Misskey is an open source, federated social media platform. IVersions 8.63.0 and later, but prior to 2026.5.4, contain a vulnerability that can cause the Misskey web client to slow down or crash when it applies a malformed theme. This issue has been fixed in version 2026.5.4.
CVE-2026-46714
This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 82% 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).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
