HighCVSS 7.8Exploitation Probability (EPSS)
High risk88th percentile - higher than 88% of all known CVEs
Summary
Multiple out-of-bounds vulnerabilities were found in D-Link AC2600 (DIR-2640) firmware version 1.01B04. They allow privilege escalation from ordinary to administrator permissions, leading to local arbitrary code execution.
Risk Assessment
An attacker with local access can gain full control over the device, and by combining this vulnerability with others, can achieve remote code execution, posing a serious threat to network security.
Recommendation
Immediately update the D-Link AC2600 (DIR-2640) firmware to the latest available version if a patch is released, or consider replacing the device with a supported model.

- 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.

Original NVD description (English source)
There are multiple out-of-bounds vulnerabilities in some processes of D-Link AC2600(DIR-2640) 1.01B04. Ordinary permissions can be elevated to administrator permissions, resulting in local arbitrary code execution. An attacker can combine other vulnerabilities to further achieve the purpose of remote code execution.
