CVE-2025-45764 Details
Description
jsrsasign v11.1.0 was discovered to contain weak encryption. NOTE: this issue has been disputed by a third party who believes that CVE IDs can be assigned for key lengths in specific applications that use a library, and should not be assigned to the default key lengths in a library. This dispute is subject to review under CNA rules 4.1.4, 4.1.14, and other rules; the dispute tagging is not meant to recommend an outcome for this CVE Record.
A vulnerability exists in jsrsasign version 11.1.0, where the encryption strength is inadequate. This issue arises because the HMAC and RSA key lengths used in the JSON Web Signature (JWS) implementation do not comply with recommended security standards. As a result, the vulnerability could potentially be exploited, leading to serious security risks.
Users can upgrade to jsrsasign version 11.1.0 or later to address this vulnerability.
