CVE-2026-82722
ash_admin LiveView lets clients exhaust BEAM atom table and crash the node.
Is CVE-2026-82722 being exploited?
Not confirmed. CVE-2026-82722 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-82722?
CVE-2026-82722 is rated High with a CVSS score of 8.3. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Yes. A fix has been recorded for CVE-2026-82722. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-82722 affect?
CVE-2026-82722 affects ash_admin versions >=0.1.0 and <1.3.1 (ash-project). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
