CVE-2026-102496: Vulnerability in Apache Software Foundation Apache XMLSchema
Apache XmlSchema doesn't limit how deeply schema structures can be nested when it builds its schema model, so a malicious schema can make parsing recurse until the stack overflows. This causes a denial of service. Users are recommended to upgrade to version 2.3.3, which fixes this issue.
AI Analysis
Technical Summary
Apache XMLSchema does not restrict the depth of nested schema structures during schema model building. A maliciously crafted schema can exploit this by causing the parser to recurse deeply until a stack overflow occurs, leading to denial of service. The vulnerability affects versions from the initial release up to but not including 2.3.3. Upgrading to version 2.3.3 resolves the issue.
Potential Impact
Denial of service due to stack overflow caused by unbounded recursion in schema parsing. This can disrupt availability of applications using vulnerable versions of Apache XMLSchema.
Mitigation Recommendations
Upgrade Apache XMLSchema to version 2.3.3 or later, which contains the fix for this vulnerability.
