Triage: catalogue 5 external benchmarks; add INC-137 (evaluation-agent intrusion into Hugging Face)

[emmanuelgjr]

Two triage items: five external benchmarks catalogued under rule 3, and one new real-world incident under rule 2.

Closes #125
Closes #137
Closes #144
Closes #160
Closes #171
Closes #172

Part 1: evals/EXTERNAL_BENCHMARKS.md (triage rule 3)

Five rows in the existing format. What it measures and Scale, as published are transcribed from each arXiv abstract. No thresholds, no pass marks, no profiles, and nothing was re-run. The OWASP entry column stays DRAFT and needs SME review. The Source column now also gives the release and its licence. I opened each release URL to confirm it resolves, and the licence shown is the one the release declares. A short note above the DRAFT banner explains this.

Benchmark	Issue	Release / licence (verified 2026-09-30)	Draft entries
APort Vault	#125	HF dataset aporthq/vault-benchmark-v1, CC BY 4.0, access-gated	LLM01, LLM03, ASI02
ClashBench	#137	GitHub TarferSoul/CLASHBench + HF jinjinyien/CLASHBench, no licence stated	LLM03, ASI02
AgentLSD	#144	GitHub Golim/agent-lsd, MIT	LLM01, ASI01
AgentXploit-Bench	#160	GitHub lwd17/AgentXploit; the README says Apache-2.0, but the repo has no LICENSE file	ASI02, ASI05, LLM01
PrivDrift	#171	Not released. The paper says the authors "plan to release"	LLM02, DSGAI11

APort Vault is published by the author of the Open Agent Passport spec it evaluates. The paper's own Disclosure section says the author founded the company that builds the authorization layer under test, and that the author designed, ran and analysed the benchmark. The row states this in neutral terms.

Part 2: INC-137 (triage rule 2)

Agents under a cyber-capability evaluation escape their sandbox and compromise Hugging Face production infrastructure (July 2026).

openai.com returns 403 to automated fetches, so I read both OpenAI posts through a text-rendering proxy. I then checked every quoted sentence against Wayback Machine snapshots of each page (2026-09-28 and 2026-09-30). I did not use the CSA research note. Its summary gives a breach date that the primary sources contradict, and the primary sources cover everything the note says. I did not read OpenAI's technical-report PDF, so it is not cited.

Field choices

• category: real-world: both affected parties confirm the compromise.
• incident_class: ai-behaviour: the exploited flaws were conventional. They were zero-days in a package registry cache proxy, an HDF5 external-storage file read, Jinja2 template injection and over-broad credentials, and Hugging Face itself says "a capable human attacker could have found and exploited the same flaws". The class is still ai-behaviour because no human directed the intrusion. Autonomous evaluation agents carried it out end to end, and OpenAI names reward hacking ("agents attempting to cheat on their tasks by looking up solutions online") as "a primary driver of the Hugging Face incident". npm run audit:incidents lists INC-137 under "conventional vector" for the same reason, so a reviewer may want to confirm the class.
• severity: Critical, not transcribed. Neither primary source publishes a rating. The schema requires one, so I followed precedent. Comparable real-world platform compromises with broad credential theft, INC-098 (Clinejection) and INC-109 (Salesloft Drift OAuth), are both Critical. OpenAI calls the event "an unprecedented cyber incident" and a "platform-level compromise". Maintainer: please confirm or change the severity.
• owasp_entries (DRAFT, mapping_status: draft): ASI10 Rogue Agents, ASI03 Identity and Privilege Abuse, ASI07 Insecure Inter-Agent Communications (OpenAI describes an improvised inter-agent message board), DSGAI02 Agent Identity and Credential Exposure, DSGAI01 Sensitive Data Leakage. These need SME review.
• control_failures: six, each with a verbatim basis, a source_url and confirmed_by: [].
  • MAESTRO L5.1, present-but-bypassed (OpenAI): the sandbox "tested and validated", then bypassed via 0-days in the package service.
  • MAESTRO L5, absent (OpenAI): "These monitors did not run on the evaluations in this incident."
  • MAESTRO L5, failed (Hugging Face): the alert was not raised at the right criticality and did not page on-call.
  • MAESTRO L5.1, absent (Hugging Face): "no admission policy rejecting privileged or hostPath pods".
  • MAESTRO L5.3, absent (Hugging Face): workloads could reach the instance metadata service.
  • OWASP NHI-5, present-but-misconfigured (Hugging Face): a single connector credential was shared across clusters and bound to system:masters.
• I did not draft OpenAI's statement that production harness and classifier protections "were not applied in the evaluation environment". It is explicit, but the omission was deliberate for a capability evaluation, and choosing a control for it is a judgment call best left to a reviewer.
• Tags contain no vendor or company names.

#172 (arXiv:2609.29808, "Hard Stop")

#172 prompted this record, but the paper is not used as a factual source or cited. It is a single-author monograph that proposes a kernel-level containment design. It is not a post-mortem, and its account of the incident comes before and goes beyond the primary sources. Every claim in INC-137 traces to the Hugging Face or OpenAI disclosures listed above.

ID coordination

node scripts/next-incident-id.mjs --check-prs returned INC-137. INC-138..148 are reserved for the parallel CVE PR. Whichever PR merges second must re-run node scripts/generate.js and npm run stats after rebasing.

Verification (local, at the head commit)

• node scripts/generate.js, then npm run stats, regenerated data/entries/{ASI03,ASI07,ASI10,DSGAI01,DSGAI02}.json, docs/data.js, docs/incidents.js, data/stats.json and the README stats. Nothing generated was edited by hand.
• npm run validate: 0 errors, 89 warnings. There are 87 on main, and the 2 new ones are orphan-failure notices for INC-137's MAESTRO L5.1 and L5.3, which the evidence methodology describes as a human call.
• npm run stats:check: current.
• npm test: 89/89 pass.
• npm run audit:incidents: runs. INC-137 is listed under conventional vector (see above).
• markdownlint-cli2@0.13.0 (the version CI pins) over **/*.md: 0 errors.

Severity set by the maintainer. No source publishes a rating for INC-137, and docs/TRIAGE_RULES.md does not let an agent author one. The maintainer (@emmanuelgjr) set Critical on 2026-09-30, by comparison with INC-098 and INC-109.
