Avoiding Untrusted Input in Dev Tools
There is a significant security risk associated with passing untrusted input to certain functions or glob brace patterns, particularly when upgrades to safer versions are not feasible. Users are advised to implement workarounds, such as limiting input size, to mitigate potential vulnerabilities.
5 different people have complained about this since 20 Sept 2026, most recently on 24 Oct 2026. 2 of them in the last 30 days.

Questions about this idea
- Is Avoiding Untrusted Input in Dev Tools a startup idea?
- Not directly. These are complaints about a product or service people already use, and the fix belongs first to that provider. The page shows what is frustrating users and how badly — not an open market to start a company in.
- How many people have this problem?
- 5 different people described it independently, in 7 mentions, the earliest from 20 Sept 2026 and the most recent from 24 Oct 2026. The quotes, with dates and links to the originals, are in the Evidence section.
- Is this problem getting worse?
- Status: steady — no change the counts can show. 2 people raised it in the last 30 days and 2 in the 30 days before; the status compares its share of everything collected from the same source, so collecting more or less cannot create a trend.
