CVE-2026-116586: Go JOSE: Panics in JSON parsing

MediumCVSS 6.9 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 27/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.29% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: go-jose go-jose 4.1.5; azl3 azcopy 10.25.1-10 on Azure Linux 3.0 Release Notes; azl3 cert-manager 1.12.15-15 on Azure Linux 3.0 Release Notes.

Low priority for now. Upgrade to go-jose go-jose 4.1.5; azl3 azcopy 10.25.1-10 on Azure Linux 3.0 Release Notes; azl3 cert-manager 1.12.15-15 on Azure Linux 3.0 Release Notes or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. Prior to 4.1.5, parsing attacker-controlled JSON through go-jose allows deeply nested arrays or objects to exceed Go's stack limit. The resulting stack overflow crashes the application and permits denial of service in applications that parse untrusted JSON through go-jose. This issue is fixed in version 4.1.5.
