CrewAI shipped two releases within about 26 hours of each other this week: **1.15.13** on August 7 at 21:13 UTC, and **1.15.14** on August 8 at 22:57 UTC. The first is a security patch worth acting on quickly if you're running CrewAI in production; the second is a smaller architectural change aimed at teams bridging open-source and enterprise usage. ## 1.15.13: An h2 Request-Smuggling CVE Gets Fixed The headline item in 1.15.13 is a dependency bump: CrewAI updated its `h2` HTTP/2 library to version **4.4.1** to address [GHSA-6hr6-w5qg-qmwg](https://github.com/advisories/GHSA-6hr6-w5qg-qmwg), tracked as **CVE-2026-71554**. This is a request-smuggling vulnerability in the underlying HTTP/2 implementation — the kind of bug that, left unpatched, could let a malicious actor manipulate how HTTP/2 requests are parsed and routed, potentially bypassing security controls that assume a consistent view of request boundaries between proxies and backends. Because `h2` is a transport-layer dependency rather than something most CrewAI users interact with directly, the fix is a straightforward "update your dependency" situation — there's no application-level migration required. If you're running CrewAI in any internet-facing or multi-tenant configuration, this is worth prioritizing over routine maintenance updates. Alongside the security fix, 1.15.13 also includes two smaller bug fixes: - **LiteLLM provider preservation**: a bug where the provider attribute wasn't correctly preserved for models routed through LiteLLM, which could cause misrouting or incorrect provider-specific behavior downstream. - **Anthropic cache-token underreporting**: a fix for CrewAI undercounting Anthropic's cache-token usage, which matters for anyone tracking cost or token budgets closely — underreported cache tokens would have made actual API costs look lower than they really were. There's also a mention of "hardened brittle LLM event-bus mocks" in the changelog, which is an internal test-infrastructure improvement rather than something that affects runtime behavior. ## 1.15.14: Splitting Runtime Context From the Coding Agent The very next day, CrewAI shipped 1.15.14 with a single headline feature: **"Split runtime context from coding agent and add project ID."** This is an internal architecture change rather than a user-facing feature, and CrewAI's release notes don't go into extensive detail on the mechanics. Based on the framing, the change appears to decouple the runtime execution context — the state and environment an agent runs within — from the coding-agent-specific logic that previously carried it, likely making the runtime context reusable across different agent types rather than tied specifically to coding-agent flows. The addition of a **project ID** is the more concretely useful part for teams operating at scale: it's explicitly framed as supporting **OSS-to-enterprise usage linkage**. If you're running CrewAI's open-source framework but also using CrewAI's enterprise tooling (dashboards, observability, or managed services), a project ID gives CrewAI a stable identifier to connect usage across both surfaces — useful for consolidated reporting, billing, or support without requiring you to manually stitch together open-source telemetry and enterprise account data. ## Why This Matters The security fix in 1.15.13 is the one to act on immediately if you haven't already updated — CVE-2026-71554 is a legitimate request-smuggling issue in a widely-used HTTP/2 library, and the fix is a drop-in dependency bump with no breaking changes. The Anthropic cache-token fix is also worth noting if you've been reconciling CrewAI's reported costs against your actual Anthropic billing and seeing a mismatch — this release should tighten that up. 1.15.14's runtime-context split is lower-urgency for most users, but if your organization straddles CrewAI's open-source and enterprise offerings, the new project ID is a small but useful piece of plumbing for unifying visibility across both. ## Sources 1.
