CVE-2026-34746: Payload has Authenticated SSRF via Upload Functionality

HighCVSS 7.7 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.30% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: payloadcms payload 3.79.1.

Low priority for now. Upgrade to payloadcms payload 3.79.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Payload is a free and open source headless content management system. Prior to version 3.79.1, an authenticated Server-Side Request Forgery (SSRF) vulnerability exists in the upload functionality. Authenticated users with create or update access to an upload-enabled collection could cause the server to make outbound HTTP requests to arbitrary URLs. This issue has been patched in version 3.79.1.
