Details

The Content No Cache: prevent specific content from being cached plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 0.1.2 via the eos_dyn_get_content action due to insufficient restrictions on which posts can be included. This makes it possible for unauthenticated attackers to extract data from password protected, private, or draft posts that they should not have access to.

Vulnerability from github – Published: 2026-01-10 06:30 – Updated: 2026-01-10 06:30

Details

The WooCommerce Square plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.1 via the get_token_by_id function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to expose arbitrary Square "ccof" (credit card on file) values and leverage this value to potentially make fraudulent charges on the target site.

Summary
Duplicate Advisory: Tool group policy callers could accept unvalidated group IDs
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-985f-72mj-8gf7. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.4.25 contains an input validation vulnerability in tool group policy callers that accept unvalidated group IDs. Attackers who can supply a group ID to the policy resolver could trigger incorrect group-policy decisions for tool invocations, potentially bypassing intended access controls.

Vulnerability from github – Published: 2025-10-21 18:30 – Updated: 2025-10-21 21:33
VLAI
Details

Moodle OpenAI Chat Block plugin 3.0.1 (2025021700) suffers from an Insecure Direct Object Reference (IDOR) vulnerability due to insufficient validation of the blockId parameter in /blocks/openai_chat/api/completion.php. An authenticated student can impersonate another user's block (e.g., administrator) and send queries that are executed with that block's configuration. This can expose administrator-only Source of Truth entries, alter model behavior, and potentially misuse API resources.

An authenticated student can impersonate another user\u0027s block (e.g., administrator) and send queries that are executed with that block\u0027s configuration. This can expose administrator-only Source of Truth entries, alter model behavior, and potentially misuse API resources.",

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
