CVE-2026-59341

Sealed Secrets controller (Bitnami) is vulnerable to a decryption oracle via Go template injection in its unauthenticated POST /v1/verify and /v1/rotate endpoints. The root cause is a missing AEAD label binding : the spec.template.data field is excluded from the authenticated-data label, letting ...

CVE-2026-59341 Sealed Secrets: decryption oracle via Go template injection in unauthenticated controller endpoints

A security vulnerability exists in the Sealed Secrets controller's unauthenticated POST endpoints. By submitting a modified payload containing custom Go template logic in spec.template.data, an attacker with internal network access can abuse the handler as a decryption oracle to recover the full...

CVE-2026-54155

node-opcua is an OPC UA implementation for TypeScript and Node.js. Prior to 2.166.0, the UserNameIdentityToken authentication handler in packages/node-opcua-server/source/opcuaserver.ts decrypts an RSA-OAEP password blob but does not verify that the trailing bytes match the current session...

Astra Linux – Vulnerability in python-rsa

In Python-RSA before version 4.1, leading '\0' bytes are ignored during the decryption of ciphertext. This could potentially have security-related implications, such as allowing an attacker to infer that an application uses Python-RSA. Alternatively, the length of the accepted ciphertext may affe...

Astra Linux – Vulnerability in python-cryptography

A flaw was discovered in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which could result in the exposure of confidential or sensitive data...

Astra Linux – Vulnerability in Node.js

Node.js versions that bundle a unpatched version of OpenSSL or run against a dynamically linked version of OpenSSL that is also unpatched are vulnerable to the Marvin attack – https://people.redhat.com/hkario/marvin/. This vulnerability occurs when performing RSA decryption using a private key,...
