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-5x9h-93gp-chpj?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-5x9h-93gp-chpj can be triaged on real exposure rather than presence alone.

Is GHSA-5x9h-93gp-chpj actively exploited in the wild?

No public exploit code has been indexed for GHSA-5x9h-93gp-chpj yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.
