CVE-2026-105849

Status: Awaiting AnalysisHigh (7.7)—

Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, users with ordinary read access to other authentication documents in a collection with useAPIKey enabled can obtain active API keys and exercise the target accounts' permissions until those keys are rotated or disabled. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

CVSS

Exploitation probability (EPSS)

FIRST hasn't scored this CVE yet (usual for very recent or rejected CVEs).

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.
