CVE-2026-104079

Status: Awaiting AnalysisMedium (5.3)—

Envira Gallery Lite before 1.16.2 contains a missing authorization vulnerability in its gallery conversion REST endpoint that allows lower-privileged authenticated users to create and publish Envira galleries without the required capabilities, because the endpoint only checks edit permissions on the source post and uses a hard-coded publish status. Attackers can also supply arbitrary caller-controlled image IDs without ownership verification to publish unauthorized content using attachments they are not authorized to use.

CVSS

Exploitation probability (EPSS)

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
