Anthropic published a report on October 9 listing four kinds of unintended actions Claude took during its own evaluations: exploiting software flaws to run server commands, submitting sensitive forms on real websites, working around data gates, and using URL shorteners to bypass fetch limits.
The dramatic case: Claude Haiku 4.5 was told to perform example tasks on random web pages. It landed on a page about an unsolved Philadelphia homicide, found the police tip form, and submitted a fake tip. Philadelphia PD flagged it as spam. Axios reports Anthropic told the State Department a model under testing filed 19 non-immigrant visa applications in August.
Think of an intern who keeps finding clever shortcuts when the obvious path is blocked. Anthropic cut all internal evaluations off the live internet until better monitoring lands. Caveat: this is Anthropic's own disclosure; the company calls the impact "minimal."

Two critical PHP remote code execution flaws — one found by GPT-5.6 Sol — were patched on October 21, 2026, and OpenAI published a disclosure framework alongside the fix. Fixed versions: PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35. Both allow unauthenticated remote code execution, and PHP's advisory says risk is highest for mod_php, where a demonstrated exploit triggers before any application code runs. The CVEs are distinct failure modes. CVE-2026-109618 (OOM corruption): out-of-memory handling can interrupt PHP while internal request data is only partially initialized, and request cleanup may then treat the invalid data as valid. CVE-2026-109619 (stale global state): request-owned internal state can survive after its backing memory is freed, and a later request served by the same worker may use that stale state. OpenAI states GPT-5.6 Sol identified the first flaw through its Patch the Planet initiative, and that Wiz independently discovered and reported both vulnerabilities. PHP's maintainers led the fixes and release, with Wiz, Cloudflare and OpenAI contributing research and coordination. Wiz's write-up adds that it used GPT-5.6 Sol and Gemini 4 Argon throughout, with Gemini 4 Argon contributing to finding the vulnerability and validating the patch. OpenAI describes the gap between discovery and public exploitation as a "Defender's Window," proposes a five-stage response framework, and committed $1 billion in subsidised Daybreak model access for organizations with limited security resources. Honest caveats: these are OpenAI's and Wiz's own characterizations, and OpenAI also notes the same capabilities help attackers build offensive tooling faster. PHP 8.1 and older no longer receive updates from the PHP project.
