将算法从 RS256（非对称）改为 HS256（对称）- POC（CVE-2016-10555） HS256 算法使用密钥来签名和验证每条消息。 RS256 算法使用私钥签名消息，并使用公钥进行身份验证。 如果将从 RS256 改为 HS256，后端代码将把公钥作为密钥，然后使用 HS256 算法验证签名。 致谢： https://www.youtube.com/c/FarahHawa...

signy

signy 面向小型设备的签名URL。 背景 signy 是一个用于在嵌入设备上使用非对称加密生成签名URL的库。签名URL通常用于授予对私有资源（例如由内容分发网络（CDN）提供的资源）的限时访问权限。在嵌入设备的场景中，签名URL可用于使外部系统或同一系统中的另一个组件能够访问特定资源。例如，设备可以生成签名URL并将其传递给性能更强的系统，以便让其代表设备下载资源。 使用 signy 需要一个能够验证其生成的签名URL的服务器。如果与 Golioth 配合使用 signy，则必须将颁发设备证书的证书颁发机构（CA）关联的证书上传到您的项目。 用法 signy...

CVE-2026-85394

python-jose through 3.5.0 fails to properly validate asymmetric keys in HMAC initialization, accepting DER-encoded public keys that lack PEM armor or SSH prefixes. Attackers holding the service's public key can forge HS256 tokens that pass verification when algorithms are not explicitly restricte...

CVE-2026-54874

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: asymmetrickeys – prevented overflow in asymmetrickeygenerateid. Use checkaddoverflow to prevent potential integer overflows when adding the lengths of binary blobs and the size of an asymmetrickeyid structure. Return...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KEYS: prevented NULL pointer dereference in findasymmetrickey. In findasymmetrickey, if all NULL values are passed as arguments to id0,1,2, the kernel will first emit a WARN message, but then there will be an oops because id2 wil...

PT-2026-72474

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Do not allow intra-host migration/mirroring of SNP VMs The intra-host migration/mirroring feature is not fully implemented for SEV-SNP VMs. The proper migration requires additional SNP-specific state such as guest req...

python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...
