COSMIC Bans AI-Generated Contributions as a GNOME Developer Urges Projects to Accept AI-Found Vulnerability Reports

System76's COSMIC desktop now requires contributors to declare no AI-generated content in pull requests, while GNOME's Michael Catanzaro argues projects should still accept AI-generated vulnerability reports.

Overview

Two Linux desktop projects are taking opposite positions on AI in their contribution workflows. System76’s COSMIC desktop now asks contributors to declare that a pull request contains no AI-generated content, according to The Register. In GNOME, developer Michael Catanzaro is urging projects that ban AI-generated content to carve out an exception for vulnerability reports, as he argues in a blog post dated October 2.

What COSMIC Requires

COSMIC’s pull request template asks contributors to acknowledge a checklist, and the first item reads: “I have not included any LLM (also known as AI) generated content in this PR, including code, comments, and descriptions.” The template also states that pull requests without a completed checkbox will be closed.

The Register describes the rule as covering the code, its documentation or notes, and the submission request itself, while noting that contributors may still use AI to teach themselves or to find bugs. It adds that some GNOME sub-projects also restrict AI-generated contributions: the GNOME Calendar contributing guide bars contributions generated by large language models and chatbots, and the GNOME Extensions review guidelines say “Extensions must not be AI-generated,” although The Register reports that Extensions permits AI learning aids and code completion.

Catanzaro’s Argument for Vulnerability Reports

In a June post, Catanzaro wrote that many GNOME projects use a policy banning all LLM-generated contributions, and that this policy extends to issue reports. He said he would not object to a ban on AI-written code but objected to applying it to bug reports. His October post goes further. He writes that “Projects that choose to ban AI-generated content in issue reports might as well ban all vulnerability reports; the effect will be approximately the same.” He proposes that GNOME maintainers rewrite their AI contribution policies to permit AI-generated vulnerability reports, and that projects continuing to prohibit them “are no longer suitable dependencies for GNOME, and should be developed someplace other than GNOME GitLab.”

Catanzaro supports the position with GNOME’s own data. His post reports 141 GNOME CVEs for 2026 through September 30, and he writes that AI is the primary cause of an increase to roughly an order of magnitude more CVEs than three years ago. He also reports that GNOME’s bug bounty program for GLib, glib-networking and libsoup, sponsored by the Sovereign Tech Resilience program of Germany’s Sovereign Tech Agency, received 298 reports in total, of which 71 were accepted. The program paid “€183,900” for those 71 vulnerabilities, according to the post. He attributes the closure of the program, whose last report was submitted on February 23, 2026, to his being overwhelmed by AI-generated reports, and writes that bounty-driven submissions were of worse quality than those sent through regular issue trackers.

The Burden on Maintainers

Catanzaro does not describe AI-generated reports as costless. He writes that they are often verbose, can exaggerate severity, are occasionally incorrect, and sometimes include fabricated data such as fake stack traces, and that high volumes can overwhelm volunteer maintainers. He also writes that he has ended security tracking for new issue reports and that nobody else has volunteered to take it over.

Readers of his June post raised the maintainer-workload objection directly. One commenter wrote that AI-generated reports are a form of denial-of-service on volunteers and that some repositories choose a middle ground in which reporters use AI to find a bug but must understand and write up the report themselves. Catanzaro replied in the comments that GIMP was then the only GNOME project receiving a high volume of AI-generated reports and that GIMP developers were not complaining.

Wider Context

The Register’s reporter, Liam Proven, writes that accepting AI-generated bug reports could prove “the thin edge of a wedge” toward AI-assisted triage, fixes and eventually core components, and notes that Debian and the Linux kernel already allow AI-assisted contributions. That is the publication’s own assessment rather than a stated GNOME plan.

The split echoes other recent project-level decisions. The Machine Herald has previously reported on Oracle barring AI-generated code from OpenJDK, Node.js codifying an AI use policy, and Google pausing product vulnerability rewards in its open-source bug bounty.

What We Don’t Know

  • None of the sources reviewed reports that any GNOME project has changed its AI policy in response to Catanzaro’s proposal; it is a proposal from one developer.
  • The sources do not say whether other COSMIC repositories or System76 products apply the same rule beyond the cosmic-epoch pull request template.
  • Catanzaro’s CVE counts are his own tallies of issues reported to GNOME Security, and he notes that part of the increase reflects maintainers flagging issues more often.
