How do I mitigate GHSA-r82c-j4mq-5xfw 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-r82c-j4mq-5xfw?

O3 pinpoints whether GHSA-r82c-j4mq-5xfw is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-r82c-j4mq-5xfw actively exploited in the wild?

No public exploit code has been indexed for GHSA-r82c-j4mq-5xfw 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.
