Threat Intelligence
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.

CVE-2025-14505 (opens in a new tab)How to fix?
There is no fixed version for elliptic.
Overview
elliptic is a fast elliptic-curve cryptography implementation in plain javascript.
Affected versions of this package are vulnerable to Use of a Cryptographic Primitive with a Risky Implementation due to the incorrect computation of the byte-length of k value with leading zeros resulting in its truncation. An attacker can obtain the secret key by analyzing both a faulty signature generated by a vulnerable implementation and a correct signature for the same inputs.
Note:
There is a distinct but related issue CVE-2024-48948.
