Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from the original implementation of the filter method in filter.php, which directly applied a complex regex to the entire input via preg_replace_callback. The regex's structure (with nested quantifiers and ambiguous anchors) made it susceptible to ReDoS when processing maliciously crafted <a> tags. The commit explicitly addresses this by introducing input splitting and size checks, confirming the function's role in the vulnerability.
