Bumps the python-security group with 1 update in the / directory: httpx2.

Updates httpx2 from 2.7.0 to 2.12.0

Release notes

Sourced from httpx2's releases.

v2.12.0

Highlights

🛡️ Bounded response decompression

httpx2 now decodes gzip, deflate, Brotli, and Zstandard responses incrementally. Each decode step emits at most 1 MiB, so streaming a highly compressed response no longer requires materializing an entire inflated network chunk in memory (pydantic/httpx2#1126).

📦 Shared Zstandard API

Python 3.13 and earlier now use backports.zstd, which provides the same bounded incremental decompression API as compression.zstd on Python 3.14 and later (pydantic/httpx2#1146).

httpx2

Changed

Fixed

httpcore2

No changes since 2.11.0. Version bumped to stay in lockstep with httpx2.

Full Changelog: pydantic/httpx2@v2.11.0...v2.12.0

v2.11.0

Highlights

🌐 Public origin API

httpx2 now includes an immutable and hashable Origin value object, available through URL.origin. It provides normalized scheme, host, and effective port comparisons without including URL paths, queries, fragments, or credentials (pydantic/httpx2#1134).

🛠️ Request compatibility and validation

P1 Badge Restore the release-please version marker

This rewrite drops the # x-release-please-version suffix from the editable package version. The dependency-review job in .github/workflows/ci.yml:66 explicitly requires the exact marked string in uv.lock, so every CI run for this commit fails before uv lock --check; restore the marker after regenerating the lockfile.

P1 Badge Publish the security-fixed dependency floors

Because this is a python-security update, changing only the lockfile leaves the published requirement at httpx2>=2.7.0, so downstream SDK installations may still select the vulnerable release. The parent security checker invoked by .github/workflows/ci.yml:55 rejects this commit first with Add a reviewed contextual transitive security dependency boundary for httpcore2 and, after supplying that boundary, with Raise the published security-fixed minimum for httpx2; raise the runtime httpx2 floor and add the corresponding reviewed httpcore2 constraint.

P1 Badge Add sync and async decompression security tests

Because 2.12.0 is being adopted specifically for bounded incremental decompression and stream cleanup on decoding failures, add focused public-entrypoint tests for both synchronous and asynchronous clients using large compressed responses and malformed compressed streams. The existing large-payload coverage supplies only uncompressed httpx2.Response bodies, so it cannot detect a regression in the security behavior this update is intended to provide.

P2 Badge Update the runnable example lock as part of the fix

When a user launches the documented ./examples/realtime/push_to_talk_app.py, its #!/usr/bin/env uv run entry point uses the adjacent script lock—the local uv lock --help says script locks are written “to a .lock file adjacent to the script itself.” That lock still pins httpx2 2.10.0 at examples/realtime/push_to_talk_app.py.lock:193, so this example environment remains on the pre-fix decompression and stream-cleanup path despite the root upgrade; regenerate the script lock with httpx2/httpcore2 2.12.0 as well.
