…ent (#264077) ## Summary Fixes CVE-2026-35213 — a Regular Expression Denial of Service (ReDoS) vulnerability in `@hapi/content@6.0.0` which is a transitive dependency of `@hapi/hapi` (Kibana's HTTP server framework). Upgrades `@hapi/hapi` from `21.4.4` to `21.4.8`, which cascades into patching the full vulnerable dependency chain: | Package | Before | After | Role | |---|---|---|---| | `@hapi/hapi` | `21.4.4` | `21.4.8` | Direct dependency (HTTP server) | | `@hapi/subtext` | `8.1.1` | `8.1.2` | Request body parsing (requires `@hapi/content ^6.0.1`) | | `@hapi/pez` | `6.1.0` | `6.1.1` | Multipart form parsing (requires `@hapi/content ^6.0.1`) | | `@hapi/content` | `6.0.0` | `6.0.1` | **Vulnerable package — contains the fix** | ### Vulnerability Details `@hapi/content@6.0.0` has a ReDoS vulnerability in its `Content-Type` header parsing regex. A maliciously crafted `Content-Type` header sent to any Kibana HTTP endpoint could cause catastrophic backtracking, exhausting CPU and causing a denial of service. No authentication is required to exploit this. - **CVE:** CVE-2026-35213 - **Severity:** High - **Fix:** Upgrade `@hapi/content` to `6.0.1` ([upstream commit](hapijs/content@ac9a2de), [upstream PR](hapijs/content#38)) - **Tracking issue:** elastic/security#9673 ### Impact Assessment All network-accessible Kibana deployments running `@hapi/content@6.0.0` are potentially affected. The exploit requires no privileges and targets the HTTP layer. ## Test plan - [ ] CI passes — confirms the hapi version bump has no regressions in Kibana's HTTP layer, routing, and request handling - [ ] Confirm `yarn.lock` no longer contains `@hapi/content@6.0.0` after bootstrap Made with [Cursor](https://cursor.com)
