Changes

  • Updated uv.lock to reference Starlette 0.50.0

Updates Starlette from 0.48.0 to 0.50.0 to address a critical security
vulnerability where an unauthenticated attacker can send a crafted HTTP
Range header that triggers quadratic-time processing in Starlette's
FileResponse Range parsing/merging logic, enabling CPU exhaustion and
denial-of-service attacks on file-serving endpoints.

Fixed in Starlette 0.50.0.

@ColeMurray this is a uv.lock file. Could you retitle the PR or description appropriately? since this change actually doesn't affect anything that's end user facing (i.e., the lock file is only used when running unit tests on CI for this library -- it's not something that affects any users of the library)
