Microsoft is telling companies to treat their own AI agents like a new employee — one with a login nobody has reviewed.
The problem: an agent usually inherits its sponsor's access, so an expense bot can reach everything its boss can. Microsoft's new Dynamic Permissions inverts that. An agent starts with no authority at all and gets only what one approved task needs, for only as long as it runs. Access is time-bound and shrinks back as the work changes or ends, and an agent can never get rights its human user lacks.
Dynamic Agent Risk scores each agent continuously from identity, data, endpoint, cloud and runtime signals. When risk climbs, the response is graduated, not a kill switch: keep reads but block writes, narrow reachable data, demand human approval, or isolate the runtime. Reporting says it is in private preview.

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.
