be combined to redirect random users to an attacker's website and log the request.
