Title
OneSignal – Web Push Notifications <= 3.8.0 - Missing Authorization to Authenticated (Subscriber+) Post Meta Deletion via 'post_id'
Summary
The OneSignal – Web Push Notifications plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 3.8.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete OneSignal metadata for arbitrary posts.

Title
OneSignal – Web Push Notifications <= 3.6.1 - Missing Authorization to Unauthenticated Plugin Settings Update
Summary
The OneSignal – Web Push Notifications plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the settings handling functionality in all versions up to, and including, 3.6.1. This is due to the plugin processing POST requests without verifying user capabilities or nonces. This makes it possible for unauthenticated attackers to overwrite the OneSignal App ID, REST API key, and notification behavior via direct POST requests.

Title
OneSignal repository github action command injection
Summary
OneSignal is an email, sms, push notification, and in-app message service for mobile apps.The Zapier.yml workflow is triggered on issues (types: [closed]) (i.e., when an Issue is closed). The workflow starts with full write-permissions GitHub repository token since the default workflow permissions on Organization/Repository level are set to read-write. This workflow runs the following step with data controlled by the comment `(${{ github.event.issue.title }} – the full title of the Issue)`, allowing an attacker to take over the GitHub Runner and run custom commands, potentially stealing any secret (if used), or altering the repository. This issue was found with CodeQL using javascript’s Expression injection in Actions query. This issue has been addressed in the repositories github action. No actions are required by users. This issue is also tracked as `GHSL-2023-051`.

Title
OneSignal – Web Push Notifications <= 3.8.0 - Missing Authorization to Authenticated (Subscriber+) Post Meta Deletion via 'post_id'
Summary
The OneSignal – Web Push Notifications plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 3.8.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete OneSignal metadata for arbitrary posts.

Title
OneSignal – Web Push Notifications <= 3.6.1 - Missing Authorization to Unauthenticated Plugin Settings Update
Summary
The OneSignal – Web Push Notifications plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the settings handling functionality in all versions up to, and including, 3.6.1. This is due to the plugin processing POST requests without verifying user capabilities or nonces. This makes it possible for unauthenticated attackers to overwrite the OneSignal App ID, REST API key, and notification behavior via direct POST requests.

Title
OneSignal repository github action command injection
Summary
OneSignal is an email, sms, push notification, and in-app message service for mobile apps.The Zapier.yml workflow is triggered on issues (types: [closed]) (i.e., when an Issue is closed). The workflow starts with full write-permissions GitHub repository token since the default workflow permissions on Organization/Repository level are set to read-write. This workflow runs the following step with data controlled by the comment `(${{ github.event.issue.title }} – the full title of the Issue)`, allowing an attacker to take over the GitHub Runner and run custom commands, potentially stealing any secret (if used), or altering the repository. This issue was found with CodeQL using javascript’s Expression injection in Actions query. This issue has been addressed in the repositories github action. No actions are required by users. This issue is also tracked as `GHSL-2023-051`.
