Firebirdsql

Firebirdsql is an open-source relational database engine that, despite a narrow product footprint centered on Firebird itself, occupies a position among more prominent database platforms in the vulnerability landscape. Its vulnerability profile is anchored in memory-safety and input-handling weakness classes—including buffer-boundary violations, NULL-pointer dereferences, improper input validation, and information-exposure flaws—that are characteristic of native database implementations managing untrusted query and network input. Notably, vulnerabilities affecting this vendor frequently acquire public exploit code, reflecting the accessibility of the open codebase and the appeal of database engines as targets for proof-of-concept research and operational testing. Defenders deploying Firebird should monitor upstream releases for memory-safety and parsing fixes, particularly where instances are network-exposed or process untrusted client queries; current severity, exploitation activity, and exposure counts are shown alongside this summary.
