A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: < 4.1.5
Patched in 4.1.5
Vulnerable: <= 3.0.5
Details
Parsing deeply nested JSON structures can hit Go's stack limit, causing the application to crash.
Note: this advisory is the same as https://github.com/go-jose/go-jose/security/advisories/GHSA-6mp9-8xrw-74r4.
Denial of service vulnerability. Any application that parses untrusted JSON via go-jose is exposed.
Reject large inputs before parsing them.
Thanks to Dohyun Kim (@azza999), Joshua Rogers of AISLE Research, and Sueun Cho for alerting us to the need to patch this.
EPSS, exploit probability
Low0.29%
estimated chance of real-world exploitation in the next 30 days, higher than 21.7% of every CVE FIRST.org scores
Refreshed 10/28/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
