First empirical map of the glob ecosystem: 1,966 open-source projects, 1,355 GitHub issues, 444 CVEs and 361 StackOverflow posts across six ecosystems - showing a stark divide between implementation feature sets and what developers actually use.
Security is the dominant concern, not a corner case: vulnerabilities account for almost a quarter of all developer discussions about globs.
Lack of standardization produces inconsistent matching semantics across tools, breaking portability and creating exploitable behavior differences.
The authors propose GlobSpec, a formal specification meant to resolve semantic ambiguities and close the expressiveness gap between implementations and developer needs.

Why it matters
Glob pattern inconsistencies across ecosystems are tied to 444 real CVEs; the paper's GlobSpec proposal offers a path to safer, more portable file-matching behavior in build tools, agents, and MCPThe Model Context Protocol — an open standard that lets any AI assistant plug into any tool or data source without custom integration code.Full definition → servers that rely on globs.
Key quotes
“Our analysis reveals that security vulnerabilities are not corner cases, but a dominant concern, comprising almost a quarter of all developer discussions.”
“We propose a path forward through standardization and introduce a formal specification for globs, GlobSpec, designed to resolve semantic ambiguities and bridge the expressiveness gap between current implementations and developer requirements.”
