Miggo AIRoot Cause Analysis

The vulnerability stems from improper OGNL expression evaluation in URL/A tag parameters. The patch added enableOGNLEvalExpression checks in OgnlUtil.compile() and modified signature to include context. The vulnerable versions' compile() method (without context parameter) lacked eval expression validation, and setValue() propagated this insecure compilation. The GHSA/CVE analysis explicitly links OGNL evaluation to RCE via these code paths.
