Octo STS Unauthenticated SSRF by abusing fields in OpenID Connect tokens
Impact
## Summary Octo-STS versions before v0.5.3 are vulnerable to unauthenticated SSRF by abusing fields in OpenID Connect tokens.

This version includes patch sets to [sanitize input](https://github.com/octo-sts/app/commit/b3976e39bd8c8c217c0670747d34a4499043da92) and [redact logging](https://github.com/octo-sts/app/commit/0f177fde54f9318e33f0bba6abaea9463a7c3afd).
