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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-24 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-88385.json)","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":216685,"id":"CVE-2026-88385","ts":1791314053632,"field":"cvss","old":"7.5","new":"6.5"},{"seq":216684,"id":"CVE-2026-88385","ts":1791314053632,"field":"severity","old":"high","new":"medium"},{"seq":216641,"id":"CVE-2026-88385","ts":1791310381794,"field":"exploit_available","old":"false","new":"true"},{"seq":210677,"id":"CVE-2026-88385","ts":1790322169153,"field":"cvss","old":null,"new":"7.5"},{"seq":210676,"id":"CVE-2026-88385","ts":1790322169153,"field":"severity","old":"none","new":"high"}]}
