Threat Intelligence
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.

NewCVE-2026-31790 (opens in a new tab)How to fix?
Upgrade openssl to version 3.0.20, 3.3.7, 3.4.5, 3.5.6, 3.6.2 or higher.
Overview
Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions via the RSASVE encapsulation process. An attacker can obtain sensitive information by supplying an invalid RSA public key and triggering the use of uninitialized memory contents as ciphertext.
Note:
This is only exploitable if the application does not validate the RSA public key before encapsulation.
Workaround
This vulnerability can be mitigated by calling EVP_PKEY_public_check() or EVP_PKEY_public_check_quick() before EVP_PKEY_encapsulate().
