CVE-2026-5205: Critical SSRF in Chatwoot — How a Single Upload Parameter Exposes Cloud Credentials
A deep dive into a critical Server-Side Request Forgery (SSRF) vulnerability in Chatwoot's upload endpoint (≤ v4.12.1). The /api/v1/accounts/:id/upload endpoint accepts an external_url parameter validated only by a scheme check, allowing any authenticated agent to force the server to fetch arbitrary internal URLs. The full response body is returned in-band through ActiveStorage blobs — turning the upload endpoint into a full-read proxy. Live exploitation on a DigitalOcean droplet confirmed in-band exfiltration of cloud metadata including droplet ID, hostname, SSH public keys, and full metadata bundles. Fixed in v4.13.0.

DORA Third‑Party Risk for Mobile AppSec: SDK Governance and Audit‑Ready Evidence Packs
A deep dive into DORA-focused third‑party risk for mobile AppSec, showing why embedded SDKs and runtime providers demand release‑scoped governance because vulnerabilities persist across multiple app versions in the wild and provider outages directly break critical journeys. It outlines an audit‑ready approach built on per‑release SDK inventories and diffs, approval/ban rules, patch SLAs with time‑boxed exceptions, and evidence packs that stay version‑scoped, indexed, and quickly retrievable.
