CVE-2026-88385 (GCVE-0-2026-88385)

Vulnerability from cvelistv5 – Published: 2026-09-24 00:00 – Updated: 2026-09-24 16:21

Summary

Mini-XML 4.0.5 contains a memory leak vulnerability in mxml_load_data() during malformed XML parsing. Specially crafted XML input can cause text nodes allocated by mxmlNewText() to become unlinked before a parse error transfers control to the cleanup path. These orphaned nodes are not released, resulting in a persistent memory leak on each parsing attempt. Repeated attacker-controlled requests can cause cumulative memory exhaustion and denial of service.

Severity

No CVSS data available.
