ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. The BluFi example bundled in ESP-IDF was vulnerable to memory overflows in two areas: Wi-Fi credential handling and Diffie–Hellman key exchange. This vulnerability is fixed in 5.4.1, 5.3.3, 5.1.6, and 5.0.9.
CVE-2025-55297
This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 81% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
