CVE-2026-60082: CWE-125 Out-of-bounds Read in HMBRAND DBI
DBI versions before 1.651 for Perl do not enforce statement handle consistency with the row. When the statement handle had no fields but the source row was non-empty, the internal row-buffer helper would read from a negative array index. This could be triggered by a caller supplying inconsistent metadata and rows to the prepare method.
AI Analysis
Technical Summary
The vulnerability in HMBRAND DBI (before version 1.651) involves improper enforcement of statement handle consistency with the row data. Specifically, when a statement handle has no fields but the source row is non-empty, the internal row-buffer helper reads from a negative array index, leading to an out-of-bounds read (CWE-125). This can be triggered by supplying inconsistent metadata and rows to the prepare method. The CVSS v3.1 score is 9.1 (critical), indicating network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, high confidentiality impact, no integrity impact, and high availability impact.
Potential Impact
An attacker can cause an out-of-bounds read in the DBI Perl module, potentially leading to a crash or denial of service due to reading invalid memory. The vulnerability does not impact integrity but has high confidentiality and availability impacts as per the CVSS vector. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid supplying inconsistent metadata and rows to the prepare method in DBI. Monitor vendor channels for updates regarding an official fix or mitigation.
