A proof-of-concept (PoC) exploit has been publicly released for CVE-2026-2005, a critical remote code execution (RCE) vulnerability affecting PostgreSQL’s pgcrypto extension. Zero-dayexploit monitoring

The flaw, rooted in legacy code dating back nearly two decades, highlights the long-standing risks associated with memory handling issues in widely deployed database systems.

The vulnerability exists in the PGP session key parsing logic within the pgcrypto module, where a heap-based buffer overflow can be triggered using a specially crafted PGP message.
