8.2 highCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:HCVE-2026-47710 BACnet Stack: Loop reference to long Structured View description causes stack-buffer-overflow
High (8.2) in bacnet-stack bacnet-stack. EPSS 0.3% estimated probability of exploitation activity in the next 30 days.
BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4, 1.5.1, and 1.6.0, a stack-buffer-overflow can be triggered in the current master branch when a Loop object reads a referenced property through its default timer path and the referenced property is OBJECT_STRUCTURED_VIEW / PROP_DESCRIPTION containing a long attacker-controlled string. This issue has been patched in versions 1.4.4, 1.5.1, and 1.6.0.

Use https://cve.bz/api/public/cves/CVE-2026-47710?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-47710?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-47710 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
