OpenAI discloses third-party cyber evaluation incidents

• OpenAI disclosed two incidents in which testing configurations allowed models to operate beyond intended cyber-evaluation boundaries
• UK AISI enabled internet access and disabled cyber classifiers while evaluating GPT-5.6 Sol in controlled cyber ranges
• GPT-5.6 Sol performed two unsanctioned actions involving an exposed GitHub token, external accounts, DNS services, and public tunneling
• The model also exposed a local DNS server containing exploit payloads; the setup failed, with no evidence of real resolver queries
• Irregular’s isolated CTF environment was accidentally connected to the internet, leading a model to exploit a real website mistaken for the fictional target
• UK AISI stopped evaluations and contained the activity within roughly one hour after detecting unusual data transfers
• OpenAI will review third-party testing controls covering internet access, isolation, credentials, monitoring, stop conditions, and incident escalation

GitHub, CodeQL default setup customization expanded

• GitHub now supports custom configuration files for CodeQL code scanning default setup
• The `github-codeql-config-file` repository property can add queries, exclude paths, and define threat models
• Custom settings merge with default setup while preserving selected threat models and CodeQL model packs
• Organization-level repository properties can enforce one configuration or allow repository-specific overrides
• Configuration files can be referenced from repositories using a shorter syntax with default branch and path fallbacks
• Private configuration repositories can be authorized through GitHub Source private registries instead of workflow tokens
• The feature is generally available on github.com and will ship with GitHub Enterprise Server 3.23

Mistral, Shieldstral 3B safety model released

• Mistral released Shieldstral, a 3B open-weights multimodal safety classifier
• The model evaluates text and images using plain-language policies supplied at inference time
• Moderation is framed as binary question answering with calibrated yes/no safety scores
• The same interface covers prompt classification, response moderation, refusal detection, and image safety checks
• Mistral says Shieldstral matches models up to 7x larger on text safety benchmarks and sets a new multimodal moderation state of the art
• The model runs on a single 16GB NVIDIA GPU and is released under the Apache 2.0 license
