How do I fix GHSA-26gg-9gv2-v27j?

Update org.springframework.ai:spring-ai-pdf-document-reader to 1.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-26gg-9gv2-v27j is resolved across your whole dependency graph.

How do I detect GHSA-26gg-9gv2-v27j in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.ai:spring-ai-pdf-document-reader. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-26gg-9gv2-v27j if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-26gg-9gv2-v27j?

O3 pinpoints whether GHSA-26gg-9gv2-v27j is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
