Summary
A CWE-552 vulnerability in Easergy T300 firmware versions V2.7.1 and older allows unauthorized attackers to access system files and directories. Lack of proper access restrictions can lead to exposure of sensitive data.
Risk Assessment
The organization is at risk of leaking sensitive information such as device configurations or operational data, which could enable further attacks or compromise system integrity.
Recommendation
Immediately update Easergy T300 firmware to a version newer than V2.7.1 that includes a fix restricting file and directory access.

- CVE-2026-102268Critical
PyJWT is a Python implementation of JSON Web Token standards. Prior to version 2.14.0, is_pem_format in jwt/utils.py does not recognize every PEM representation accepted by the cryptography loader. When an application mixes HMAC and asymmetric algorithms and supplies a mutated public-key PEM as raw key bytes, HMACAlgorithm.prepare_key treats the unrecognized asymmetric public key as an HMAC secret. An attacker who knows the public key can forge authenticated HMAC tokens. This issue is fixed in version 2.14.0.
