Grafana -- OpenFeature evaluation API reads input data with no bounds

2026-05-26 · CVE-2026-27880 · VuXML entry

https://grafana.com/security/security-advisories/cve-2026-27880 reports: The OpenFeature feature toggle evaluation endpoint reads unbounded values into memory, which can cause out-of-memory crashes.

Affected versions

• grafana >= 12.1.0 < 12.1.10; >= 12.2.0 < 12.2.8; >= 12.3.0 < 12.3.6; >= 12.4.0 < 12.4.2

By system

0 still vulnerable, 2 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
