Q: Is CVE-2026-8384 being actively exploited?

Not that we know of. CVE-2026-8384 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.23% is the estimated probability that it will be exploited in the next 30 days. That is higher than 14% of all scored CVEs.

Q: How severe is CVE-2026-8384?

CVE-2026-8384 has a CVSS v3 base score of 5.3, rated medium. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

Q: What does CVE-2026-8384 affect?

Published advisories record a fix for jetty (NVD). Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.

CVSS v3

NVD

Description

In Eclipse Jetty, an HTTP URI of this form: /public;/../admin/secret.txt results in an unresolved path of: /public/../admin/secret.txt instead of the expected: /admin/secret.txt Jetty itself is not affected, as it will not serve the secret.txt file because it will not pass the alias checker (only resolved resources are served). However, web applications that rely on resolved paths being provided by Jetty may be confused when receiving an unresolved path.
