mxml: Mini-XML 4.0.5 contains a memory leak vulnerability in mxml_load_data() during malformed XML parsing
CVE-2026-88385 is fixed in mxml on 1 platform by DEBIAN-CVE-2026-88385 (version 4.0.6-2), released October 1, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
