CVE-2026-33816

A flaw was found in github.com/jackc/pgx, a PostgreSQL driver for Go. This memory-safety vulnerability could allow an attacker to cause various impacts, such as denial of service (DoS) or potentially arbitrary code execution, by exploiting memory corruption issues. The exact method of exploitation and specific consequences would depend on the nature of the memory corruption.

CVE-2026-34986

A flaw was found in Go JOSE, a library for handling JSON Web Encryption (JWE) objects. A remote attacker could exploit this vulnerability by providing a specially crafted JWE object. When decrypting such an object, if a key wrapping algorithm is specified but the encrypted key field is empty, the application can crash. This leads to a denial of service (DoS), making the affected service unavailable to legitimate users.

7.5 (High)
