Adobe Acrobat Chrome Extension Flaw Exposed WhatsApp Web Data
- Engineer — Plan: The patched Adobe Acrobat Chrome extension (CVE-2026-48294) could allow malicious sites to silently read WhatsApp Web session data; public PoC exists but EPSS is 0.01 and KEV-unlisted. Audit enterprise browser policies and confirm the extension has been updated to the patched version across managed endpoints.
- SOC/IR — Learn: No active exploitation campaign or IOCs published; the HermeticReader attack chain demonstrates how a privileged browser extension can be abused to silently cross-read web app data — useful context for evaluating browser extension detection coverage but no immediate hunt or rule-write warranted.
- Leader — Skip
- Signals: CVE-2026-48294 — CISA KEV: not listed, EPSS 0.01, public PoC on GitHub
