Executive Summary

This vulnerability is in Spring AI PDF Document Reader where analyzing a PDF with a deeply nested or cyclic table of contents causes unbounded recursion, leading to a StackOverflowError in the ingestion thread.

Detection Guidance

Detecting this vulnerability requires checking the version of Spring AI in use. Commands like 'find . -name "spring-ai*.jar" | xargs ls -l' or checking dependency files (e.g., pom.xml, build.gradle) for Spring AI versions 1.0.0-1.0.9, 1.1.0-1.1.8, or 2.0.0 can help identify affected installations.

Impact Analysis

The vulnerability can cause a denial of service by crashing the application due to a StackOverflowError when processing maliciously crafted PDFs. This impacts availability of the system.

Compliance Impact

This vulnerability primarily causes a StackOverflowError in the ingestion thread when processing maliciously crafted PDFs with deeply nested or cyclic table of contents. It does not directly impact data confidentiality or integrity but may lead to service unavailability due to crashes. Compliance impact would be indirect, as prolonged downtime could affect data processing timelines required by GDPR or HIPAA.

Mitigation Strategies

Upgrade to fixed versions: 2.0.1 (OSS), 2.0.0.1 (Enterprise), 1.1.9 (Enterprise), or 1.0.10 (Enterprise). No additional mitigation steps are required beyond updating.
