UnQLite

UnQLite versions through 0.06 for Perl uses a potentially insecure version of the UnQLite library.

UnQLite for Perl embeds the UnQLite library.  Version 0.06 and earlier of the Perl module uses a version of the library from 2014 that may be vulnerable to a heap-based overflow.

CVE-2026-3257 identifies a security vulnerability in the TOKUHIROM UnQLite Perl module, specifically versions 0.06 and earlier. This module embeds an older version of the UnQLite database library dating back to 2014, which contains a heap-based overflow vulnerability. The weakness is categorized under CWE-1395, indicating a dependency on a vulnerable third-party component. Heap-based overflows occur when a program writes more data to a heap buffer than it can hold, potentially corrupting adjacent memory. This can lead to unpredictable behavior including crashes, data corruption, or arbitrary code execution if exploited by an attacker. Since the Perl module uses an outdated embedded library, any application relying on this module inherits the vulnerability. The vulnerability does not require user interaction or authentication, increasing its risk profile. Although no exploits are currently known in the wild and no patches have been published, the presence of this flaw in a widely used embedded database library poses a significant threat to affected systems. The vulnerability affects the confidentiality, integrity, and availability of applications using the vulnerable UnQLite Perl module, especially those handling untrusted input or operating in exposed environments.
