Django: Closing the Gaps on Input Validation and Edge Cases
Today's merges tighten up validation and correctness at the edges — rejecting malformed input in URLs, fixing a long-standing SQLite decimal conversion bug, and allowing GEOS geometry collections to nest as the spec always intended. A pending migration ordering fix and an admin widget patch round out the queue.

Good day, and welcome to Django, your developer briefing for August 17, 2026.
The clearest thread running through today's merges is edge-case correctness: several fixes close gaps where Django accepted or produced data it shouldn't have.
Start with input validation. PR #21787, from maycuatroi1, adds null characters to URL Validator's list of unsafe characters. Tabs and newlines were already rejected after a past fix, but null bytes slipped through — meaning a URL containing a null character could pass validation when it shouldn't. This brings the…
Similarly, sarahboyce's PR #21779 fixes a SQLite-specific bug where decimal field values without an explicit precision weren't converting correctly. This one's been open in various forms since ticket 24920, and the fix, also captured in commit a3e6e7d, credits both the original reporter and reviewer — a reminder…
On the geospatial side, jacobtylerwalls' PR #21785 fixes a real limitation, not just a format quirk: GEOS geometry collections couldn't be constructed from other geometry collections, even though nothing in the underlying data format prevented it. That restriction is now gone, letting code compose collections more…
