Series definition
Measure
One vulnerability record published in curl's public machine-readable vulnerability ledger, counted in the quarter of its public publication date.
Counting
Fetch curl's public JSON record, keep one row per dated vulnerability entry, aggregate by publication quarter, and preserve missing quarters as explicit zero observations.
Date
Use the public `published` date in curl's vulnerability record. The final quarter ends at the latest source date and is marked incomplete rather than extended to the nominal quarter end.
Denominator
All curl vulnerability disclosures in the quarter. No denominator for research effort, submissions, compute, or search time is available.
AI-linked credit
A deterministic finder-credit text classification with separate explicit AI, AI-affiliation-only, fuzzing, and other bands. The central observation numerator combines the first two for backward-compatible sensitivity analysis; it remains noisy attribution evidence, not proof of method use.
Frequency
Quarterly
Data and sources

Fetch curl's public JSON, preserve a canonical raw snapshot, derive a per-record audit table, fill zero quarters, rebuild the compact central observations, and validate severity plus attribution summaries.

Analysis and limits

Analysis

A negative-binomial or Poisson count model with calendar time, a post-2025 level and slope term, quarter effects, and an exposure offset for incomplete periods. Model choice follows dispersion diagnostics.

  • Compare 2025 and partial 2026 with several pre-period windows
  • Exclude the incomplete final quarter
  • Use annual counts to reduce release-batching sensitivity
  • Separate explicit AI markers, AI-affiliation-only credits, and total disclosures
  • Estimate Low and Medium-or-higher disclosure rates separately
  • Estimate curl and OpenSSL jointly with project-specific levels and trends

Limits

  • Disclosure volume depends on search effort, incentives, triage, reporting rules, and release timing.
  • A finder credit can omit AI use or name an AI organization even when a model did not produce the finding.
  • More disclosures, especially low-severity findings, need not imply more important security progress.
  • The latest quarter is incomplete through 2026-09-02.
  • One software project is a pipeline sentinel and reporting control, not a representative measure of science.
